Using Java8 to code game.

Develop an app based on the code below that adds the following features:

• Players take it in turns to place 3 units at a time on a territory that they control and then one unit for each neutral. The user types in the name of the territories. The user should be allowed to enter a shortened version of the name, so long as it is unambiguous. After each selection, update the map.

• The user should receive appropriate error messages if their commands are invalid.
