How to run 10+ threads in java without repetitive code?

Question

Java

How to run arbitrary number of threads? Now for 5 threads you have to use

Thread t1 = new myThread();
            Thread t2 = new myThread();
            Thread t3 = new myThread();
            Thread t4 = new myThread();
            Thread t5 = new myThread();
            t1.start();
            t2.start();
            t3.start();
            t4.start();
            t5.start();
            t1.join();
            t2.join();
            t3.join();
            t4.join();
            t5.join();

Answer 1

Something like this....

ArrayList<Thread> mythreads = new ArrayList<Thread>();
int tcount = 1000;
for(int i=0; i< tcount; i++) {
     Thread thr = new myThread();
     mythreads.add(thr);
     thr.start();
}
for (Thread thr : mythreads) {
     thr.joint();
}

or fashionable

ExecutorService es = Executors.newCachedThreadPool();
for(int i=0;i<5000;i++)
    es.execute(new Runnable() { /*  your task */ });
es.shutdown();
boolean finshed = es.awaitTermination(1, TimeUnit.MINUTES);

It seems to me that there is exhaustive information here, tutorials.jenkov.com/java-concurrency/thread-pools.html
Either stupidly the same as what you are doing but in a loop.
