程序代码：

class A implements Runnable{ 
       public int i = 1; 
       public void run(){ 
        this.i = 10; 
    System.out.println(i);
       } 
  } 
public class Test{ 
  public static void main(String args[]){
      A a = new A(); 
    new Thread(a).start() ;
    
      int j = a.i; 
System.out.println(j);
 }
}
