求问下列一句的存在意义

[josephliver]

public class Person {
public static int lastId = 0;
private String name;
private String gender;
private String address;
private int idNumber;
public Person(String name, String gender, String add) {
super();
this.name = name;
this.gender = gender;
this.address = add;
lastId++;
this.idNumber = lastId;
}
求问这里的super()用什么用意

[认真的学生]

super调用父类的构造器，放在这是调用Object的构造器？应该是没有用

调用父类Object的无参构造函数，不写也默认调用了。又不传参数，没必要写出来。
