本文旨在兩個線程交替運行，不多嗶嗶直接看代碼吧

public class Work2 {
    static final Object object = new Object();

    public static void main(String[] args) {

        Thread t1 = new Thread(new Runnable() {
            @Override
            public void run() {
                synchronized (object) {
                    
 
for (int i = 1; i < 10; i += 2) {
                        System.out.println(Thread.currentThread().getName() + "    " + i);
                        object.notify();
                        try {
                            object.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        }, 
 
"t1");
        Thread t2 = new Thread(new Runnable() {
            @Override
            public void run() {
                synchronized (object) {
                    for (int i = 2; i < 10; i += 2) {
                        System.out.println(Thread.currentThread().getName() + "     " + i);
                        object.notify();
                        
 
try {
                            object.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        }, "t2");
        t1.start();
        t2.start();
    }
}

該實現的原理也非常簡單，定義一個對象，因為一個對象有且只有一個鎖，所以讓兩個線程循環讓此對象解鎖->加鎖，從而達到線程交替運行的目的;

個人覺得此方法還不夠好，後續總結了再繼續補充，還望看到的大佬們多指點指點！

Java兩個線程實現交替運行-以交替打印奇偶數為例
