抽象类调用自己的抽象方法，实现来自实现类（很常用）_chinoukin的博客_抽象类调用抽象方法

直接上代码

public abstract class Parent {

    public abstract void dosomething();

    public void say(){
        dosomething();
        System.out.println("www.chinoukin.com");
    }
}

public class Children extends Parent{
    @Override
    public void dosomething() {
        System.out.println("张三来啦");
    }

    public static void main(String[] args){
        Children c = new Children();
        c.say();
    }
}public abstract class Parent {
