import java.util.Scanner;

public class StudentInfo {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter firstName: ");
       String fname = sc.nextLine();
       System.out.println("Enter age: ");
       int age = sc.nextInt();
       System.out.println("Enter lastName: ");
       String lname = sc.nextLine();
       lname = sc.nextLine();
       //adding fname and lname to make full name
       String name = fname + lname;
       //printing number of chars in full name
       System.out.println("Total Number of chars in name: " + name.length());
       //printing name in uppercase
       System.out.println("Name (Upper): " + name.toUpperCase());
       //printing in lower case
       System.out.println("Name (lower): " + name.toLowerCase());
       //printing first char using charAt()
       System.out.println("First letter: " + name.charAt(0));
       System.out.println("Age: " + age);

   }
