我有一段这样的代码
Dotry try1=new Dotry("线程1");
Dotry try2=new Dotry("线程2");
try1.start();
try1.join();
Thread.sleep(2000);
try1.wait();
try2.start();
调试后报错我想问一下时怎么回事啊？
class Dotry extends Thread{
String name;
public Dotry(String name){
this.name=name;
}
public void run(){
for(int i=15;i>0;i--){
System.out.println(name+"在运行");
}
}
}
