Split/remove characters for a string token

How can a string token i.e. 2-234-56723-4 have the - removed so that the token is left with 2234567234?
I tried to split it using "-" but that obviously doesnt work, because 234 will be a token, I just want to remove the - from the token.
advice please.

String someStr = "3-34-565456-4";
String numsOnly = someStr.replaceAll("-", ""); //or someStr.replaceAll("[^0-9]", "");
for ( char c : numsOnly.toCharArray() ) {
int digit = c - '0';
}Or
for ( int i = 0; i < numsOnly.length(); i++ ) {
int digit = Integer.parseInt(numsOnly.substring(i, i+1));
What is "digit" ? and doesn't it re-assign a new number to digit each iteration?
Im not sure how I will access each digit.

Remove characters in a string

wondering.. anyone knows how to remove characters in a string
e.g.
string: applepie
after removing last 3 chars become "apple"
thanks...

That of course will only work for this example. Better solution is to use indexOf() to locate the position of the string you wish to remove. If the string you wish to remove is in the middle, then you will have to do a bit of extra work and concat two substrings.

Removing characters from a String (concats, substrings, etc)

This has got me pretty stumped.
I'm creating a class which takes in a string and then returns the string without vowels and without even numbers. Vowels and even characters are considered "invalid." As an example:
Input: "hello 123"
Output: "hll 13"
The output is the "valid" form of the string.
Within my class, I have various methods set up, one of which determines if a particular character is "valid" or not, and it is working fine. My problem is that I can't figure out how to essentially "erase" the invalid characters from the string. I have been trying to work with substrings and the concat method, but I can't seem to get it to do what I want. I either get an OutOfBoundsException throw, or I get a cut-up string that just isn't quite right. One time I got the method to work with "hello" (it returned "hll") but when I modified the string the method stopped working again.
Here's what I have at the moment. It doesn't work properly for all strings, but it should give you an idea of where i'm going with it.
public String getValidString(){
          String valid = str;
          int start = 0;
          for(int i=0; i<=valid.length()-1; i++){
               if(isValid(valid.charAt(i))==false){
                         String sub1 = valid.substring(start, i);
                         while(isValid(valid.charAt(i))==false)
                              i++;
                         start=i;
                         String sub2 = valid.substring(i, valid.length()-1);
                         valid = sub1.concat(sub2);
          return valid;
     }So does anybody have any advice for me or know how I can get this to work?
Thanks a lot.

Thansk for the suggestions so far, but i'm not sure how to implement some of them into my program. I probably wasn't specific enough about what all I have.
I have two classes. One is NoVowelNoEven which contains the code for handling the string. The other is simply a test class, which has my main() method, used for running the program.
Here's my class and what's involved:
public class NoVowelNoEven {
//data fields
     private String str;
//constructors
     NoVowelNoEven(){
          str="hello";
     NoVowelNoEven(String string){
          str=string;
//methods
     public String getOriginal(){
          return str;
     public String getValidString(){
          String valid = str;
          int start = 0;
          for(int i=0; i<=valid.length()-1; i++){
               if(isValid(valid.charAt(i))==false){
                         String sub1 = valid.substring(start, i);
                         while(isValid(valid.charAt(i))==false)
                              i++;
                         start=i;
                         String sub2 = valid.substring(i, valid.length()-1);
                         valid = sub1.concat(sub2);
          return valid;
     public static int countValidChar(String string){
          int valid=string.length();
          for(int i=0; i<=string.length()-1; i++){
               if(isNumber(string.charAt(i))==false){
                    if((upperVowel(string.charAt(i))==true)||lowerVowel(string.charAt(i))){
                         valid--;}
               else if(even(string.charAt(i))==true)
                    valid--;
          return valid;
     private static boolean even(char num){
          boolean even=false;
          int test=(int)num-48;
          if(test%2==0)
               even=true;
          return even;
     private static boolean isNumber(char chara){
          boolean number=false;
          for(int i=0; i<=9; i++){
               if((int)chara-48==i){
                    number=true;
          return number;
     private static boolean isValid(char chara){
          boolean valid=true;
          if(isNumber(chara)==true){
               if(even(chara)==true)
                    valid=false;
          if((upperVowel(chara)==true)||(lowerVowel(chara)==true))
               valid=false;
          return valid;
}So in my test class i'd have something like this:
public class test {
public static void main(String[] args){
     NoVowelNoEven test1 = new NoVowelNoEven();
     NoVowelNoEven test2 = new NoVowelNoEven("hello 123");
     System.out.println(test1.getOriginal());
     //This prints hello   (default constructor string is "hello")
     System.out.println(test1.countValidChar(test1.getOriginal()));
     //This prints 3
     System.out.println(test1.getValidString());
     //This SHOULD print hll
}

