如何暂停代码，以便它可以完成其他代码，然后继续

console.log("Start");
setTimeout(function() {
  console.log("Hello World");
}, 1000);
console.log("End");

console.log("Start");

async function pause() {
  await new Promise(resolve => setTimeout(resolve, 1000));
  console.log("Hello World");
}

pause();

console.log("End");

public class CodePauseExample {
    public static void main(String[] args) {
        System.out.println("Start");

        Object lock = new Object();

        Thread pauseThread = new Thread(() -> {
            synchronized (lock) {
                try {
                    lock.wait(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                System.out.println("Hello World");
            }
        });

        pauseThread.start();

        System.out.println("End");
    }
}
