String Language Checking

Hi,
what is the best way to check that a certain string matchs a certain language, for example i have user input name (String) where i need to validate that its Arabic, is it recommended to use the uni-code ranges checking, or is there a better way of doing so.
Thanks in advance

That question has been asked tons of times.
Mostly you are out of luck.
Using Unicode ranges you can check the script at best. And usually several languages share a script (many western languages share the Latin script, for example).
If you had more data about each language you need to identify (for example a complete dictionary of each language), then you could do a more in-depth analysis to find out which language it probably is. This can get hard (and even impossible) if the text you need to identify is short (just guess in how many languages "a" is a valid word).

Appreciated for our help............
Thanks a lot in advance...............

Hi Paulo,
Thanks for the reply. However i have the following setting and it still does not work..
Mapping -> AB01
When i do the simulation it shows the Number and the hits and mapping.
In the Seach String use i have following settings:
CC 1000
Interpretation : ALL Interpretation
Search String : TEST1 ( this is the name that i gave to above search string)
Target : Posting RUle
Active checked.
But still when i upload the bank statement it is posting to Rule AB03 and not AB01
Also when i try FEBSTS it says no document hits ???
Your answer is greatly appreciated.

Can i turn a series of integers such as 1000-1200 into a string to check

"Host String" to check install

Do I enter the SID into the host string to test install?
On my server (Oracle 8i for Netware) in tnsnames.ora, I have a service variable and a SID. On my client (Oracle 8i for NT),in tnsnames.ora, I have a service variable and a
Service Name variable.
TIA. I am very new to this.

The ability to detect the jre at the update level, as well as the ability to install a specific version are only present if the DT plugins are installed.
These plugins only exist for windows and are only part of the 6u10 (1.6.0_10) versions of java.
The javascript you show uses an undefined minimumVersion variable.
also note, you cannot use the wildcard '1.5.0*' in the call to isWebStartInstalled (which takes minimumVersion arg)
if fixed, this code would still not work as you want, since clients with 1.6.0 or later would sail straight thru and launch.
I suggest replacing isWebStartInstalled() with deployJava.versionCheck('1.5.0*') .
then on systems with the plugin installed, if no 1.5.0* version is installed, the latest 1.5.0_XX will be installed before launching the app.
(assuming the app has also <j2se version=1.5/> or equiv.)
on systems w/o plugins installed, the latest version of java will be installed, and it will be up to javaws auto download to get 1.5.0* version.
this could still have problems, especially on platforms not supporting the plugins (non-windows) , since code keeps checking for '1.5.0*', and installing only latest, so you would want to wrap install with something to prevent repeated attempts to install:
if (deployJava.versionCheck('1.6.0+') && !deployJava.isPluginInstalled()) {
---- don't do any install here - ---

String alphabetical checking / validation

Hi
I am wanting to check that a String is only composed of alphabetical characters or spaces. Is there a nice API in the JDK that I can use to check / validate this String?
Thanks

tinny wrote:
Regular expressions are the nice way to do it.
The code below will check to see if a String is composed of any combination of alphabetical characters or spaces.
String str = "Hello from me";
boolean result = Pattern.matches("[a-zA-Z ]+", str);result =trueNote that the ' ' (single white space) in your "[a-zA-Z ]" will not match tabs or other white space characters. If you also want them to match, you can use:
"[a-zA-Z\\s]+"
// \\s means (almost) any white space character

String fomart check

Hi,
I have to process a string for a specific format. Basically, need to check if it confirms to the given format.
The string I usually get is a numeric string. However might get some invalid values.
Format: "DDD.D" , where D is any digit from [0-9]
Input is String Output: boolean
"100.1" ---> true <-----
"1.123" ---->false
"-23" ----->false
"java2" ------>false
null ------->false
empty ------->false
I could check the length to be 4 and then check if dot is present with indexof at position 3 and check each character is a digit in range 0-9.
Is there any better way to do it? Using Pattern or BigDecimal?
Kindly suggest.
Thanks,
JY

