Flyweight compositeFly1 = flyFactory.factory(compositeState);
Flyweight compositeFly2 = flyFactory.factory(compositeState);
compositeFly1.operation("Composite Call");
System.out.println("---------------------------------");
System.out.println("复合享元模式是否可以共享对象：" + (compositeFly1 == compositeFly2));
Character state = 'a';
Flyweight fly1 = flyFactory.factory(state);
Flyweight fly2 = flyFactory.factory(state);
System.out.println("单纯享元模式是否可以共享对象：" + (fly1 == fly2));
}
}
运行结果如下：
[html]
Intrinsic State = b
Extrinsic State = Composite Call
Intrinsic State = c
Extrinsic State = Composite Call
Intrinsic State = a
Extrinsic State = Composite Call
---------------------------------
复合享元模式是否可以共享对象：false
单纯享元模式是否可以共享对象：true
Intrinsic State = b
Extrinsic State = Composite Call
Intrinsic State = c
Extrinsic State = Composite Call
Intrinsic State = a
Extrinsic State = Composite Call
---------------------------------
复合享元模式是否可以共享对象：false
单纯享元模式是否可以共享对象：true
