java多线程实现奇偶数输出

两种实现方式1：普通synchronized版实现、 2：使用Semaphore版实现
一：普通synchronized版实现

在这里插入代码片public class Ceshi999 {
    static int result = 0;

    public static void main(String[] args){
        Thread thread = new Thread(new Jiou(0));
        thread.start();
        Thread thread1 = new Thread(new Jiou(1));
        thread1.start();
    }
    static class Jiou implements Runnable{
        private int i;
        public Jiou(int i){
            this.i = i;
        }
        @Override
        public void run() {
            while (result<100){
                synchronized (Jiou.class){
                    System.out.println("thread"+i+":"+result++);
                    Jiou.class.notify();
                    try {
                        Jiou.class.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }
    }
}

二：使用Semaphore版实现

public class Ceshi888 {
    static  int result = 0;
    public static void main(String[] args) throws InterruptedException {
        int N = 3;
        Thread threads[] = new Thread[N];//声明N个数据
        Semaphore semaphore[] = new Semaphore[N];//声明N个信息号量
        for(int i=0;i100){
                                System.exit(0);
                            }
                        }catch (Exception e){
                            e.printStackTrace();
                        }finally {
                            currentSemphore.release();
                        }
                    }
                }
            });
            threads[i].start();
        }
    }
}
