Thread: Making a string lowercase

Hi I currently have to develop a application for my basic level java programming class, that takes a first, last and middle name entered. Then takes the first letter from first name, and middle name, and the first 4 letters of last name, and then adds a random generated number from 100-999 for a username.

For example:

If I entered: Raymond Jason Smith
It would return: RJSmit222

I need help on making all my generated username display in lowercase only, no matter if user enters it in uppercase

import java.util.Random; 
import java.util.Scanner;
 
 
 
    public class random {
 
    public static void main (String[] args) {
	Scanner scan = new Scanner(System.in);
    Random random = new Random();
 
	String first;
	String middle;
	String last;
 
	    System.out.print ("First name? "); //prompts user for first name
		first = scan.nextLine ();
		System.out.print ("Middle name? "); //prompts user for middle name
		middle = scan.nextLine ();
	    System.out.print ("Last name? "); //prompts user for last name
		last = scan.nextLine ();
 
		System.out.println ("\nInputed first name was: " + first); //tells user inputed data - first name
		System.out.println ("Inputed middle name was: " + middle);//tells user inputed data - middle name
		System.out.println ("Inputed last name was: " + middle); //tells user inputed data - last name
 
		int randomNumber = random.nextInt(899) + 100; //random generated number from 100-999 for username
	    System.out.println ("Random computer generated number: " + randomNumber); //Tells user the generated number
 
		System.out.print ("\nYour generated username is: " + first.charAt(0) 
		                                  + middle.charAt(0) 
									      + last.substring (0, 4) 
										  + randomNumber); //echo generated username
 
 
    }
}

HI,

U can use something like this

 System.out.print ("\nYour generated username is: " + first.toLowerCase().charAt(0)
                                          + middle.toLowerCase().charAt(0)
                                          + last.toLowerCase().substring (0, 4)
                                          + randomNumber); //echo generated username

Hey I appreciate all the help guys.