Thanks paulcw. Thanks for the REGEX suggestion, its way lot better and simpler
So far, I used this ... pretty inefficient...
public boolean stringFormatCheck(String guiString) {

         if(guiString.length()!=5 || guiString.indexOf('.') != 3) return false;
         try {
                BigDecimal numericString = new BigDecimal(guiString);//digits check

Can we get Arraylist from String.Please check the code

Hi all,
I have just pasted my code over here.Can anyone of you find the solution for obtaining the Array list from the String.
For Example :
ArrayList al = new ArrayList();
al.add(new byte[2]);
al.add("2");
String stringVar = "" + (ArrayList) al;
Here I can convert the arraylist into string.But can we do he vice versa like obtaining the above arraylist from the string?If please advice me.
URGENT!!!!

cudIf you run the code you posted you will observe that the string form of the list does not contain all the information of the list: in particular the array elements are missing. It follows that the "vice versa" conversion you seek is simply not possible.
A variation on this theme is the following:import java.util.ArrayList;
public class ListEg {
    public static void main(String[] args) {
        ArrayList al = new ArrayList();
        al.add("foo");
        al.add("bar, baz");
        String stringVar = "" + (ArrayList) al;
        System.out.println(stringVar);
}If you think about the output you should be able to conclude that lists with different contents can easily have the same string form.
Just something to chew on.

Like Nodelist, but create temp String for checking

Hi,
how do I store the previous contents of the command String in the previousCommand string in the loop so that I can use my method to compare them?
for ( int i=0; i< totalTstCount; i++){
      for ( int j=0; j< totalTstCount; j++){;
           // store the previous command to comapre TSTs
           String previousCommand = command;
           if ( i == 0) {
                System.err.println("Issuing first FSI.....");
                response = sitaIssue.issueFsi(response);
           else if ( (j > 0) && (sitaIssue.isFsiRequired(previousCommand, command))) {
                System.err.println("Issuing another FSI.....");
                response = sitaIssue.issueFsi(response);
}

I don't know where you get command from in the first place, but I understand taht this is not your question. If you declare previousCommand outside the loops and then inside the loop, at the bottom, just before }, assign command to previousCommand (the assignment that is already in your code), then the previous command will be available the next time through the loop. Does this answer your question?

Search string for 3 digit check number?

For electronic bank statement,uploading file contains 3-digit check number eg;416
but in FCHI-Check lots we defined six-digit check numbers.
so system is not able match the check nos. as they are different, and auto reco is not happening.
we have gone through search strings documentation but
we dont know what to enter in search strings configuration.
Kindly help me what to enter for 3 digit check no?
Edited by: KUMAR on Dec 2, 2008 1:35 PM

You'll first need to create search strings to "find" the check numbers in the note to payee information. Then when you set up the search string use, you'll assign a mapping prefix of "000000" to format the check numbers with the leading zeros so they are 6-digits long.
To set up the search string, you'll need to look at the note to payee information at the text either before or after the check numbers. Let's say, for example, that the word "CHECK" always preceeds the check numbers in the note to payee:
CHECK 456
or
CHECK 1234
Because you have some check numbers coming through the bank statement as 3 digits and some as 4 digits, I'm thinking you'll need to set up two search strings, one with search string value "CHECK ###" and the following mapping:
C ->
H ->
E ->
C ->
K ->
->
-> #
-> #
-> #
And the second with search string "CHECK ####" and the following mapping:
C ->
H ->
E ->
C ->
K ->
->
-> #
-> #
-> #
-> #
In the search string use, you assign each search string to the relevant company code, house bank and account ID. You can also leave these fields blank, in which case the search strings will be relevant for all company codes, house banks and accounts IDs. You'll also need to populate the interpretation algorithm with the same algorithm that you assigned in the Global EBS config for the external transaction for checks. The target field should be Check-/DME Reference-/Assignment number. Fill in the mapping prefix with 000000 - and be sure to check the Active indicator. If you are on ECC 6.0, you will also have fields for external transaction and +- (these fields may also be available in ECC 5.0 - but I know they are not available in 4.7 or prior). If you see these fields, you can fill them in to further limit when the search string is used - for example, only for Negative transactions or only for Negative transactions with a particular external transaction value.
Let me know if you have any other questions.
Regards,
Shannon

