If Amory is a class, create an instance of it using new and then you can call its methods:
Amory amry = new Amory();
int value = army.getValue(); // get value
For the above import to find the class Amory, the class file would be in a folder MyGame and the classpath would end at the folder containing MyGame. Amory would be in the package: MyGame.
If none of this makes sense, go read about packages, classpath and import statement.
