Question

java.lang.

Answer 1

You can't place code outside methods in Java. You have

System.out.println("Enter the value of r");

which is not belonging to anything. Fix these issues and the problem will go away.

Just for curiosity, how should code outside methods be called and from what according to you? What I mean is that the execution is made by a code flow which starts from a entry point (the main method in Java) and jumps to methods called, eventually spawning other threads. Code which doesn't reside inside a method is not reachable nor it leads to anything.
