class Demo{
public static void main(String[] args){
Thread t=new Thread();
t.start;
}
}
class Threads extends Thread{
public void run(){
System.out.println("java学习");
}
}

class Demo{
Runables r=new Runables();
Thread t=new Thread(r);
t.start;
}
class Runnables implements Runnable{
public void run(){
System.out.println("java学习");
}
}

Thread t = new Thread(new Runnable() {
public void run() {
for (int i = 1; i <= 10; i++) {
System.out.println(i++);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
