Thread: nextLine problems, any help appreciated

so far for my program i have

import java.util.*;
 
public class CalculateChange
{
  public static void main(String[] args)
  {
    String s1, s2;
    Scanner keyboard = new Scanner(System.in);
 
    System.out.print("Enter your name: ");
    s1 = keyboard.nextLine();
 
    System.out.print("Enter current date: "); // in format of mm/dd/yyyy
    s2 = keyboard.nextLine();
 
    String mutation1, mutation2, mutation3;
    mutation1 = s1;
    mutation2 = mutation1.toUpperCase();
    mutation3 = mutation2.substring(0, 1);
 
    System.out.println("===== Ref. # " + mutation3);

i am stuck from here... for the last line it is to print in the format
of ===== Ref. #JSMITH091003 =====
Where the J is the first letter of the name entered for s1 and SMITH is the last
name entered for s1 and then 091003 for the date in format of yy/mm/dd
Note that JSMITH is not what hte user entered just an example of the output and i cant use the Next( ) method

This is what i thought. i cant seem to remember how to do this, if you could explain a bit more, thnx much
