zd.shark.类的标识与访问控制

源码如下（基于JAVA编程百例）

 

package shark.zd.类的标识和访问控制.com;

public class classDemo {
    public void method1() {
    System.out.println("1:public");
}
    private void method2() {
        System.out.println("2:private");
    }
    protected void method3() {
        System.out.println("3:protected");
    }
    public static void main(String[] arges){
        classDemo ov = new classDemo();
        ov.method1();
        ov.method2();
        ov.method3();
        
        
    }
}
package shark.zd.类的标识和访问控制.com;

public class classplay {
    public static void main(String[] arges){
        classDemo ov = new classDemo();
        ov.method1();
        ov.method3();
    }
}
package shark.zd.类的标识和访问控制.net;

import shark.zd.类的标识和访问控制.com.classDemo;

public class classplay {
    public static void main(String[] arges){
        classDemo ov = new classDemo();
        ov.method1();
    
        
    }
}
