      {  
           int total=0;  
           int a=0;  
           int num=4321;  
           for(int x=0;x<4;x++)  
           {  
                a=num/10;  
                num=num/10;  
                System.out.println(a);  
                total +=a;  
           }  
                System.out.println(total);