Remove $%&* characters from a String

Hi,
I have the following program that is supposed to detect a subsequence from a String (that contains $ signs) and remove it. This is a bit tricky, since because of $ signs, the replaceAll method for String does not work. When I use replaceAll for removing the part of the String w/ no $ signs, replaceAll works perfectly, but my code needs to cover the $ signs as well.
So far, except for replaceAll, I have tried the following, with the intent to first remove $ signs from only that specific sequence in the String (in this case from $d $e $f) and then remove the remaining, which is d e f.
If anyone has any idea on this, I would greatly appreciate it!
Looking forward to your help!
public class StringDivider {
     public static void main(String [] args)
          String symbols = "$a $b $c $d $e $f $g $h $i $j $k l m n o p";
         String removeSymbols = "$d $e $f";
         int startIndex = symbols.indexOf(removeSymbols);
         int endIndex = startIndex + removeSymbols.length()-1;
         for(int i=startIndex;i<endIndex+1;i++)
              if(symbols.charAt(i)=='$')
                   //not sure what to do here, I tried using replace(oldChar, newChar), but I couldn't achieve my point, which is to
                   //delete $ signs from the specific sequence only (as opposed to all the $ signs)
         System.out.println(symbols);
}

A little modification on the last version:
This one's more accurate.
public class StringDivider {
     public static void main(String [] args){
          String symbols = "$a $b $c $d $e $f $g $h $i $j $k l m n o p";
              String removeSymbols = "$d $e $f $g";
              if(symbols.indexOf(removeSymbols)!=-1)
                   if(removeSymbols.indexOf("$")!=-1)
                        removeSymbols = removeSymbols.replace('$', ' ').trim();
                        removeSymbols = removeSymbols.replaceAll("[ ]+", " ");
                        String [] symbolsWithoutSpecialChars = removeSymbols.split(" ");
                        for(int i=0;i<symbolsWithoutSpecialChars.length;i++)
                             symbols = symbols.replaceAll("[\\$]*"+symbolsWithoutSpecialChars, "");
                         symbols = symbols.replaceAll("[ ]+", " ");
               else
                    symbols = symbols.replaceAll(removeSymbols, "");
          symbols = symbols.trim();
          System.out.println(symbols);

Removing characters from a String

Hi!
I have a large String that has some unwanted characters in it that I want to remove. Here is an example:
AA1lbmNvZGVkUGFy\015\012YW1zdAACW0JbABBlbm5MQ2Is there any method I can use to remove the characters \015\012 from the String. I looked at the method String.replace(char, char); but this is unsuitable because I can only remove one charater at a time an I may have this character occuring legitimately elsewhere in my String. Would it be possible in some way to traverse the String and identify the pattern of \015\012 and remove that.
I'd appreciate any help,
Thanks
Chris

Specifically, str = str.replaceAll("\\\\01[25]", "");The replaceAll method is only available in v1.4.0 or later.

