A：Thread

简简单单

Thread t = new Thread() {
	@Override
	public void run() {
		log.info(1);
	}
};
t.start();

B：Runnable

分离任务与线程

Runnable run = new Runnable() {
	@Override
	public void run() {
		log.info(1);
	}
};
new Thread(run).start();

C：FutureTask

获取任务结果

FutureTask<Integer> task = new FutureTask<>(new Callable<Integer>() {
	@Override
	public Integer call() throws Exception {
		log.info(1);
		return 2;
	}
});
new Thread(task).start();
log.info(task.get());//会阻塞直到返回结果
