Question2

1.  package com.dan.chisholm;
2. public class A {
3.    public void m1() {
4.       System.out.println("A.m1, "); }
5.    protected void m2() {
6.       System.out.println("A.m2, "); }
7.    private void m3() {
8.       System.out.println("A.m3, "); }
9.     void m4(){
10.        System.out.println("A.m4, "); }
11. }
12. 
    
13. class B {
14.     public static void main(String args[]){
15.           A a = new A();
16.           a.m1(); 
17.           a.m2();
18.           a.m3();
19.           a.m4();
20.    }
21. }
