Static method ... gives an error

Question

Program-1
This is OK.
Will give expected the output - Hello
public class test{
public static void main(String argv[]){
            test t = new test();
     t.Hello();
      public void Hello(){
     System.out.println("Hello");
Program-2
This is also OK.
Will give expected output - Hello
public class test{
public static void main(String argv[]){
        Hello();
      public static void Hello(){
     System.out.println("Hello");
Program-A
import java.awt.*;
import java.awt.event.*;
public class test extends Frame {
public static void main(String argv[]){
        test mwc = new test();
     mwc.MyWc();
      public void  MyWc(){
        setSize(300,300);
        setVisible(true);
}This program is much similar to the above Program-1
This is also give the expected output.
BUT...
this is also similar to the above Program-2
This gives compilation error
WHY IS THAT ???
Program-B
import java.awt.*;
import java.awt.event.*;
public class test extends Frame {
public static void main(String argv[]){
        MyWc();
      public static void  MyWc(){
        setSize(300,300);
        setVisible(true);
Simply,
Program-1 and Program-A are logically similar. And they behave as expected.
(Creating the object and calling the method)
Also
Program-2 and Program-B are logically similar.(Seems to be)
(Call the method without creating the object.used static)
But why Program-B gives an error ???

Answer 1

Remember that static methods do not belong to a particular instance of a class. Therefore what are setting the size of and what are you making visible?
