 {
  roll = r;
  name=nm;
  cnt++;
  System.out.println("Counter= "+cnt);
 }
 public String toString()
 {
  return("Roll no "+roll+" Name= "+name+" Percentage= "+per);
 }
 public static void main(String args[])
 {
  Student s1= new Student (1,"Rohit",65.12);
  System.out.println(s1);
  Student s2= new Student (2,"Pranav",61.12);
  System.out.println(s2);
  Student s1= new Student (1,"Aditya",68.12);
  System.out.println(s1);
  System.out.println("Number of students: "+cnt);
