How can I remove the empty string resulting from a split?

When I split a String :

A.B.C.

by .. I get 4 strings. The fourth being the white space. How can I remove that ?

String tokens[] = text.split("\\.");
    for(String token : tokens) {
        System.out.println("Token : " + token);
    }

If whitespace at the beginning or end is the problem, trim it off:

String tokens[] = text.trim().split("\\.");

Your String is A.B.C. so that whenever you split that it with . it will be give four substrings only. Even though you use trim() it will give four substrings. So try to remove last . and then split string. You will get proper output.

Remove all the whitespace with a replaceAll() before your code.

text.replaceAll("\\s+","");
