In this string, I need your help to remove all spaces only after foo only if exists.

Answer 1

You can do something like this:

String s="abcfoobarfoo def xyzfoobcd fooaaafoo bar";
String str=s.replaceAll("foo ","foo");
System.out.println(str);

Answer 2

   String str = "abcfoobarfoo def xyzfoobcd fooaaafoo bar"; 
   String oldStr = "foo ";
   String newStr = "";
   String resultStr;
   resultStr = str.replace(oldStr, newStr);
   System.out.println("resultStr:"+resultStr);
