Hanz Fenster Make use of the basic for loop in your program because it will suit your code more. The for-each loop in Java is basically used for traversing the elements in an array or a collection. You cannot use it to assign values to the array that you have declared. Also there are a lot of errors and I recommend you to revise the course or topics again to understand what you actually trying to do.

First: You miss the Scanner input declaration Scanner input = new Scanner(System.in); Edit: Second What Avinesh said.

Why b>5 and c>5 ? It should be b<5 and c<5.

I think you should rename your variable. What does a, b, c, d mean?
