创建线程的几种方法

Thread thread = new Thread(){
@Override
public void run() {
while(true){
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("1---->" + Thread.currentThread().getName());
}
}

};
thread.start();

/**
* 第二种通过Runnable接口创建
*/
Thread thread2 = new Thread(new Runnable(){
@Override
public void run() {
while(true){
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("2---->" +Thread.currentThread().getName());
}
}

});
thread2.start();

/**
* 第三種 通過Thread子類創建和通過Runnable创建
* 两种方式并存的时候系统会调用实现子类的run的那个线程，会把实现接口的那个线程覆盖，和面向对象的重写思路一样。
*/
new Thread(new Runnable(){
//Thread子类创建
@Override
public void run() {
while(true){
try {
Thread.sleep(500);
