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<Int

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...

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 ...
