Why do we have to override the equals() method in Java?

Question

I have some confusion about the reason that we override the .equals method.

For example:

Test test1 = new Test(3);
Test test2 = new Test         


        

Answer 1

By default .equals() uses == identity function to compare which obviously doesn't work as the instances test1 and test2 are not the same. == only works with primitive data types like int or string. So you need to override it to make it work by comparing all the member variables of the Test class
