Answer 1

You must escape the quotes " inside Strings by writing \". If you don't do this, the Strings will end too early.

Edit: Example:

String thisWillNotCompile =  "This String terminates right now" and not later";

Trying to compile this will give you a syntax error.

String thisWillCompile = "This String doesn't terminate right now\" but now";

This works.

Edit 2: For more details read up on Escape Sequences in the Java Tutorial.
