3.准备一段Java代码

public class Visibility 

    private static volatile boolean  flag = true;
    public static void main(String[] args) throws InterruptedException 
        new Thread(() -> 
            while (flag) 

            
        ).start();
        TimeUnit.SECONDS.sleep(1);

        new Thread(() -> 
            flag = false;
            System.out.println(Thread.currentThread().getName() + "线程将flag修改为了false!");
        ).start();
    

4.配置参数

-XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly
