Replacing characters in strings

I created a string using-
String a = "c:\test\"I would like to be able to go through this string and replace all backslashes with double backslashes. I am having problems doing this because Java sees backslashes as the begining of an escape character.
Does anyone have any idea how I could work around this problem?

Why don't you escape the backslashes initially...
aka
String a = "c:\\test\\";
Because I really didn't create that string, I just said I did to give you an example of what im want to do, I am actually getting the string back from file.getPath()
However, I'd first question why you think you need to
specify platform-specific directory separators, when
Java will be happy with the platform-agnostic "/"
directory separator and handle the translation for
you.Getting the path of file will return back slashes. I need to change that to double backslases to use place it in getRuntime().exec() or it will have it's own escape character problems.
What I wan't to use it for is not really the issue, im just having a problem with relacing backslashes with double backslashes in a string.

Problem in replacing characters of a string ?

Hello everybody,
I want to replace a few characters with their corresponding unicode codepoint values.
I have a userdefined method that gets the unicode codepoint value for a character.
1. I want to know how to replace the characters and have the replaced string after the comparision is over in the for loop in my main.
Currently , i am able to replace , but i am not able to have the replacements done in a single variable.
The output of the code is
e\u3006ame
ena\u3005e
But i want the output i require is,
e\u3006a\u3005e
Please offer some help in this regard

This manual replacement thingy reminds me of quite an old technique, when
64KB of memory was considered enough for 20 users (at the same time that is!)
Suppose you have a buffer of, say, n characters. Starting at location i, a region
of chars have to be swapped with bytes starting at location j >= i+l_i; the lengths
of the two regions are l_i and l_j respectively.
Suppose the following method is available:public void reverse(char[] buffer, int f, int l_f) {
   for (int t= f+l_f; --t > f; f++) {
      char tmp=buffer[f]; buffer[f]= buffer[t]; buffer[t]= tmp;
}i.e. the above method reverses a region of characters, starting at position f
with length l_f. Given this simple method, the original problem can be solved
using the following simple sequence:reverse(buffer, i, j+l_j);
reverse(buffer, i, l_j);
reverse(buffer, i+l_j, j-i-l_i);
reverse(buffer, j+l_j-l_i, l_i);Of course, when replacing characters we don't need the last reversal.

Replace special characters in String

Dear Guru ,
Does SAP provide the standard function that can replace the special characters in String ?
For example :
I have one template string : " & & & & & output(s) have not been processed yet ! " and five parameters : "P1" , "P2" , "P3" , "P4" , "P5" .
And i would like to apply all parameters into the string to replace the "&" character . Is it possibile ?
My idea is sourcing from the Message String that in tcode : SE91 .
Thanks .
Best Regards,
Carlos Zhang

Hi Carlos,
I think instead of a standard FM you can write a one line command to do this job.
E.g.
constant: str1 type string value 'output(s) have not been processed yet ! '.
data: var1 type c,
         var2 type c,
         var3 type c,
         var4 type c,
         str    type string.
concatenate var1 var2 var3 var4 str1 into str separated by space.
So str will have the final value.
Thanks,
Mainak

Removing non-numeric characters from string

Hi there,
I need to have the ability to remove non-numeric characters from a string and I do not know how to do this.
Does any one know a way?
Example:
Present String: (02)-2345-4607
Required String: 0223454607
Thanks in advance

Dear NickM
Try this this will work...........
create or replace function char2num(mstring in varchar2) return integer
is
-- Function to remove Special characters and alphebets from phone no. string field
-- Author - Valid Bharde.(India-Mumbai)
-- Date :- 20 Sept 2006.
-- This Function will return numeric representation.
-- The Folowing program is gifted to NickM with respect to his post on oracle site regarding Removing non-numeric characters from string on the said date
mstatus number :=0;
mnum number:=0;
mrefstring varchar2(50);
begin
mnum := length(mstring);
for x in 1..mnum loop
if (ASCII(substr(upper(mstring),x,1)) >= 48 and ASCII(substr(upper(mstring),x,1)) <= 57) then
mrefstring := mrefstring || substr(mstring,x,1);
end if;
end loop;
return mrefstring;
end;
copy the above program and use it at function for example
SQL> select char2num('(022)-453452781') from dual;
CHAR2NUM('(022)-453452781')
22453452781

Search given string array and replace with another string array using Regex

Hi All,
I want to search the given string array and replace with another string array using regex in java
for example,
String news = "If you wish to search for any of these characters, they must be preceded by the character to be interpreted"
String fromValue[] = {"you", "search", "for", "any"}
String toValue[] = {"me", "dont search", "never", "trip"}
so the string "you" needs to be converted to "me" i.e you --> me. Similarly
you --> me
search --> don't search
for --> never
any --> trip
I want a SINGLE Regular Expression with search and replaces and returns a SINGLE String after replacing all.
I don't like to iterate one by one and applying regex for each from and to value. Instead i want to iterate the array and form a SINGLE Regulare expression and use to replace the contents of the Entire String.
One Single regular expression which matches the pattern and solve the issue.
the output should be as:
If me wish to don't search never trip etc...,
Please help me to resolve this.
Thanks In Advance,
Kathir

As stated, no, it can't be done. But that doesn't mean you have to make a separate pass over the input for each word you want to replace. You can employ a regex that matches any word, then use the lower-level Matcher methods to replace the word or not depending on what was matched. Here's an example: import java.util.*;
import java.util.regex.*;
public class Test
static final List<String> oldWords =
      Arrays.asList("you", "search", "for", "any");
static final List<String> newWords =
      Arrays.asList("me", "dont search", "never", "trip");
public static void main(String[] args) throws Exception
    String str = "If you wish to search for any of these characters, "
        + "they must be preceded by the character to be interpreted";
    System.out.println(doReplace(str));
public static String doReplace(String str)
    Pattern p = Pattern.compile("\\b\\w+\\b");
    Matcher m = p.matcher(str);
    StringBuffer sb = new StringBuffer();
    while (m.find())
      int pos = oldWords.indexOf(m.group());
      if (pos > -1)
        m.appendReplacement(sb, "");
        sb.append(newWords.get(pos));
    m.appendTail(sb);
    return sb.toString();
} This is just a demonstration of the technique; a real-world solution would require a more complicated regex, and I would probably use a Map instead of the two Lists (or arrays).

TIA,

Is there no place to track the status of the report or see any other outstanding issues so I don't bother filing duplicates?
Never heard of such a function here. This method gets feedback to the people who count but it is completely behind the scenes. Part of Apple's "cards close to the chest" method of doing pretty much everything. You should have been looking at the "don't expect a response" screen after you hit the submit button on your bug report.
If there is something that needs clarification, I suspect they will use e-mail to ask for it, but don't stay home waiting!

How Can I replace newScale Text Strings with Custom Values?

How Can I replace newScale Text Strings with Custom Values?
How can I replace newScale text strings with custom values?
All newScale text is customizable. Follow the procedure below to change the value of any text string that appears in RequestCenter online pages.
Procedure
1. Find out the String ID of the text string you would like to overwrite by turning on the String ID display:
a) Navigate to the RequestCenter.ear/config directory.
b) Open the newscale.properties file and add the following name-value pair at the end of the file:res.format=2
c) Save the file.
d) Repeat steps b and c for the RmiConfig.prop and RequestCenter.prop files.
e) Stop and restart the RequestCenter service.
f) Log in to RequestCenter and browse to the page that has the text you want to overwrite. In front of the text you will now see the String ID.
g) Note down the String ID's you want to change.
2. Navigate to the directory: /RequestCenter.ear/RequestCenter.war/WEB-INF/classes/com/newscale/bfw.
3. Create the following sub-directory: res/resources
4. Create the following empty text files in the directory you just created:
RequestCenter_0.properties
RequestCenter_1.properties
RequestCenter_2.properties
RequestCenter_3.properties
RequestCenter_4.properties
RequestCenter_5.properties
RequestCenter_6.properties
RequestCenter_7.properties
5. Add the custom text strings to the appropriate RequestCenter_<Number>.properties file in the following manner (name-value pair) StringID=YourCustomTextString
Example: The StringID for "Available Work" in ServiceManager is 699.
If you wanted to change "Available Work" to "General Inbox", you would add the following line to the RequestCenter_0.properties file
699=General Inbox
Strings are divided into the following files, based on their numeric ID:
Strings are divided into the following files, based on their numeric ID:
String ID File Name
0 to 999 -> RequestCenter_0.properties
1000 to 1999 -> RequestCenter_1.properties
2000 to 2999 -> RequestCenter_2.properties
3000 to 3999 -> RequestCenter_3.properties
4000 to 4999 -> RequestCenter_4.properties
5000 to 5999 -> RequestCenter_5.properties
6000 to 6999 -> RequestCenter_6.properties
7000 to 7999 -> RequestCenter_7.properties
6. Turn off the String ID display by removing (or commenting out) the line "res.format=2" from the newscale.properties, RequestCenter.prop and RmiConfig.prop files
7. Restart RequestCenter.
Your customized text should be displayed.

