HashCode is a value computed in such way to be unique as possible to improve performance while retrieving object in HashedCollections. If for example you have a HashMap, and didn't overrride hashCode() method all your objects will be in the same bucket resulting a slow execution while retrieving an object. But if you do provide an efficient implementation of hashCode() method your objects will be stored across many buckets and you look up for one of them, the api does calculate the hashCode of your object and then it selects the right bucket. After that we go through the bucket to find the needed object.
