关于以下程序代码的说明正确的是?()

   public class HasStatic{

     private static int x=100;

     public static void main(String args[]){

          HasStatic hs1=new HasStatic();

          hs1.x++;

          HasStatic  hs2=new HasStatic();

          hs2.x++;

          hs1=new HasStatic();

          hs1.x++;

        HasStatic.x--;

        System.out.println("x="+x);

     }

   }
