簡單的multithread

很久沒有寫過programme，連一些很簡單的Java Syntax也要Google，真的要練習練習~

// CounterThread.java
// 1st Argument = No Of Threads
// 2nd Argument = Counter Value 

public class CounterThread extends Thread {

    public static int counterValue = 0;

    public void run(){
        for (int i = 0; i < counterValue  ;i++){
            System.out.println(Thread.currentThread().getName() + "\t" + i);
        }
    }

    public static void main(String arg[]){
        if (arg.length==2){
            int noOfThreads = Integer.parseInt(arg[0]);
            counterValue = Integer.parseInt(arg[1]);

            CounterThread [] ct = new CounterThread[noOfThreads];
            System.out.println("No Of Threads = " + noOfThreads);
            System.out.println("Counter Value = " + counterValue);

            for (int i = 0; i < noOfThreads ; i++){
                ct[i] = new CounterThread();
                ct[i].start();
            }
        }
        else{
            System.out.println("Argument incorrct!!");
        }
    }
}
