Java——线程同步代码优化

此博客意在优化之前几篇博客的代码，使得变量私有化，具体如下

class Res{ 
        private String name;
        private String sex;
        private boolean flag;
    
        //存储数据
        public synchronized void set(String name,String sex){
            if(flag){
    
                try{
       this.wait();}catch(InterruptedException e){e.printStackTrace();}
            }
            this.name = name;
            this.sex = sex;
            flag= true;
            notify();
        }
        //输出数据
        public synchronized void out(){
            if(!flag){
                try{
       this.wait();}catch(InterruptedException e){e.printStackTrace();}
            }
            System.out.println(name+"...."+sex);
            flag = false;
            notify();
        }
    }
    //输入任务
    class Input implements Runnable{ 
        private Res res;
        public Input(Res res){
            this.res = res;
        }
        public void run(){
            int i = 1;
            while(true){
                if(i==1){
                    res.set("张三","男");
                }else{
                    res.set("李四","女");
                }
                i = (i+1)%2;
            }
        }
    }
    //输出任务
    class Output implements Runnable{ 
        private Res res;
        public Output(Res res){
            this.res = res;
        }
        public void run(){
            while(true){
                res.out();
            }
        }
    }
    
    class test{ 
        public static void main(String[] args){
            Res res = new Res();
    
            Input in = new Input(res);
            Output out = new Output(res);
    
            Thread t1 = new Thread(in);
            Thread t2 = new Thread(out);
    
            t1.start();
            t2.start();
        }
    }