Removing characters

I need some help on removing characters from a string. The problem I am having is due to the fact the portion of the string I need to keep varies. A few examples are:
1298-1011-1-842-10-0
1298-1011-1-842-103-0
1298-1011-1-842-1034-0
1298-1011-1-842-10345-0
I need only the fifth set of numbers (10,103,1034,10345) out of these id numbers. I guess I need a way to remove everything with a "-" from both the right and left of the fifth set of numbers. The left function works to remove the trailing two digits ("-0") off of each string. I am just having a problem figuring out how to strip out the rest when it varies. Any help would be appreciated.

If you are using 10g you could use REGEXP_REPLACE. For example...
create table test1 (col1 varchar2(50));
insert into test1 values ('1298-1011-1-842-10-0');
insert into test1 values ('1298-1011-1-842-103-0');
insert into test1 values ('1298-1011-1-842-1034-0');
insert into test1 values ('1298-1011-1-842-10345-0');
create table test2 (c1 number, c2 varchar2(10));
insert into test2 values (10, 'a');
insert into test2 values (103, 'b');
insert into test2 values (1034, 'c');
insert into test2 values (10345, 'd');
SQL> select regexp_replace(col1, '.*-.*-.*-.*-(.*)-.*', '\1') col5 from test1;
COL5
10
103
1034
10345
SQL> select t1.*, t2.* from test1 t1, test2 t2
2 where regexp_replace(t1.col1, '.*-.*-.*-.*-(.*)-.*', '\1') = t2.c1;

1298-1011-1-842-10-0                                       10 a
1298-1011-1-842-103-0                                     103 b
1298-1011-1-842-1034-0                                   1034 c

Unable to read more than 255 characters in a string data type.

Hello,
I am using Crystal Reports version 11.5.8.826 to generate reports from databases such as MS-Excel & BaaN.
In Excel, there are records which carry string lengths of more than 255 characters. All though the fields are getting displayed in the report, the data being displayed gets truncated once it reaches a length of 255 characters.
Kindly provide me with a solution this problem.
Regards

Hello Manish,
I know that older versions of Crystal (Crystal 10 and older ) had a limitation of only 256 Characters for a string value. You should be able to use this code to get what you need.
We were successfully able to print out the Declaration of Independence through a Crystal report using something very similiar to this.

Removing non english characters from my string input source

Guys,
I have problem where I need to remove all non english (Latin) characters from a string, what should be the right API to do this?
One I'm using right now is:
s.replaceAll("[^\\x00-\\x7F]", "");//s is a string having chinese characters.
I'm looking for a standard Solution for such problems, where we deal with multiple lingual characters.
TIA
Nitin

I have a string which has Chinese as well as Japanese characters, and I only want to remove only Chinese characters.
What's the best way to go about it?Oh, I see!
Well, the problem here is that Strings don't have any information on the language. What you can get out of a String (provided you have the necessary data from the Unicode standard) is the script that is used.
A script can be used for multiple languages (for example English and German use mostly the same script, even if there are a few characters that are only used in German).
A language can use multiple scripts (for example Japanese uses Kanji, Hiragana and Katakana).
And if I remember correctly, then Japanese and Chinese texts share some characters on the Unicode plane (I might be wrong, 'though, since I speak/write neither of those languages).
These two facts make these kinds of detections hard to do. In some cases they are easy (separating latin-script texts from anything else) in others it may be much tougher or even impossible (Chinese/Japanese).

Removing non-alpha-numeric characters from a string

How can I remove all non-alpha-numeric characters from a string? (i.e. only alpha-numerics should remain in the string).

Or even without a loop ?
Extract from the help for the Search and Replace String function :
Right-click the Search and Replace String function and select Regular Expression from the shortcut menu to configure the function for advanced regular expression searches and partial match substitution in the replacement string.
Extract from the for the advanced search options :
[a-zA-Z0-9] matches any lowercase or uppercase letter or any digit. You also can use a character class to match any character not in a given set by adding a caret (^) to the beginning of the class. For example [^a-zA-Z0-9] matches any character that is not a lowercase or uppercase letter and also not a digit.

