Java代码如何查看对象头和锁状态呢?

Java查看对象头和锁状态的实现思路

借助jol-core这个包
    即可查看对象头和锁状态

<dependency>
	<groupId>org.openjdk.jol</groupId>
	<artifactId>jol-core</artifactId>
	<version>0.9</version>
</dependency>


import org.openjdk.jol.info.ClassLayout;

public class ObjectHeader {
    private static myobject myobject = new myobject();

    public static void main(String[] args) {

        System.out.println("当前MAIN线程开始：
		  " + Thread.currentThread().getName() + "
		  --" + ClassLayout.parseInstance(myobject).toPrintable());

        new Thread(new Runnable() {
            @Override
            public void run() {
                synchronized (myobject) {
                    System.out.println("当前线程：" + Thread.currentThread().getName() + 
					  "--" + ClassLayout.parseInstance(myobject).toPrintable());
                }
            }
        }, "线程1号").start();

        new Thread(new Runnable() {
            @Override
            public void run() {

                synchronized (myobject) {
                    System.out.println("当前线程：
					" + Thread.currentThread().getName() + "--
					" + ClassLayout.parseInstance(myobject).toPrintable());
                }

            }
        }, "线程2号").start();


        System.out.println("当前MAIN线程结束：
		" + Thread.currentThread().getName() + 
		"--" + ClassLayout.parseInstance(myobject).toPrintable());

    }

    static class myobject {
        public myobject() {
        }
    }
}
