I think the main() doesn't have args. It is a problem.
But I get the runtime error. I think it should be compiling
Btw, main is the keyword?
what is the definition of keyword.
public class TestClass
public static void main(){ new TestClass().sayHello(); } //1
public static void sayHello(){ System.out.println("Static Hello World"); } //2
public void sayHello() { System.out.println("Hello World "); } //3

No, it will be a runtime error. When the compiler comes accross your main definition, it just considers it another method. Now when you try to execute your program, the JVM cannot find a properly defined main method, then it barks!
