Yes. Because you have no main method - you need to put any code (other than variable declarations) inside methods. The main method is the method that runs when you first start your program, *edit*


Oops, nevermind - I see that you do have a main method. For statements like String lang, then lang = "abc", you would need to initially just say String lang = "abc"; . . and what I said about only having variable declarations still stands. lang = "abc" is an assignment statement, and thus, isn't allowed unless you do it inside of a method.

Satisfied or not, he's right. Everything except variable declarations have to be inside a method. Post your latest code, with code=java tags.

Everything except variable declarations still have to be inside a method. Indent your code so you can see where methods and classes end. Your errors start immediately after the end of the init method because the following code isn't in a method.
This would have been obvious to you with proper indentation and code tags.

ps: If you have code that looks like this:
Java Syntax (Toggle Plain Text) 
  1. catch(Exception ee) {}
then what you are saying is: "if my code goes wrong I do not want to know why or where it happened. Please just stop executing and give me no help at all".
Try replacing all those with
Java Syntax (Toggle Plain Text) 
  1. catch(Exception ee) {
  2.   ee.printStackTrace();
  3. }
so you know what's happening.
