Loop-y Blah

Say I need to type in my name - letter by letter, and then concatenate the input to form the whole name. All the while I am checking for numbers and marking for errors.

So for my first name, entered in as a string I have it down pat and it seems to be working fine. but i can't figure out how to have each letter entered in and then join them together



Scanner keyboard = new Scanner(System.in);
System.out.println("What is your first name?");
firstName = keyboard.nextLine();
for(i=0; i<firstName.length();i++)
{
ch=firstName.charAt(i);
if (!(ch>=65 && ch <=90))
{
if(!(ch>=97 && ch<=122))
{
flag=1;
System.out.println("You've entered in an invalid name");
break;
}
}
}
System.out.println("Enter in your last name, letter by letter");

If you have a valid firstName and a valid lastName you can join the two together as follows:

String firstName= ...;
String lastName= ...;
String completeName= firstName+" "+lastName;

But your question raises another question: what are those numbers 65, 90, 97 and 122 doing in your code?

kind regards,

Thanks for the reply, what I need to do though is enter in my last name, character by character

s (enter)
m(enter)
i (enter)
and so on

and then add all the letters together to form the whole last name.
