You can use substring function   s substring 0 s length   - 2      With the first 0  you say to substring that it has to start in the first character of your string and with the s length   - 2  that it has to finish 2 characters before the String ends   For more information about substring function you can see here   http   docs oracle com javase 7 docs api java lang String html

You may use the following method to remove last n character -    public String removeLast String s  int n        if  null    s  amp  amp   s isEmpty              s   s substring 0  s length  -n             return s

Use String substring beginIndex  endIndex   str substring 0  str length   - 2     The substring begins at the specified beginIndex and extends to the character at index  endIndex - 1

An alternative solution would be to use some sort of regex   for example       String s    apple car 04 48 05 18 05 46 06 16 06 46 07 16 07 46 16 46 17 16 17 46 18 16 18 46 19 16       String results   s replaceAll   0-9        replaceAll              first removing all the numbers then remove space followed by       System out println results      output 9     System out println results length       output  apple car

It was almost correct just change your  last line like    String stopEnd   stop substring 0  stop length   - 1     replace stopName with stop    OR    you can replace your last two lines   String stopEnd     stopName substring 0  stopName length   - 2

Subtract -2 or -3 basis of removing last space also    public static void main String   args            String s    apple car 05           System out println s substring 0  s length   - 2            Output  apple car

You may also try the following code with exception handling  Here you have a method removeLast String s  int n   it is actually an modified version of masud m s answer   You have to provide the String s and how many char  you want to remove from the last to this removeLast String s  int n  function  If the number of chars have to remove from the last is greater than the given String length then it throws a StringIndexOutOfBoundException with a custom message -    public String removeLast String s  int n  throws StringIndexOutOfBoundsException           int strLength   s length             if n gt strLength               throw new StringIndexOutOfBoundsException  Number of character to remove from end is greater than the length of the string                       else if null  s  amp  amp   s isEmpty                  s   s substring 0  s length  -n                      return s