I've recently come across this information and it was very helpful in changing some of the inline text.
However, one place that seemed out of reach with this method was the three main buttons on an "Order" page. Specifically the "Add & Review Order" button was confusing some of our users.
Through the use of JavaScript we were able to modify the label of this button. We placed JS in the footer.html file that changes the value of the butt

Characters in String : Unicode 16-bit to custom 32-bit

I understand that internally in Java, characters in Strings are actually Unicode characters, with each character represented with 16 bits.
So, character �L� in Unicode is 0x004C
which is also 0000 0000 0100 1100
Now, I wish to encode each of the 4 bits above into individual ASCII characters:
= 0 0 4 C
= 0x30 0x30 0x34 0x43
= 00110000 00110000 00110100 01000011
So, from the original 16-bit character in Java, I want a final 32-bit.
Eventually, I�ll need to send the final result over the network, via OutputStream/writer and socket.
Can someone help me on this ? Or give me some ideas... Thanks.

trick: prepend the number with 1 and use substring... like int charWith1 = c + 0x10000. That'll make charWith1 to be of the format 0x1XXXX. Then call hexstring on that, you get a string like "1XXXX." Then you can drop the 1 with a call to substring.
of course there are methods that use only bit operations and additions to do it, making it a bit faster.. like this:
byte byte0 = (byte) ((c & 0x000F) + '0');
byte byte1 = (byte) (((c & 0x00F0) >> 4) + '0');

Replace charcter from string in 46c

Hi,

hi check the replace statement... hit F1 on replace and make ur code..
Basic form
REPLACE f WITH g INTO h.
Addition
... LENGTH len (length specification for field f )
Effect
Replaces the first occurrence of the contents of field f in field h with the contents of field g . All fields are handled in their defined length; this means that closing blanks are not ignored.
The return code value indicates whether the string f was found in h and replaced by g :
SY-SUBRC = 0 String replaced.
SY_SUBRC = 4 String not replaced.
Example
    DATA FIELD(10).
    MOVE 'ABCB' TO FIELD.
    REPLACE 'B' WITH 'string' INTO FIELD.
returns:
FIELD = 'AstringCB', SY-SUBRC = 0
Note
The fields f and g in the REPLACE statement should not overlap. Otherwise, the result is undefined.
Addition
... LENGTH len ... (length specification for field f )
Effect
Searches for the string f in the field h not in its (full) field length, but in the length len .
Example
    DATA: PATTERN(5) VALUE 'ABC',
          LEN TYPE I,
          REPL_STRING(5) VALUE '12345',
          FIELD(12) VALUE 'abcdeABCDE'.
    REPLACE PATTERN WITH REPL_STRING
                    INTO FIELD.
does not change FIELD , since 'ABC ' does not occur in abcdeABCDE ' .
    LEN = STRLEN( PATTERN ).
    REPLACE PATTERN LENGTH LEN
                    WITH REPL_STRING
                    INTO FIELD.

How to replace mixed chars string

Hi All,
I want to replace mixed chars string from each row and want to replace with new string.
Ex : The existing string might be in different cases like "Abc string", "abc string", "aBC string". I want to search for all these string types and want to replace with new string "Abc string".
Could anyone give suggestions on this.
Thanks,
