1.创建线程
在Java中创建线程有两种方法：使用Thread类和使用Runnable接口。在使用Runnable接口时需要建立一个Thread实例。因此，无论是通过Thread类还是Runnable接口建立线程，都必须建立Thread类或它的子类的实例。Thread构造函数：
public Thread( );
public Thread(Runnable target);
public Thread(String name);
public Thread(Runnable target, String name);
public Thread(ThreadGroup group, Runnable target);
public Thread(ThreadGroup group, String name);
public Thread(ThreadGroup group, Runnable target, String name);
public Thread(ThreadGroup group, Runnable target, String name, long stackSize);
方法一：继承Thread类覆盖run方法
public class ThreadDemo1 {
public static void main(String[] args){
Demo d = new Demo();
d.start();
for(int i=0;i<60;i++){
System.out.println(Thread.currentThread().getName()+i);
}
}
}
class Demo extends Thread{
public void run(){
for(int i=0;i<60;i++){
System.out.println(Thread.currentThread().getName()+i);
}
}
}
方法二：
public class ThreadDemo2 {
public static void main(String[] args){
Demo2 d =new Demo2();
Thread t = new Thread(d);
t.start();
for(int x=0;x<60;x++){
System.out.println(Thread.currentThread().getName()+x);
}
}
}
class Demo2 implements Runnable{
public void run(){
for(int x=0;x<60;x++){
System.out.println(Thread.currentThread().getName()+x);
}
}
