昨天看了基础视频的等待唤醒机制的代码优化 为什么会出现编译错误 我调了好长时间调不出来
- class Res
- {
- private String name;
- private String sex;
- boolean flag=false;
- public synchronized void set(String name,String sex){
- if(flag)
- try{this.wait();}catch(Exception e){}
- this.name=name;
- this.sex=sex;
- flag=true;
- this.notify();
- }
- public synchronized void out(){
- if(!flag)
- try{this.wait();}catch(Exception e){}
- System.out.println(name+"...."+sex);
- flag=false;
- this.notify();
- }

- }
- class Input implements Runnable

- Input(Res r){
- this.r=r;
