多线程创建方式
1、继承Thread
public class ThreadTest {
public static void main(String[] args) {
MyThread myThread = new MyThread();
myThread.start();
for (int i = 0; i < 1001; i++) {
if(i % 2 != 0){
System.out.println(i + "main");
}
}
}
}
class MyThread extends Thread{
@Override
public void run() {
for (int i = 0; i < 1001; i++) {
if(i % 2 == 0){
System.out.println(i);
}
}
}
}
Thread.currentThread()获取当前线程，setName getName 设置线程名称
if (i ==20){
myThread.join();
}
当前线程进入阻塞，等myThread线程执行完了再执行
2、实现runaable接口
public class ThreadTest1{
public static void main(String[] args) {
MyThread1 myThread1 = new MyThread1();
Thread thread = new Thread(myThread1);
thread.start();
for (int i = 1001; i < 2000; i++) {
System.out.println(Thread.currentThread().getName()+i);
}
}
}
class MyThread1 implements Runnable{
@Override
public void run() {
for (int i = 0; i < 1000; i++) {
System.out.println(Thread.currentThread().getName()+i);
}
}
}
