if you don’t define your own
hashCodemethod, the method from the parent Class of your object gets called. If you have no parent defined thehashCodemethod from the Object class gets called. According to the java api documentation the method returns an integer depending on the address of the object – but how exactly this is accomplished depends on the jvm and the operating system.In summary – if you don’t specify any hashCode methods it’s like putting Objects in the hashTable.