java.util
Class Locale
java.lang.Object
java.util.Locale
All Implemented Interfaces:
Cloneable, Serializable
public final class Locale
extends Object
implements Cloneable, Serializable
A Locale object represents a specific geographical, political, or cultural region. An operation that requires a Locale to perform its task is called locale-sensitive and uses the Locale to tailor information for the user. For example, displaying a number is a locale-sensitive operation--the number should be formatted according to the customs/conventions of the user's native country, region, or culture.
Create a Locale object using the constructors in this class:
Locale(String language)
Locale(String language, String country)
Locale(String language, String country, String variant)
The language argument is a valid ISO Language Code. These codes are the lower-case, two-letter codes as defined by ISO-639. You can find a full list of these codes at a number of sites, such as:
http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt
The country argument is a valid ISO Country Code. These codes are the upper-case, two-letter codes as defined by ISO-3166. You can find a full list of these codes at a number of sites, such as:
http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html
The variant argument is a vendor or browser-specific code. For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX. Where there are two variants, separate them with an underscore, and put the most important one first. For example, a Traditional Spanish collation might construct a locale with parameters for language, country and variant as: "es", "ES", "Traditional_WIN".
Because a Locale object is just an identifier for a region, no validity check is performed when you construct a Locale. If you want to see whether particular resources are available for the Locale you construct, you must query those resources. For example, ask the NumberFormat for the locales it supports using its getAvailableLocales method.
Note: When you ask for a resource for a particular locale, you get back the best available match, not necessarily precisely what you asked for. For more information, look at ResourceBundle.
The Locale class provides a number of convenient constants that you can use to create Locale objects for commonly used locales. For example, the following creates a Locale object for the United States:
Locale.US
Once you've created a Locale you can query it for information about itself. Use getCountry to get the ISO Country Code and getLanguage to get the ISO Language Code. You can use getDisplayCountry to get the name of the country suitable for displaying to the user. Similarly, you can use getDisplayLanguage to get the name of the language suitable for displaying to the user. Interestingly, the getDisplayXXX methods are themselves locale-sensitive and have two versions: one that uses the default locale and one that uses the locale specified as an argument.
The Java 2 platform provides a number of classes that perform locale-sensitive operations. For example, the NumberFormat class formats numbers, currency, or percentages in a locale-sensitive manner. Classes such as NumberFormat have a number of convenience methods for creating a default object of that type. For example, the NumberFormat class provides these three convenience methods for creating a default NumberFormat object:
NumberFormat.getInstance()
NumberFormat.getCurrencyInstance()
NumberFormat.getPercentInstance()
These methods have two variants; one with an explicit locale and one without; the latter using the default locale.
NumberFormat.getInstance(myLocale)
NumberFormat.getCurrencyInstance(myLocale)
NumberFormat.getPercentInstance(myLocale)
A Locale is the mechanism for identifying the kind of object (NumberFormat) that you would like to get. The locale is just a mechanism for identifying objects, not a container for the objects themselves.
Each class that performs locale-sensitive operations allows you to get all the available objects of that type. You can sift through these objects by language, country, or variant, and use the display names to present a menu to the user. For example, you can create a menu of all the collation objects suitable for a given language. Such classes must implement these three class methods:
public static Locale[] getAvailableLocales()
public static String getDisplayName(Locale objectLocale,
Locale displayLocale)
public static final String getDisplayName(Locale objectLocale)
// getDisplayName will throw MissingResourceException if the locale
// is not one of the available locales.

