Java object

Question

What happened when we pass an object as an argument?

Answer 1

Lets say you have a class named “cls” with 2 int values: x and y...

public void printCoords(cls obj) {
System.out.println(obj.x);
System.out.println(obj.y);
}

This will output its x and y position. You will also find other reasons to pass an object as an argument, this is just a basic example.

Answer 2

It works just like passing any other data type as an argument. You can think of a class as a new data type that you created.
