java多线程的使用

public class TestThread implements Runnable{private int i = 0;private int j = 0;public void run() {System.out.println(Thread.currentThread().getName()+"开始运行");System.out.println(i + "+" + j + "=" + (i+j));System.out.println(Thread.currentThread().getName()+"结束运行");}public void setI(int i) {this.i = i;}public void setJ(int j) {this.j = j;}public static void main(String[] args) throws Exception {TestThread testThread = new TestThread();testThread.setI(5);testThread.setJ(10);Thread t = new Thread(testThread,"测试线程");t.start();}}
