    Default 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
