JAVA学习(10) 继承(2) 继承中的方法的覆盖和重载

若函数和父类同名,参数相同则覆盖,否则为重载

public class Test11A{

    public void somoke()
    {
        System.out.println("chouyan");
    }

}

public class Test11B extends Test11A{

    public void somoke()//覆盖父类的somoke方法
    {
        System.out.println("bu chou yan");
    }
    public static void main(String[] args) {
        Test11B test  = new Test11B();
        test.somoke();
    }

}

重载:

public class Test11B extends Test11A{

    public void somoke(String  s)//参数不同,会重载父类的方法
    {
        System.out.println(s);
    }
    public static void main(String[] args) {
        Test11B test  = new Test11B();
        test.somoke();
         test.somoke("hello");
    }

}