Constructor Detail
Locale
public Locale(String language,
String country,
String variant)Construct a locale from language, country, variant. NOTE: ISO 639 is not a stable standard; some of the language codes it defines (specifically iw, ji, and in) have changed. This constructor accepts both the old codes (iw, ji, and in) and the new codes (he, yi, and id), but all other API on Locale will return only the OLD codes.
Parameters:
language - lowercase two-letter ISO-639 code.
country - uppercase two-letter ISO-3166 code.
variant - vendor and browser specific code. See class description.
Throws:
NullPointerException - thrown if any argument is null.
Locale

This constructor accepts both the old codes (iw, ji, and in) and the new codes (he, yi, and id), but all other API on Locale will return only the OLD codes.
Parameters:
language - lowercase two-letter ISO-639 code.
country - uppercase two-letter ISO-3166 code.
Throws:
NullPointerException - thrown if either argument is null.

Method Detail
getDefault
public static Locale getDefault()Gets the current value of the default locale for this instance of the Java Virtual Machine.
The Java Virtual Machine sets the default locale during startup based on the host environment. It is used by many locale-sensitive methods if no locale is explicitly specified. It can be changed using the setDefault method.
Returns:
the default locale for this instance of the Java Virtual Machine
setDefault
public static void setDefault(Locale newLocale)Sets the default locale for this instance of the Java Virtual Machine. This does not affect the host locale.
If there is a security manager, its checkPermission method is called with a PropertyPermission("user.language", "write") permission before the default locale is changed.
The Java Virtual Machine sets the default locale during startup based on the host environment. It is used by many locale-sensitive methods if no locale is explicitly specified.
Since changing the default locale may affect many different areas of functionality, this method should only be used if the caller is prepared to reinitialize locale-sensitive code running within the same Java Virtual Machine, such as the user interface.
Parameters:
newLocale - the new default locale
Throws:
SecurityException - if a security manager exists and its checkPermission method doesn't allow the operation.
NullPointerException - if newLocale is null

SecurityManager.checkPermission(java.security.Permission), PropertyPermission
getAvailableLocales
public static Locale[] getAvailableLocales()Returns a list of all installed locales.
getISOCountries
public static String[] getISOCountries()Returns a list of all 2-letter country codes defined in ISO 3166. Can be used to create Locales.
getISOLanguages
public static String[] getISOLanguages()Returns a list of all 2-letter language codes defined in ISO 639. Can be used to create Locales. [NOTE: ISO 639 is not a stable standard-- some languages' codes have changed. The list this function returns includes both the new and the old codes for the languages whose codes have changed.]
getLanguage
public String getLanguage()Returns the language code for this locale, which will either be the empty string or a lowercase ISO 639 code.
NOTE: ISO 639 is not a stable standard-- some languages' codes have changed. Locale's constructor recognizes both the new and the old codes for the languages whose codes have changed, but this function always returns the old code. If you want to check for a specific language whose code has changed, don't do
if (locale.getLanguage().equals("he")
Instead, do
if (locale.getLanguage().equals(new Locale("he", "", "").getLanguage())

getDisplayLanguage()
getCountry
public String getCountry()Returns the country/region code for this locale, which will either be the empty string or an upercase ISO 3166 2-letter code.
See Also:

getVariant
public String getVariant()Returns the variant code for this locale.
See Also:
getDisplayVariant()
toString
public final String toString()Getter for the programmatic name of the entire locale, with the language, country and variant separated by underbars. Language is always lower case, and country is always upper case. If the language is missing, the string will begin with an underbar. If both the language and country fields are missing, this function will return the empty string, even if the variant field is filled in (you can't have a locale with just a variant-- the variant must accompany a valid language or country code). Examples: "en", "de_DE", "_GB", "en_US_WIN", "de__POSIX", "fr__MAC"
Overrides:
toString in class Object
Returns:
a string representation of the object.

getDisplayName()
getISO3Language
public String getISO3Language()
throws MissingResourceExceptionReturns a three-letter abbreviation for this locale's language. If the locale doesn't specify a language, this will be the empty string. Otherwise, this will be a lowercase ISO 639-2/T language code. The ISO 639-2 language codes can be found on-line at ftp://dkuug.dk/i18n/iso-639-2.txt
Throws:
MissingResourceException - Throws MissingResourceException if the three-letter language abbreviation is not available for this locale.

