public class Run implements Runnable{
@Override
public void run() {
String threadName = Thread.currentThread().getName();
System.out.println("当前线程 "+threadName);
}
public static void main(String[] args) {
new Thread(new Run()).start();
}
}
public class Run extends Thread{
@Override
public void run() {
String threadName = Thread.currentThread().getName();
System.out.println("当前线程 "+threadName);
}
public static void main(String[] args) {
new Thread(new com.kongdechang.stu.Run()).start();
}
}
public class Run {
public static void main(String[] args) {
new Thread(()->{
String threadName = Thread.currentThread().getName();
System.out.println("当前线程 "+threadName);
}).start();
new Thread(new Runnable() {
@Override
public void run() {
String threadName = Thread.currentThread().getName();
System.out.println("当前线程 "+threadName);
}
});
}
}
public class Run implements Callable<String> {
@Override
public String call() throws Exception {
String threadName = Thread.currentThread().getName();
System.out.println("当前线程 "+threadName);
return threadName;
}
public static void main(String[] args) throws ExecutionException, InterruptedException {
Callable<String> callable = ()->{
String threadName = Thread.currentThread().getName();
System.out.println("当前线程 "+threadName);
return threadName;
};
//获取线程池,执行线程数量
ExecutorService es = Executors.newFixedThreadPool(2);
//提交线程任务
es.submit(new Run());
es.submit(new Run());
es.submit(new Run());
es.submit(callable);
// 接收返回值
Future<String> future = es.submit(callable);
//关闭线程池
es.shutdown();
System.out.println(future.get());
}
}

---无人问津也好，技不如人也罢，你都要试着安静下来，去做自己该做的事，而不是让内心的烦躁、焦虑，坏掉你本来就不多的热情和定力
