Best way of compaing strings

Hi All
Consider i have a properties file abc.properties in which there is property key (PROPKEY1) values are delimited by semicolun
PROPKEY1 = and;in;on;by;to
In my code based on some validation i get a string whose value is some what like this
String name = "Jacob;abl;mon;sandra"
Goal is to find out whether the name(above) contains anything one value("and" or "in" or "by" or "to") from the property file
I know one way of day is iterting each of them and comparing them.
But there should be a better way to do it. Please help me on this.
Thanks in advance

But there should be a better way to do it. Please help me on this.Do what EJP said. String.split() should help you create the String Sets he suggests.
You might also want to have a look at the Properties class. Extending it might be a quick way way to create what you want; alternatively, you could use it as an interim Map<String, String>.

Please Suggest best way to pass Strings in a pipeline

I'm working in a project in which a line passes in a pipeline kind of situation.
The String is passed between different modules and each module adds some more data to it (or may even remove some of it).
Which is the best way to pass the String? I think java.lang.String might not be an efficient method because the String i'll be passing will be modified many times.
Thanx

Yes. StringBuffer or StringBuilder you can use.
String string = "test";
StringBuffer sb = new StringBuffer(string);later you will add some more strings to the StringBuffer
sb.append("Hello World");No additiional String object will be created.

Best way to store string resources for localization?

My midlet has alot of string resources that I want to be able to easily customize, and I wonder what is the best way to do this using J2ME? To make the code easy to localize I would like all strings to reside in a single file (either a class file or a file system file). It doesnt seem that there is an easy way to do this (eg a "resource file" or some such). Do I just need to create a class that defines a bunch of static final String objects?
Thx,
Fred

Best way to extract strings

Hello,
I need to extract the value of the strings for REQUEST_GROUP_CODE and REQUEST_GROUP_APPL_SHORT_NAME. As you can see I have to deal with whitespace differences, case differences etc. I need the values between the quotes for each one. I would expect to get ACCOUNTING and AR for the first example. I am using db version 11g r1.
Thanks.

Basic easy noob question - best way of getting string from slider value

Hi all
I'm using a slider in my iPhone app to allow the user to select the number of days on a scale 1 - 10 for example.
I've got the following which isn't quite working and after battling for hours and hours to get my head around UINavigationControllers I really can't be bothered anymore. Can someone please just give me the answer
I want to get an int value from the slider which returns a float. here's my code I have (which again, isn't working correctly).
-(IBAction)numberofDaysSliderMoved:(id)sender {
NSNumber *theValue = [NSNumber numberWithFloat:numberofDaysSlider.value];
[myLabel setText:[numberFormatter stringFromNumber:theValue]];
I know it's crap code and i've probably coded the long way round but i'm just trying to get it working and i'm new to obj-C so please bare with me.
Regards
Wayne

First off - you can wrap your code here like this:
my code here
<-- no slash
Here you go:
NSNumber *sliderValue = [NSNumber numberWithFloat:numberofDaysSlider.value];
int intValue = [sliderValue intValue];
NSString *stringValue = [sliderValue stringValue];
Have a look as the NSNumber docs. Lots of easy ways to create and convert numbers.

What is the best way of converting everything in a result set into a string

hello folks
What do you think is the best way of converting everything in a resultset into a string???
At the moment I'm using
rs.getString(i);
everywhere (no matter if the underlying datatype is a date or whatever..) it converts automatically evertything expect NULL into a valid string.
Are there better (simple to use..) ways?

I don't see a big switch construct. How about trying the following:
Call this method from your original method by passing the resultset obtained.
public String[] convert(ResultSet rs) {
     int col = ((ResultSetMetaData) rs.getMetaData()).getColumnCount();
     String[] record = new String[col];
     int i=0;
     while(rs.next()) {
          if(rs.wasNull()) record[i] = new String();
          else record[i] = rs.getString(i);
          i++;
     return record;

The Best Way to Assign an Enum to the Corresponds value of a String?

I am reading from and xml file configuration file. The data being returned is stored as a String and corresponds to a Enum value. My question is - What is the best way to assign the enum the value that corresponds to value of the string?
public enum Names { BOB, FRED, JIM, SAM }
String name = "FRED"; // This is the data retuned from the xml file.
Names n = // I want to assign n the value of Names.FREDI know I could do an "if" statement. However, this is a contrived example with only a few enum values. In the real world, this enum list could be quite large.
I have looked into reflection, but I don't know whether there is an easier way to achieve my objective?
Thank you for your time,
Harold Clements

But for looking up "how do I do X with a subclass of type Y", I think the API documentation should be able to answer that.I think I disagree when it's a language feature.That's definitely a point worth observing.
By that reasoning you'd expect to populate the API docs with definitions for class (and this and super) all over the place.I think you're exaggerate, and you know it ;-)
If those were to be mentioned in the JavaDoc, they should obviously go into the documentation of java.lang.Object only.
I suppose you could have a "synthetics" section to the docs in much the same way that the inherited methods and fields are defined but it doesn't seem very useful.It's not useful if it's just clutter that's the same everywhere, of course.
But in this particular case a simple "note that enum classes have a syntetic valueOf() method that does foo bar baz" in the body of the class documentation would have been a nice guesture (especially since that part is pretty small here anyway).
And yes, I also think that the length field of arrays should find some mention in the JavaDoc. I don't know how and where, 'though.

