I use a regexps for such tasks. In your case it should look something like this:

String str = "today is tuesday";
return str.matches(".*?\\bt\\b.*?"); // returns "false"

String str = "today is t uesday";
return str.matches(".*?\\bt\\b.*?"); // returns "true"

A short explanation:

. matches any character, *? is for zero or more times, \b is a word boundary.

More information on regexps can be found here or specifically for java here
