The Object class

In this section, we're going to learn some very important things about how Java has chosen to implement object-oriented programming. We're going to be exploring the Object class itself. To get us started, I've written a really basic program:

package theobjectclass; 
 
public class TheObjectClass { 
     
    public static void main(String[] args) { 
        MyClass object1 = new MyClass("abcdefg"); 
        MyClass object2 = new MyClass("abcdefg"); 
         
        object1.MyMethod(); 
        object2.MyMethod(); 
         
        System.out.println("The objects are the same: " +         (object1 == object2)); 
        System.out.println("The objects are the same: " +         object1.equals(object2)); 
    } 
 
} 

This program utilizes a custom class called MyClass and creates two instances of this class: object1 and object2
