Java多线程实现......(1,继承Thread类)

MyThread.java 中的代码:

public class MyThread extends Thread{
    private int startPrint,printCount;
    private String threadName;

    public MyThread(int startPrint ,int printCount ,String threadName){
        this.startPrint = startPrint;
        this.printCount = printCount;
        this.threadName = threadName;
    }
    public void run(){
        for(int i=0 ;i<printCount ;i++){
            System.out.println(threadName + ":" + (i + startPrint));
        }
    }
}

MainThread:

public class MainThread{
    public static void main(String[] args){
        MyThread mt1 = new MyThread(1   ,100 ,"Thread 1 ");
        MyThread mt2 = new MyThread(100 ,120 ,"Thread 2 ");

        mt1.start();
        mt2.start();
    }
}
