 public static void main(String args[])
 {
  int i,a=0,r1=0,r2=0,r3=0,r4=0;
  Scanner rd = new Scanner(System.in);
  System.out.println("Enter 10 student mark:");
  for(i=0;i<10;i++)
  {
   a = rd.nextInt();
   if(a>=0 && a<=40)
   r1++;
   else if(a>40 && a<=60)
   r2++;
   else if(a>60 && a<=80)
   r3++;
   else if(a>80 && a<=100)
   r4++;
  }
  System.out.println("Mark between 0 and 40 = "+r1);
  System.out.println("Mark between 40 and 60 = "+r2);
  System.out.println("Mark between 60 and 80 = "+r3);
  System.out.println("Mark between 80 and 100 = "+r4);
 }
