Now from here confusion starts some time interviewer will say that since Hashcode is equal objects are equal and HashMap will throw exception or not store it again etc. then you might want to remind them aobut equals and hashCode() contract that two unequal object in Java very much can have...

This hashcode is used to calculate index for above Entry[] table. Now, If you see at array index 10 in above diagram, It has an Entry object named HashMap$Entry . We have put 4 key-values in Hashmap but it seems to have only 2!!! This is because if two objects have same hashco...

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer. Given that the JVM will relocate objects (e.g. during garbage collection cycles due to promotion or compaction), after we calculat...
