I'm really having trouble with displaying whether the first string is a substring of the other and was wondering if someone can help me out.

Thanks

Also, you have to ignore the case. I don't know how to do that because the "contains" method doesn't have ignore case.

Be sure to familiarize yourself with all the methods that we went over in class.  You should be writing test programs which use these methods so you know how they work and that should give you an idea of how to apply them to the homework problems.  Also, even if there isn't a direct "ignores case" version of a method, doesn't mean there isn't a way to accomplish what you want.  You might have to do a few extra steps to get there.
