Java多线程基础之对象锁的同步与异步

同步：synchronized

同步的概念就是共享，如果不是共享的资源，就没有必要进行同步。

异步：asynchronized

异步的概念就是独立，相互之间不受到任何制约。

public class MyObject {

public synchronized void method1() throws InterruptedException {
System.out.println(Thread.currentThread().getName());
Thread.sleep(4000);
}
public  void method2(){
System.out.println(Thread.currentThread().getName());
}

public static void main(String[] args) {
final MyObject ob =new MyObject();
Thread t1 =new Thread(new Runnable() {
@Override
public void run() {
try {
ob.method1();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
},"t1");
Thread  t2=new Thread(new Runnable() {
@Override
public void run() {
ob.method2();
}
},"t2");
t1.start();
t2.start();

}
}
