What does this.object.method(this) do?

Question

For example object1 has an instance method1:

public void method1() {
    this.object2.method2(this);
}

Would the first 'this' refer to the object 1 and the second 'this' object 2 ?

No, `this` in this case both means `object1`, from this code you can tell the there is a field in this class that is called `object2` — Scary Wombat, Jun 13 '19 at 01:54

In your code the this keyword give the method a sense of which variable, object or instance it will call, while this can also call the parents variable, object, instance or method. So when it calls this.object2.method2(this) it actually calling for the object2's method2 with a parameter of the class. In your scope there is a code that instantiate the object2 and it is declared outside any method of the class. See more in here: use of this (javadocs)
