I have two strings, like so:

String str1 = "He is doing very good";
String str2 = "doing";

I want to know how to find the word "doing" in string str1, even if str1 is changed like so:

str1 = "He isdoing very good";

Check the docs before asking a question. This is as basic as it gets. — keyser, Sep 29 '12 at 11:43

The easiest way would be

str1.contains(str2);

How about the String.contains method?
