this是当前类的引用吧
super是指调用父类的构造函数
如:
public class Student extends SuperStudent{
private int id;
private String name;
//省略setget方法
public Student(int id){
this.id = id;
}
public Sthdent(int id,String name){
this(1);// 此处调用的是当前的相对应的构架函数
this.name = name;
super(id,name,"男");// 此处就是调用父类SuperStudent中的构造函数
}
}
SuperStudent类
public class SuperStudent{
private int id;
private String name;
private String sex;
// 省略 set get
public SuperStudent(int id,String name,String sex){
this.id = id;
this.name = name;
this.sex = sex;
}
