Java继承构造器

 

 

 兄弟构造器应用：

package com.superwy.extendsdemo2;

public class Test {
    public static void main(String[] args) {
        Stuedent s1 = new Stuedent("superwy",24);
        System.out.println(s1.getName() + s1.getAge() + s1.getSchoolName());
        Stuedent s2 = new Stuedent("Stephen",36,"golden");
        System.out.println(s2.getName() + s2.getAge() + s2.getSchoolName() );
    }
}

class Stuedent{
    private String name;
    private int age;
    private String schoolName;

    public Stuedent() {

    }
    //默认学校赋值
    public Stuedent(String name, int age) {
        this(name, age,"uestc");
    }

    public Stuedent(String name, int age, String schoolName) {
        this.name = name;
        this.age = age;
        this.schoolName = schoolName;
    }

    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;
    }

    public String getSchoolName() {
        return schoolName;
    }

    public void setSchoolName(String schoolName) {
        this.schoolName = schoolName;
    }
}
