Return selected number of characters from a string

How do you select a certain number of charaters from a string?
For example:
I have a string that contains 51-108
I want to separate the string into two strings one containing 51 and another one containing 108.

A StringTokenizer will do it.
StringTokenizer strtok = new StringTokenizer(yourString, "-");

  • 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
    }

  • Reading in a certain number of characters from a file.

    Hi guys,
    I need some pointers on how to read in a specified number of characters from a text file.For example,how would I read in the first 100 characters to an array from a text file with an unspecfied number of characters (more than 100 rather than less!).
    At present I am getting code errors being thrown due to reading in beyond the array size ie
    java.lang.ArrayIndexOutOfBoundsException: 100.

    post more code , this exception tells me nothing
    without seeing what you are actually doing.
    public String getText (String file)//textfile to be analyzed will be inputted as argument 150407 0356
       //15042007 0612 Check notes on overloaded getText method below.
           int temp;
           inputFile = file;
           int i=0;
                try
                    BufferedReader bGetFile = new BufferedReader (new FileReader(inputFile));
                    while ((temp=bGetFile.read())!=-1)
                        textFromFile[i] = (char)temp;

                catch (IOException e)
                    System.out.println (" ");
                    System.out.println ("Sorry.An error occurred while trying to read from the input file.Unable to proceed!");
                System.out.println ("Processing the input text file "); //25042007 2318 being used for debugging purposes.          
                return inputText;
        }If the file being read is greater than MAX characters it will throw the exception mentioned.What I would like to do is read in MAX characters and discard the rest.

  • Coding - returning the number of characters in a text box.

    I am in the process of creating a cell phone simulation/animation in Edge Animate CC for use in a Captivate course. Basically, when a user clicks on number buttons on the virtual keypad, it displays the numbers in a text box , just like an actual cell phone would display the phone number on the screen as a caller is dialing. So, the user would click seven buttons and a seven-digit phone number appears on the virtual phone screen.  This part of my animation works great and all seven digits appear, but I would like to modify the code so that a hyphen appears after the third button clicked. This way, the output better resembles an actual phone number instead of just a string of seven digits.
    Here is an example of the code I currently have assigned to the #2 button on the virtual keypad:
    var text = sym.$("PhoneNum").html();
    text = text + 2;
    sym.$("PhoneNum").html(text);
    PhoneNum is the name of my text box on the stage where the digits appear as each keypad button is clicked.
    In order to incorporate the hyphen after the third button clicked, I need to somehow return the current number of characters in the PhoneNum text box, then create an if/else scenario that applies the hyphen after the third button clicked.
    Does anyone know how I can use either JavaScript or jQuery to return the number of characters currently in the PhoneNum text box?

    No problem!
    Basically the thing to remember is that unless you are needing to pass html to the object, you can use text() instead. text() also gives you the raw text without any html formatting (so you can assume what .html() would return)

  • 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.

  • Method to count number of characters in a string?

    hi.
    i'm trying to write some script that will count the number of characters in a string passed into a constructor and then compare it against another value to check whether the string passed in is valid.
    something like this
    public class Stringcheck
    public static int maxStringLength;
    public static double minSize;
    public static boolean testStringLength(String x)
    // Insert method for counting number of chars in String x and name as 'int numberOfChars
    if(number of Chars <= maxStringLength )
    return true;
    else
    return false;
    can someone help me with writing this script.
    Thanks
    Richard.

    ummm, you dont need anything fancy. try:
    String test = "this is the test string";
    int length = test.length();

  • 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

    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).

    Hi,
    you can make use of string operation FIND as:

  • 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

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