substring to get a space j2ME

I have a string that end with a space like this :

String s="somthing= "

I want to get that space so I do :

s.substring(s.indexOf("=")+1).trim()

but it doesn't work. Any idea?

You're not modifying your string s, just the substring. The specs say that substring()

Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex.

The trim() method affects the substring, not s, so that's why it doesn't work. By doing s.trim() directly you'll remove the whitespaces at the end (and beginning) of s, but watch out since this method also returns a new ("a copy" says the specs) String, so try doing s = s.trim();.
