Remove a particular token from a string

I have to remove a particular token from a String variable.

for eg: If the String variable is like "GUID+456709876790" I need to remove the "GUID+" part from the string and only need "456709876790".

How can it be done?

this works for me

String Line="test line 1234 abdc",aux;
token=new StringTokenizer(Line);

 while(token.hasMoreTokens())
   if(!("1234").equals(aux=token.nextToken())){ 
     new_line+= aux+" ";
     System.out.println("la nueva string es: "+ new_line);
   }

If you're using apache.commons.lang library you can use StringUtils just do:

StringUtils.remove(yourString, token);

Just try this one :

String a = "GUID+456709876790";
String s = a.replaceAll("\\D","");

I am assuming that you want only digits as I have used regex here to remove any thing that is not a digit

  String str = "GUID+456709876790"

 str.substring(str.indexOf("+")+1)

String s = "GUID+456709876790";
String token = "GUID+";
s = s.substring(s.indexOf(token) + token.length());
// or s = s.replace(token, "");

Two options:

  • As you're just removing from the start, you can really easily use substring:

    text = text.substring(5);
// Or possibly more clearly...
text = text.substring("GUID+".length());

  • To remove it everywhere in the string, just use replace:

    text = text.replace("GUID+", "");

Note the use of String.replace() in the latter case, rather than String.replaceAll() - the latter uses regular expressions, which would affect the meaning of +.
