    Hello everyone,

    I'm in a middle of confusion now. I'm trying to use the String java class to replace all occurences of word in sub to word in put. The problem is, this doesn't work:

    String sub = "Hello";
    String put = "Hi";

    line.replaceAll(sub, put);

    I've been searching through google and other stuff, but I still couldn't understand what went wrong, please help!

    replaceAll returns a new string with the results of the replacement.
