Have you thought about how you would do it "by hand"? If not, you need to.

Have you looked at String's javadocs for methods that might help you with the various steps of your "by hand" process (once you get that figured out in detail)? If not, you need to.

In general, you'll need to ShowSomeEffort(⇐click) and TellTheDetails(⇐click) about what exactly you tried and what specific trouble you're having.

I Believe you want the toUpperCase method

String string=//whatever your string is?
string=string.toUpperCase();
return string;

I think this is what you want but you didn't give much detail

You do realise you cannot change the contents of a String? You can only replace it with a different String. You are better off using a StringBuilder[←link], which is designed for rapid changes
