What is the meaning of “this” in Java?

Question

Normally, I use this in constructors only.

I understand that it is used to identify the parameter variable (by using this.something), if i

Answer 1

As everyone said, this represents the current object / current instance. I understand it this way, if its just "this" - it returns class object, in below ex: Dog if it has this.something, something is a method in that class or a variable

class Dog {
private String breed;
private String name;

Dog(String breed, String name) {
    this.breed = breed;
    this.name = name;
}

public Dog getDog() {
    // return Dog type
    return this;
}

}