Best way to split a single string containing 2 words into word1 and word2

Whats the best way to take a string containing 2 words and split it into 2 strings ?
eg. "red ferrari"
string1 "red"
string2 "ferrari"

If your list is always going to have exactly two words, then yes. Otherwise it depends on your requierments.

Best Way to Enumerate a non-unique Array of String to Integers

Hello,
I am trying to find the best way to enumerate an array of strings to integers. This string array is thousands in number and contains non-unique values.
I also don't know before run-time what those values are, so I have to dynamically determine the enumeration.
For example a user reads in an array of colors (but we didnt know this before runtime) of "red", "green", "red", "blue", "white", "green", "black", "blue"
I would like this to enumerate to 0, 1, 0, 2, 3, 1, 4, 2
as zero based enumeration.
Is there any suggested methods of doing this as efficiently on SPEED over MEMORY as possible?
Thanks!
Glenn

I also don't know before run-time what those values are, so I have to dynamically determine the enumeration.Are you saying that you can't pre-define the universe of colors that a user could potentially enter? If so, how will you determine the equivalence of RED to 0, etc? That sounds suspicious, there is a finite number of colors!
Anyway, for what it's worth, here's some code (that requires you know the color labels that could be entered.)
enum Color
    RED(0), GREEN(1), BLUE(2), BLACK(3), WHITE(4);
    private final int colorValue;
    private Color(int colorValue)
        this.colorValue = colorValue;
    public int getColorValue()
        return colorValue;
public class EnumTest
    public static void main(String[] args)
        System.out.println(Color.RED + " = " + Color.RED.getColorValue());
        System.out.println(Color.GREEN + " = " + Color.GREEN.getColorValue());
        System.out.println(Color.BLUE + " = " + Color.BLUE.getColorValue());
        System.out.println(Color.BLACK + " = " + Color.BLACK.getColorValue());
        System.out.println(Color.WHITE + " = " + Color.WHITE.getColorValue());
}

Best way to remove unwanted signs from string

Which is the best way to purify a string from possible dangerous signs? I want to remove all characters that is not a-z or 0-9? how would I go about?

read the string character by character, and check to
see if they're characters you want to remove or not,
by comparing them to the ascii values of characters
you permit. I've used this before, but I can't
remember what exactly it permits, and I'm too lazy to
look up the ascii table :) But this sort of thing
works.
int c = in.read();
while(c!=-1){
if((c<33)||(c<58&&c>44)){
out.write(c);
I thought about that too. But the values in the ASCII table... arn't they a little volatile to use? I mean, will my application work on other systems or systems with other languages?

Remove at "space" of a string? How the best way to remove it???

I get a string
e.g:
string s="a b c d s c s g w".
I want as results:
e.g:
string s="a b c d s c s g w".
How the best way to remove it??? I don't want that (value.Split(" ","")).

You could use regex as follows:
System.Text.RegularExpressions.Regex.Replace(yourString, " +", " ")

Best Way to Check for same Word in string?

If I have an array of words, would the best way to check for the same word be to use 2 for loops?

Huh?
Sounds like homework...
What is a word? Presumably a String.
For equality of Strings you use...
    String s1 = ....
    String s2 =....
    if (s1 == s2) { equal depending on null case
    else if ((s1 != null) && (s1.equals(s2))) { equal }
For the case of checking one array to another....
      while items in array1
             get itema from array1
                  while items in array2
                       get itemb array2
                              is itemb equal (see above) to itema
                                     yes - then do something

Best way to look for next char in String that is NOT "-" or " " or ","?

I have a long String that is sent to me and needs to be parsed. Normally I can figure the end of the line by a line break, but sometimes the line break is lost only after the second line. This second line contains the characters:
These characters can all appear any number of times. I will know I'm at the end of the line when I hit a character that is not one of those three. What is the best way to look for this? Is there an already set method in the Java API?
Thanks for all the help!

There are solutions using regular expression, eg; you can split string once a time using minus char, whitespace or comma:
String tokens[] = anyString.split("\\-|\\x20|,");
More sophisticated expressions could be done to achieve results:
String re = "^(.+)(\\-|\\x20|,)(.)(.*)$";
Matcher m = Pattern.compile(re).matcher(anyString);
if (m.matches()) {
String
before = m.group(1),
delimiter = m.group(2),
firstCharAfterDelimiter = m.group(3),
suffix = m.group(4);

Best way to break down a string?

Hi.
I am wondering, what is the best way to get all the substrings with a patten from a string.
Here is an example.
String str = "|hello|123456|a,b,c,d,e,|"
i want to get all the substrings between 2 consecutive "|" symbols.
hello
123456
a,b,c,d,e,
is there a build in method to achieve it? Read it char by char is the only way?
what do you think is most efficient way of doing it?

what do you think is most efficient way of doing it?i would use the substring command and look for the index's of the characters you wan't it saves a lot of space compared to the charAt command.. something kinda like this(you prob need to fix it up some)
)String str = "|hello|123456|a,b,c,d,e,|"
int index = 0
while (front < str.LastindexOf("|")
      frontindex = str.indexOf("|",front)
      backindex = str.indexOf("|",front+1)
      newstr[index] = str.substring (front, back)
index++
}
