What do you think?
This sounds rather like homework.

You didn't bother to reply to PhHein's response in your first thread, and I see no reason to expect better behavior here.

What is advanced about this question? It is Java 101

"==" and equals() both compare if the objects reference variables refer to the same instance of an object.
But the equals() method can be over-ridden. For example, an employee class may have an equals method which makes two employee reference variables equal if
their employeeId's are equal. Consider
Employee emp1 = new Employee();
Employee emp2 = new Employee();
emp1.equals(emp2) is true if the employeeId's are equal but emp1==emp2 is not true. So when ever u need to specify a custom condition for equality u can over ride equals() and use it. Do remember that u have to over ride hashcode() when ever equals() is over ridden.

Most (if not all) of us know the answer to your (elementary) question and you're not the one to decide who is allowed to post a reply or not.
