You're calling PrintStream's println() method and passing in the return value of the return_Number() method. However, the return type of the return_Number() method is void, which is why it's not valid to pass the result of this method as an argument to the println() method - the return_Number() method doesn't yield a return value.

The return type of both the methods that are called in the println statement are void, So it doesnot return anything and thus the error.
 
It is sorta covered in the JavaRanch Style Guide.