throws MissingResourceExceptionReturns a three-letter abbreviation for this locale's country. If the locale doesn't specify a country, this will be tbe the empty string. Otherwise, this will be an uppercase ISO 3166 3-letter country code.
Throws:
MissingResourceException - Throws MissingResourceException if the three-letter country abbreviation is not available for this locale.
getDisplayLanguage
public final String getDisplayLanguage()Returns a name for the locale's language that is appropriate for display to the user. If possible, the name returned will be localized for the default locale. For example, if the locale is fr_FR and the default locale is en_US, getDisplayLanguage() will return "French"; if the locale is en_US and the default locale is fr_FR, getDisplayLanguage() will return "anglais". If the name returned cannot be localized for the default locale, (say, we don't have a Japanese name for Croatian), this function falls back on the English name, and uses the ISO code as a last-resort value. If the locale doesn't specify a language, this function returns the empty string.
getDisplayLanguage
public String getDisplayLanguage(Locale inLocale)Returns a name for the locale's language that is appropriate for display to the user. If possible, the name returned will be localized according to inLocale. For example, if the locale is fr_FR and inLocale is en_US, getDisplayLanguage() will return "French"; if the locale is en_US and inLocale is fr_FR, getDisplayLanguage() will return "anglais". If the name returned cannot be localized according to inLocale, (say, we don't have a Japanese name for Croatian), this function falls back on the default locale, on the English name, and finally on the ISO code as a last-resort value. If the locale doesn't specify a language, this function returns the empty string.

If the name returned cannot be localized for the default locale, (say, we don't have a Japanese name for Croatia), this function falls back on the English name, and uses the ISO code as a last-resort value. If the locale doesn't specify a country, this function returns the empty string.

getDisplayVariant
public final String getDisplayVariant()Returns a name for the locale's variant code that is appropriate for display to the user. If possible, the name will be localized for the default locale. If the locale doesn't specify a variant code, this function returns the empty string.
getDisplayVariant
public String getDisplayVariant(Locale inLocale)Returns a name for the locale's variant code that is appropriate for display to the user. If possible, the name will be localized for inLocale. If the locale doesn't specify a variant code, this function returns the empty string.
getDisplayName
public final String getDisplayName()Returns a name for the locale that is appropriate for display to the user. This will be the values returned by getDisplayLanguage(), getDisplayCountry(), and getDisplayVariant() assembled into a single string. The display name will have one of the following forms:
language (country, variant)
language (country)
language (variant)
country (variant)
language
country
variant
depending on which fields are specified in the locale. If the language, country, and variant fields are all empty, this function returns the empty string.

Was it really necessary to post the whole API description?!?
Locale[] locales = Locale.ENGLISH();ENGLISH is not a method in class Locale, so do not add the braces "( );".
Also, the constant ENGLISH is not an array, but just a single Locale object.
You didn't say what your problem was. What do you want to achieve with your program and what is it that you don't understand?

Is there Java support for Indian languages other than Hindi?

I'd like to use Tamil as a test language for some translated java files.
I don't know whether it is supported or not.
Alternatives are Bangla, Gujararati, Kannada, Marathi, Oriya, Punjabi, Telugu. Are any of these supported?
I'd prefer not to use Hindi.
The only website I can find listing the languages supported is from 2003. If you have a link to a more recent one, I would appreciate it.

Locale is basically a glorified String[], so the idea that some locales are supported and others are not is sort of illusory.
Quoting from the API...
[quote begins]
Locale(String language, String country, String variant)
The language argument is a valid ISO Language Code. These codes are the lower-case, two-letter codes as defined by ISO-639... The country argument is a valid ISO Country Code. These codes are the upper-case, two-letter codes as defined by ISO-3166...
Because a Locale object is just an identifier for a region, no validity check is performed when you construct a Locale...
The Locale class provides a number of convenient constants that you can use to create Locale objects for commonly used locales...
A Locale is the mechanism for identifying the kind of object (NumberFormat) that you would like to get. The locale is just a mechanism for identifying objects, not a container for the objects themselves.
[quote ends]
In other words, if you wanted to make up your own local for the language that they speak on Planet X (Xian), you could perfectly well have a Local object for that and properties or list files for it.

