So heres my code. I have 2 instructors fighting each other and there will be mulitple rounds for them.
I want a battle(round) to be threaded.
Now when i run this, i get a symbol not found error for the while loop for the instructor1 and instructor2. Im assuming my understanding for the run() method isnt clear. Can you help me figure it out?

你必须将Object instructor1和Object instructor2声明为全局变量，并在构造函数中进行初始化，以便它们可以在不同的方法中访问。
public class Battle extends Thread{
private Object instructor1;
private Object instructor2;
public Battle(Object instructor1, Object instructor2){
this.instructor1 = instructor1;
this.instructor2 = instructor2;
}
}
英文:
You have to declare Object instructor1, Object instructor2 as a global variable and initialize them in constructor in order for them to access on different methods.
public class Battle extends Thread{
private Object instructor1;
private Object instructor2;
public Battle(Object instructor1, Object instructor2){
this.instructor1=instructor1;
this.instructor2=instructor2;
}
}