Removing characters from string after a certain point

Im very new to java programming, so if this is a realy stupid question, please forgive me
I want to remove all the characters in my string that are after a certain character, such as a backslash. eg: if i have string called "myString" and it contains this:
109072\We Are The Champions\GEMINI
205305\We Are The Champions\Queen
4416\We Are The Champions\A Knight's Tale
a00022723\We Are The Champions\GREEN DAYi would like to remove all the characters after the first slash (109072*\*We...) leaving the string as "109072"
the main problem is that the number of characters before and after is not the always the same, and there is often letters in the string i want, so it cant be separated by removing all letters and leaving the numbers
Is there any way that this can be done?
Thanks in advance for all help.

You must learn to use the Javadoc for the standard classes. You can download it or reference it on line. For example [http://java.sun.com/javase/6/docs/api/java/lang/String.html|http://java.sun.com/javase/6/docs/api/java/lang/String.html].

Removing unwanted characters from imported string

Hello,
I have a tab-delimited .txt file which I have to import into Indesign for further processing.
The file is composed by a 3 columns header row at the beginning (Code, Description, price) followed by a series of 3 columns data rows.
The problem is that sometimes, depending on the way the txt/csv file has been created, may include unwanted characters (such as spaces, double spaces, etc.).
Is there a way to "clean" the imported strings from these unwanted characters?
This is my starting code:
function processImportedTxt(){
    //Open .csv file
    var csvFile = File.openDialog("Open file .csv","tab-delimited(*.csv):*.csv;");
    datafile = new File(csvFile);
    if (datafile.exists){
        datafile.open('r');
   var csvData = new Array();
   while(!datafile.eof){//read every row till the end of file
        csvData.push(datafile.readln());
    datafile.close();
    for(a=1; a<csvData.length; a++){
        var myRowData = csvData[a];//row of data
        var mySplitData = myRowData.toString().split("\t");//divide columns
        var myRowCode = mySplitData[0];
        var myRowDesc = mySplitData[1];
        var myRowPrice = mySplitData[2];
        // Here goes code for cleaning strings from unwanted characters
processImportedTxt();
Any help would be much appreciated
Thanks in advance

Hi,
If you want to safe 1-space occurences just a small correction:
i.e.:
var myRowCode = mySplitData[0].replace(/\s\s+/g,'');

RegExp for excluding special characters in a string.

Hi All,
Im using Flex RegExpValidator. Can anyone suggest me the correct expression to validate this condition?....
I have tried this expression :----- /^[^///\/</>/?/*&]+$/...But in this it is also negating the alphabets.Also I have tried with opposite condition that in the String we should have alphabets and the expression is:-- ([a-z]|[A-Z]|[0-9]|[ ]|[-]|[_])*..... Please can anyone help me on this.

I want to take a series of hex characters in a string control and produce an HDLC string indicator for example if the data string control is 3F27 then the HDLC string indicator is 7E003F2700B57E

"thanks for your help "
Does that mean you figured it out already?
If not, see this thread for some HDLC related code.

Xml string in Java - forbidden characters for data?

Hi there,
In my java class I am building a xml string and saving it as a xml file in the hard drive. Later when I open the file in the XML editor it gets errors "forbidden characters". I think the problem is that in the data there can be characters as & or <> and of course that would disturbe the xml structure. Is there any smart method in Java which convert all the forbidden characters for xml data?... many thanks for any hints.

And it isn't.
So the real solution is to build it correctly in the first place.
Is there any smart method in Java which convert all the forbidden characters for xml data?There are also libraries that will allow you to build xml which handle those sorts of issues for you.

Removing Duplicate Characters in a String without using a Hashset

I was wondering if anyone knew a way of removing duplicate characters in a string without using a Hashset.
I want to go from
helloworld -> helowrd

okay, here it is
1) use a loop, look through each character in the original string
2) look at the new string, if this character exist, don't add it, otherwise add it.
check out methods in java.lang.String
