如何在 Java 中创建线程
java 8object oriented programmingprogramming
可以通过实现 Runnable 接口并重写 run() 方法来创建线程。然后可以创建一个 Thread 对象并调用 start() 方法。
Java 中的主线程是在程序启动时开始执行的线程。所有子线程都是从主线程生成的，它是最后一个完成执行的线程。
下面给出了一个演示此操作的程序:
示例
class ThreadDemo implements Runnable {
Thread t;
ThreadDemo() {
t = new Thread(this, "Thread");
System.out.println("Child thread: " + t);
t.start();
}
public void run() {
try {
System.out.println("Child Thread");
Thread.sleep(50);
} catch (InterruptedException e) {
System.out.println("The child thread is interrupted.");
}
System.out.println("Exiting the child thread");
}
}
public class Demo {
public static void main(String args[]) {
new ThreadDemo();
try {
System.out.println("Main Thread");
Thread.sleep(100);
} catch (InterruptedException e) {
System.out.println("The Main thread is interrupted");
}
System.out.println("Exiting the Main thread");
}
}
输出
Child thread: Thread[Thread,5,main] Main Thread Child Thread Exiting the child thread Exiting the Main thread
