In "implements Runnable" , we are creating a different Runnable class for a specific behavior job (if the work you want to be done is job). It gives us the freedom to reuse the specific behavior job whenever required. "extends Thread" contains both thread and job specific behavior code. ...
而继承Runnable接口则不一样,多个线程共享一个对象。 用一个例子来帮助我们理解: 1classImplementsRunnableimplementsRunnable {23privateintcounter = 0;45publicvoidrun() {6counter++;7System.out.println("ImplementsRunnable : Counter : " +counter);8}9}1011classExtendsThreadextendsThread {1213privateintcounter...
b:是实现Runnable接口。 public class ThreadDemo2 implements Runnable { public void run(){ //Thread.currentThread().getName() 和 this.getName()都可以用来获得线程的名称 System.out.println("线程的名称:"+Thread.currentThread().getName()); } public static void main(String[] args) { ThreadDemo2...
当我们做这个系统的时候可能会想到两种方式来实现,继承Thread类或实现Runnable接口,现在看一下这两种方式实现的两种结果。 代码语言:javascript 代码运行次数:0 AI代码解释 publicclassTheadDemoextendsThread{privateint ticket=10;privateString name;publicTheadDemo(String name){this.name=name;}publicvoidrun(){for(i...
继承Thread VS 实现 Runnable 区别 从java的设计来看,通过继承Thread或者实现Runnable接口来创建线程本质上没有区别,从jdk帮助文档可以看到Thread类本身就实现了Runnable接口 实现Runnable接口方式更加适合多个线程共享一个资源的情况,并且避免了单继承的限制,建议使用Runnable。
In Java, there are two ways to create threads i.e. implementingRunnableinterface and extendingThreadclass. In this Java concurrency tutorial, we will identify the differences between both ways i.e.extends thread Vs. implements runnable. In general, until we have a particular reason, it is alway...

ThreadPoolExecutor的构造方法包含7个核心参数: public ThreadPoolExecutor( int corePoolSize, // 核心线程数 int maximumPoolSize, // 最大线程数 long keepAliveTime, // 空闲线程存活时间 TimeUnit unit, // 时间单位 BlockingQueue<Runnable> workQueue, // 任务队列 ...
//ScheduledExecutorService实现了ExecutorService接口 public class ScheduledThreadPoolExecutor extends ThreadPoolExecutor implements ScheduledExecutorService ③. 异步计算的结果(Future) Future 接口以及 Future 接口的实现类 FutureTask 类都可以代表异步计算的结果。 当我们把 Runnable接口 或Callable 接口 的实现类提交给 ...
