JAVA编程制作的几个程序

package com.javabook.ch03;

public class AccessControl {

	/**
	 * @param args
	 */
	
	public int a;
	private int b;
	protected int c;
	int d;
	
	public void f1(){
		System.out.println("公有方法");
	}
	
	private void f2(){
		System.out.println("私有方法");
	}
	protected void f3(){
		System.out.println("保护方法");
	}
	 void f4(){
		System.out.println("友好方法");
	}
		
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub

		AccessControl test = new AccessControl();
		
		test.a=1;
		System.out.print("公有属性a="+test.a);
		test.b=2;
		System.out.print("私有属性b="+test.b);
		test.c=3;
		System.out.print("保护属性c="+test.c);
		test.d=1;
		System.out.print("友好属性d="+test.d);
