java 多线程

多线程：
1.implements Runnable
2.extends Thread

package com.lhj.java;

public class Test {
public static void main(String[] args) throws Exception {
new Thread(new RRR()).start();

for (int i = 1; i <= 100; i++) {
System.out.println("main......."+i);
}

}
}

class RRR implements Runnable{      //或改成extends Thread

public void run() {
for(int i=1000;i<=1100;i++){
System.out.println("run---------"+i);
}
}

}
