Three uses of this keyword in java

This is an object of its own, representing the object itself. It can be understood as: a pointer to the object itself.

The usage of this in Java can be roughly divided into three types:

1. Ordinary direct reference, this is equivalent to pointing to the current object itself.

(Recommended tutorial: java introductory tutorial)

2. The names of participating members have the same name, use this to distinguish them:

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

3. Quote The constructor of this class

class Person{
    private String name;
    private int age;
    
    public Person() {
    }
 
    public Person(String name) {
        this.name = name;
    }
    public Person(String name, int age) {
        this(name);
        this.age = age;
    }
}
