JAVA#方法重载'学习札记

1.DEFs of OVERLOAD:声明在同一个类中,方法名相同但方法的参数列表不同的方法构成方法重载。

其中,参数列表不同分为1️⃣参数的个数不同2️⃣参数类型不同

2.e.g.

public class Overload {
    public static void main(String[] args) {
        Overload o=new Overload();
        o.AllenIverso("a");
        o.AllenIverson();
        o.AllenIverson(23);
        o.AllenIverson(23,24)
    }
    //如下四个方法构成方法重载
    public void AllenIverson(){
        System.out.println("小艾可是96年黄金一代的状元啊");
    }
    public void AllenIverson(int sxai){
        System.out.println("I am what I am");

    }
    public void AllenIverson(int sxai,int kobe){
        System.out.println("Only the strong survive");
    }
    public void AllenIverso(String sxai){
        System.out.println("Allen Iverson was the Best Bball player amid the Michael Jordan Dynasty");

    }

}

编译运行:

Allen Iverson was the Best Bball player amid the Michael Jordan Dynasty
小艾可是96年黄金一代的状元啊
I am what I am
Only the strong survive
