也就是说，并不是Thread一定要实现Runnable，而是有了Runnable这个概念后，发现Thread的某一种用法刚好符合...
2、实现Runnable接口 定义一个类,实现Runnable接口,重写run方法,run方法包含了线程执行的任务; 创建这个类对象,然后再创建相应数量的Thread对象,作为代理,将Runnable接口对象传入Thread对象中,然后调用Thread对象的start方法启动线程。启动的过程就是先初始化线程对象将传入的Runable接口对象赋予target成员变量,然后执行run方法...
public static void main(String[] args) { Thread t1 = new Thread(new HeavyWorkRunnable(), "t1"); Thread t2 = new Thread(new HeavyWorkRunnable(), "t2"); System.out.println("Starting Runnable threads"); t1.start(); t2.start(); System.out.println("Runnable Threads has been started")...
1.2. By ImplementingRunnableInterface Implementing theRunnableinterface is considered a better approach because, in this way, the thread class can extend any other class. Remember, in Java, a class can extend only one class but implement multiple interfaces. classSubTaskWithRunnableimplementsRunnable{pu...
方法二:Implementing java.lang.Runnable 通过实现java.lang.Runnable接口,亦可以定义一个thread,示例如下: class MyRunnable implements Runnable { public void run() { System.out.println("Important job running in MyRunnable"); } } 注意:因为是implements一个interface,因此你必须实现其public void run();方法...
reality , you do not need Thread class behavior , because in order to use a thread you need to instantiate one anyway. On the other hand, Implementing the Runnable interface gives you the choice to extend any class you like , but still define behavior that will be run by separate thread...
If your class provides more functionality rather than just running as Thread, you should implement Runnable interface to provide a way to run it as Thread. If your class only goal is to run as Thread, you can extend Thread class. Implementing Runnable is preferred because java supports impleme...
public class Thread implements Runnable { //省略2000多行代码... } 1. 2. 3. Thread类本身实现了Runable接口。 继续查看JDK源码中的Runnable接口是怎么写的。 @FunctionalInterface public interface Runnable { /** * When an object implementing interface Runnable is used * to create a...
1. Getting Thread Name By default, the Java compiler sets a default name of each threadwhile creating, and we can get the thread name by using theThread.currentThread().getName()method. In the following example, we created aThreadby implementing theRunnableinterface and itsrun()method. This...
一句话,Runnable是接口,Thread 继承了Runnable, 它们都有run()方法。 public interface Runnable { /** * When an object implementing interface Runnable is used * to create a thread, starting the thread causes the object's * run method to be called in that separately executing * thread. *...
