Java Thread 的 run() 与 start() 的区别(2)

public class Test { public static void main(String[] args) { Runner1 runner1 = new Runner1(); Runner2 runner2 = new Runner2(); // Thread(Runnable target) 分配新的 Thread 对象。 Thread thread1 = new Thread(runner1); Thread thread2 = new Thread(runner2); // thread1.start(); // thread2.start(); thread1.run(); thread2.run(); } } class Runner1 implements Runnable { // 实现了Runnable接口，jdk就知道这个类是一个线程 public void run() { for (int i = 0; i < 100; i++) { System.out.println("进入Runner1运行状态——————————" + i); } } } class Runner2 implements Runnable { // 实现了Runnable接口，jdk就知道这个类是一个线程 public void run() { for (int i = 0; i < 100; i++) { System.out.println("进入Runner2运行状态==========" + i); } } }
