package com.lin;
//外部类
public class GroupThree {
    private static int count;
    private String name;
   //内部类
    public class Student{
        private int count;
        private String name;
        
        public void Output(int count){
            count++;  //6
            this.count++;   //1
            GroupThree.count++; //12
            
            GroupThree.this.count++;//12
            System.out.println(count+" "+this.count+" "+
                    GroupThree.count+" "+GroupThree.this.count);
        }
    }
    public static void main(String[] args) {
        
        GroupThree g=new GroupThree();
        g.count=10;
        //用外部类创建内部类的格式
        GroupThree.Student s=new GroupThree().new Student();
        
        s.Output(5);
        
    }

}
运行结果是：6 1 12 12 。
问题：怎么GroupThree.count++;执行的结果是12，不是11吗？真搞不懂啊。
            
    GroupThree.this.count++;//12 这个和上面的语句如何理解啊？求大侠帮帮忙，小弟不才啊！！
