Ok, I have heard from many places and sources that whenever I override the equals() method, I need to override the hashCode() method as well. But consider the following piece of code

package test;

public class MyCustomObject {

    int intVal1;
    int intVal2;

    public MyCustomObject(int val1, int val2){
        intVal1 = val1;
        intVal2 = val2;
    }

    public boolean equals(Object obj){
        return (((MyCustomObject)obj).intVal1 == this.intVal1) && 
                (((MyCustomObject)obj).intVal2 == this.intVal2);
    }

    public static void main(String a[]){
        MyCustomObject m1 = new MyCustomObject(3,5);
        MyCustomObject m2 = new MyCustomObject(3,5);
        MyCustomObject m3 = new MyCustomObject(4,5);

        System.out.println(m1.equals(m2));
        System.out.println(m1.equals(m3));
    }
}

Here the output is true, false exactly the way I want it to be and I dont care of overriding the hashCode() method at all. This means that hashCode() overriding is an option rather being a mandatory one as everyone says.

I want a second confirmation.
