二、多线程之Thread中run 和start 区别

Thread使用run 和start 区别

结论：run()方法将作为当前调用线程本身的常规方法调用执行，并且不会发生多线程。

System.out.println("开始测试多线程"); Thread thread1= new Thread() { @Override public void run() { for (int i = 0; i < 5; i++) { System.out.println("===Threading count:" + i); } } }; thread1.run(); System.out.println("结束测试多线程");	开始测试多线程 ===Threading count:0 ===Threading count:1 ===Threading count:2 ===Threading count:3 ===Threading count:4 结束测试多线程
System.out.println("开始测试多线程"); Thread thread1= new Thread() { @Override public void run() { for (int i = 0; i < 5; i++) { System.out.println("===Threading count:" + i); } } }; thread1.start(); System.out.println("结束测试多线程");	开始测试多线程 结束测试多线程 ===Threading count:0 ===Threading count:1 ===Threading count:2 ===Threading count:3 ===Threading count:4

System.out.println("开始测试多线程"); new Runnable(){ @Override public void run() { for (int i = 0; i < 5; i++) { System.out.println("===Runnableing count:" + i); } } }.run(); System.out.println("结束测试多线程");

开始测试多线程 ===Runnableing count:0 ===Runnableing count:1 ===Runnableing count:2 ===Runnableing count:3 ===Runnableing count:4 结束测试多线程
