Java中线程Thread的三种方式和对比

public class ThreadPattern extends Thread {
    @Override
    public void run() {
        System.out.println("继承Thread当前执行线程"+Thread.currentThread().getName());
    }
}
// 测试
public void threadTest() throws ExecutionException, InterruptedException {
        ThreadPattern pattern = new ThreadPattern();
        pattern.start();
    }

public class RunnablePattern implements Runnable{
    @Override
    public void run() {
        System.out.println("实现Runnable方式,当前执行线程"+Thread.currentThread().getName());
    }
}
// 测试
public void runnableTest() throws ExecutionException, InterruptedException {
        RunnablePattern runnablePattern = new RunnablePattern();
        Thread thread = new Thread(runnablePattern);
        thread.start();
    }

public class CallablePattern  implements Callable {
    @Override
    public Object call() throws Exception {
        System.out.println("实现Callable方式,当前执行线程"+Thread.currentThread().getName());
        return "1";
    }
}
// 测试
public void callableTest() throws ExecutionException, InterruptedException {
        CallablePattern callablePattern = new CallablePattern();
        FutureTask<String> futureTask = new FutureTask<>(callablePattern);
        new Thread(futureTask).start();
    }
