For theMapwith user-defined objects as values, we need to customize the equality method using one of the methods mentioned in thecomparingHashMaps article. Otherwise, the checks will fail: //Comparing a Map<Integer, Map<String, String>> and Map<Integer, Map<Integer, Address>> map assertNot...

factory methods provided (i.e., createBucket ) for TestHashMapBuckets.java to pass. If you choose to implement the additional remove , keySet , and iterator methods, we provide some tests in TestHashMapExtra.java . If the resulting value after the % operation is negative, you can add the...
The right answer in the first place is presumably that any Serializable object which contains a Set (or other abstract type not documented as Serializable) must implement its own readObject and writeObject methods which (de-)serialize the set manually. Either that, or define the object to ...
All data structures implement the container interface with the following methods: type Container interface { Empty() bool Size() int Clear() Values() []interface{} } Containers are either ordered or unordered. All ordered containers provide stateful iterators and some of them allow enumerable funct...
