本文探讨了并发编程的基本概念，通过实现简单的多线程程序展示了如何利用多线程提高程序性能。从线程创建、运行到线程间通信，深入浅出地介绍了并发编程的实践技巧。

public class TestThread1 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
for(int i=0;i<10;i++){
new Thread(new AAA1(i)).start();
}
}
}
class AAA1 implements Runnable{
int i;
AAA1(int ii){
i=ii;
}
@Override

System.out.println("count "+i+ " "+Thread.currentThread().getName()+" AAA1"+Thread.currentThread().getThreadGroup());
