this 与 super 用途

一、this用途：

一是引用隐式参数，二是调用该类其他的构造器。

二、super用途：

一是调用超类的方法，二是调用超类的构造器

三、用法举例

package com.test.xqh;public class Manage extends Employee {private String sex;public Manage(String name, int age, String sex) {super(name, age); // super用途2，调用超类的构造器this.setSex(sex);}public String getName() {return super.getName() + "HHHH"; // super用途1, 调用超类的方法}public void setSex(String sex) {this.sex = sex;}public String getSex() {return sex;}public void say() {System.out.println("***");}public static void main(String[] args) {Employee[] e = new Employee[2];e[0] = new Employee("张三", 22);e[1] = new Manage("李四", 22, "男");System.out.println(e[0].getName());System.out.println(e[1].getName());}}class Employee {private String name;private int age;public Employee(String name, int age) {this(); // this用途2,调用该类的构造器（此例为默认的构造器）this.name = name; // this用途1，引用隐式参数this.age = age; // this用途1，引用隐式参数}public Employee() {}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}}
