      System.out.println("name: "+this.name);
      System.out.println("age: "+this.age);

public class AccessData{
   public static void main(String args[]) {
      //Reading values from user
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter the name of the student: ");
      String name = sc.nextLine();
      System.out.println("Enter the age of the student: ");
      int age = sc.nextInt();
      Student obj1 = new Student(name, age);
