public static void main(String[] args)
{
    Thread thread = new Thread(new Task());
    thread.start();
    
    // 中断线程
    thread.interrupt(); 
    System.out.println("exit main thread.");
}

/*
result:
exit main thread.
do sth.
interrupted!
*/

Join.java

public static void main(String[] args) throws InterruptedException
{
    Thread thread = new Thread(new Task());
    thread.start();

    // 等待thread终止
    thread.join();

    System.out.println("exit main thread.");
}

/*
result:
do sth.
exit main thread.
*/

Start.java

public static void main(String[] args) throws InterruptedException
{
    Thread thread = new Thread(new Task());
    
    // 启动线程
    thread.start();

    System.out.println("exit main thread.");
}
    
/*
result:
exit main thread.
do sth.
*/

Task.java

class Task implements Runnable
{
    @Override
    public void run()
    {
        try
        {
            System.out.println("do sth.");

        }
        catch (InterruptedException e)
        {