But i have even checked the syntax of encode at which is exactly matching
http://java.sun.com/j2se/1.4.2/docs/api/java/net/URLEncoder.html
Kindly let me know what is the reason.......

Check the Java API for this:
There is a specific note for the method, which reads as follows:
Note: The World Wide Web Consortium Recommendation states that UTF-8 should be used. Not doing so may introduce incompatibilites.
It's always better to look in API docs.

From MD5-string to byte array

Hi fellows, I'm writing a simple cracker for MD5. The hash value has to be passed at command line as argument.
e.g.
java Cracker 0cc175b9c0f1b6a831c399e269772661In order to decode the hash value I'm using a brute force approach: therefore I compare a series of strings with the hash value by using the method of the class MessageDigest isEqual(byte[] a, byte[] b). So I encode each string and compare the byte array I get with the byte array of the hash value.
Here it comes the trouble I'm in:
when I try to get a bytes array of the MD5 hash value passed as argument of the program , I do get something, but it's not something that the isEqual method of MessageDigest can use to compare. As a result any attempt during the execution of brute force fails, even though the key is one of the string being checked.
Perhaps am I facing a format problem? Any idea?
Sorry for my english, it's not my first language
Thanks to whoever will help

Almost all questions in these forums about brute force attack on MD5 (or SHA1 or SHA256 etc etc etc) are school, college or university projects and of no practical use. This is almost certainly such a project.
Unless things have changed in the last year, there is no practical brute force attack on MD5 whereby an input can be generated from an arbitrary output even though two inputs with the same output can be fabricated. A dictionary attack is feasible if no salt is used or a known salt is used since one only has to build the dictionary for one salt value. If a different salt is used for each entry being attacked then a dictionary will be need for each salt being used. Of course if one takes the simple precaution of not using anything that is likely to be in a dictionary then the dictionary attack will likely fail.

Portal Language through code

Hi,
I currently have the following code to check the language of a user within Portal, but when the user has no language populated I would like to set this to a default. How can I check the value as when I have coded this before this has errored.
IUser me = request.getUser();
String language = "en";
Locale myLocale = me.getLocale();
language = myLocale.getLanguage();
try {
IUserMaint modUser = userFact.getMutableUser(me.getUid());
if (language.equalsIgnoreCase(""))
     modUser.setLocale(Locale.UK);
if (language.equalsIgnoreCase("english"))
     modUser.setLocale(Locale.UK);
if (language.equalsIgnoreCase("italian"))
     modUser.setLocale(Locale.ITALIAN);
if (language.equalsIgnoreCase("german"))
     modUser.setLocale(Locale.GERMAN);
modUser.commit();
modUser.save();
catch (Exception e) {
     response.write("<br>Problem setting language: "+e.getMessage());
     oksofar = false;
Any help would gratefully appreciated.

Hi Kai,
> when I have coded this before this has errored
Are you talking about the code snippet given? If yes, what kind of error?!?!
> when the user has no language populated I would like to set this to a default
If that what you want to try with the code snippet given? The snippet is (a) wrong and (b) strange:
a) Wrong. locale.getLanguage never returns "english" or "italian" or "geman"; it returns the language code (a lowercase ISO 639 code).
b) Strange. You want to check if it is set to "german" and then you set it to german?! Don't understand your logic...
You should also call save() first and then commit(); see http://help.sap.com/javadocs/nw04s/current/se/com/sap/security/api/IPrincipalMaint.html#save()
Also, keep in mind that you cannot change the locale of a user if this attribute would be mapped to some LDAP attribute and if the LDAP is connected read-only.
Hope it helps
