内部类调用问题

[littlely_ll]

interface Incrementable{
	void increment();
}
class Callee1 implements Incrementable{
	private int i = 0;
	public void increment(){
		i++;
		System.out.println(i);
	}
}
class MyIncrement{
	public void increment(){System.out.println("Other operation");}
	static void f(MyIncrement mi){mi.increment();}
}
class Callee2 extends MyIncrement{
	private int i = 0;
	public void increment(){
		super.increment();
		i++;
		System.out.println(i);
	}
	private class Closure implements Incrementable{
		public void increment(){
			//Specify outer-class method, otherwise you'll get an infinite recursion:
			Callee2.this.increment();
		}
	}
	Incrementable getCallbackReference(){
		return new Closure();
	}
}
class Caller{
	private Incrementable callbackReference;
	Caller(Incrementable cbh){callbackReference = cbh;}
	void go(){callbackReference.increment();}
}
public class Callbacks{
	public static void main(String [] args){
		Callee1 c1 = new Callee1();
		Callee2 c2 = new Callee2();
		MyIncrement.f(c2);
		Caller caller1 = new Caller(c1);
		Caller caller2 = new Caller(c2.getCallbackReference());
		caller1.go();
		caller1.go();
		caller2.go();
		caller2.go();
	}
}

出现的结果为：
Other operation
1
1
2
Other operation
2
Other operation
3
倒数第三个和倒数第1个输出不是为1和2吗，为什么是2和3

谢谢，原来没看到

你在调用 MyIncrement.f(c2); 的时候已经让c2的属性i 变成1 了啊
