java. 中 继承Thread类创建线程.
package pack.java.thread;/** * 继承Thread类; * @author Administrator * */public class ThreadDemo extends Thread{int k = 0; //初始值;public ThreadDemo(){super();}public ThreadDemo(int i,String name){super(name);this.k= i ;}@Overridepublic void run() {// TODO Auto-generated method stubint i = k;while (i<50) {System.out.println("i->"+i);i +=2;}System.out.println(getName()+"end!");}public static void main(String []args) {//创建线程对象1;ThreadDemo threadDemo1= new ThreadDemo(1, "ZhouHaiTao");//启动线程1;threadDemo1.start();//创建线程对象2;ThreadDemo threadDemo2 = new ThreadDemo(2, "PengXiaoTing");//启动线程2;threadDemo2.start();System.out.println("\n活动的线程数:"+activeCount());}}
