I tried running the program, though it compiled fine, it threw an error at Runtime. But my question is that why did the compiler allow the program to compile successfully. Is "long" valid in main?? Sonir

the main method is just an other method. It's perfectly valid to declare the main method as you did but the problem arises when you try to run the application because the interpreter is lokking for a method called main and declared as follows: public static void main(String args) replace long with void and it should run fine
That is a valid method declaration. As far as the compiler is concerned, it is no different than writing public static long aMethod(String stringArray)
However, if you want the virtual machine to "run" an application, must pass it a class that has a main method with this *exact* signature: public static void main(String args) Otherwise, it won't run. But as you can see, it compiles just fine.
