Java HashMap return value not confirming with my understanding of equals and hashcode

Question

The output of the following code sample is:

{1--e=e2, 2--e1=e1}

package com.sid.practice;

import java.util.HashMap;
import         


        

Answer 1

Actually, you got it backwards. The value was overridden. The key wasn't replaced since as far as HashMap is concerned, e and e2 are identical.

Your output is {1--e=e2, 2--e1=e1}:

key = e, value = "e2" (which overrode the old value "e")
key = e1, value = "e1"
