Line 22 is an invalid constructor declaration line -- for multiple reasons. Please refer to this page of the java tutorials.

This message, 'invalid method declaration return type required', is trying to tell you that you need to include type declarations to the elements within the round brackets. When the compiler reads this line (line 22 above), it recognizes that you are declaring a method or constructor. It will then need to know certain things about it so it can direct the calling statement(s) to it. Mainly, it needs to know the name of the code-block and the order and type of the arguments passed to it. I have never seen literal values as arguments -- only have I seen variable names (with their types -- for examples; 'int howMany', 'String title', 'Actor actor').
