Java 使用5多线程打印数字

我想使用多线程打印一个数字列表

    class RunnableWorker implements Runnable{
    @Override
    public void run() {
        for (int i = 0; i <= 30000; i++) {
            System.out.println(Thread.currentThread().getName() + ": " + i);
        }
    }
    
}
public class RunnableFunctionalInterfaceDemo {
    public static void main(String[] args) {
        Runnable r3 = new RunnableWorker();     
        Thread t3 = new Thread(r3);
        t3.start();
    }
}

类RunnableWorker实现Runnable{ @凌驾 公开募捐{

对于（inti=0；i来说，我不确定您的问题是什么，但是您只需要创建更多的线程，如果这是您想要的

 Runnable r3 = new RunnableWorker();
    Thread t0 = new Thread(r3);
    Thread t1 = new Thread(r3);
    Thread t2 = new Thread(r3);
    Thread t3 = new Thread(r3);
    Thread t4 = new Thread(r3);
    t0.start();
    t1.start();
    t2.start();
    t3.start();
    t4.start();

然而，这将调用为每个线程运行的方法的新实例

看看遗嘱执行人池

class WorkerThread implements Runnable {
private String message;
public WorkerThread(String s){
    this.message=s;
}
public void run() {
    System.out.println(Thread.currentThread().getName()+" || Counter: "+message);
}

}

导入java.util.concurrent.ExecutorService；
导入java.util.concurrent.Executors；
公共类RunnableFunctionalInterfaceDemo{
公共静态void main（字符串[]args）{
ExecutorService executor=Executors.newFixedThreadPool（4）；//创建一个包含4个线程的池
对于（int i=0；i<1000；i++）{
Runnable worker=新WorkerThread（“+i”）；
executor.execute（worker）；//调用ExecutorService的execute方法
}
executor.shutdown（）；
}
}

您的问题是什么？请阅读我们的页面和您的问题以改进它。好的问题往往会从社区得到更快、更好的答案。当我使用0-30000的全线程打印时，我希望打印出来而不重复。我希望打印出来，就像以下线程1…………线程2…………线程3…………线程4。。。。。。…线程5 1…2…3…4…5 6…7…8…9…10您应该查找Executor线程池！

  import java.util.concurrent.ExecutorService;
    import java.util.concurrent.Executors;

    public class RunnableFunctionalInterfaceDemo {
    public static void main(String[] args) {
        ExecutorService executor = Executors.newFixedThreadPool(4);//creating a pool of 4 threads
        for (int i = 0; i < 1000; i++) {
            Runnable worker = new WorkerThread("" + i);
          executor.execute(worker);//calling execute method of ExecutorService
        }
        executor.shutdown();
    }
}
