need help uppercasing names that were input

[jbajwa1]

I can get the first letter of the first name to Capitalize. Then I can get the first letter of the last name to capitalize. My problem is that if the user only inputs a first name then the program can not find a "space" so it gives an error. Is there another way to find a second name? Is there something simple I'm missing?

the line in bold is the one that searches for that space and causes it to fail if there isn't a space

Java code:

private static String enterName()
{
String name = new String(JOptionPane.showInputDialog(null, "What is the name of the new customer:", "INPUT NAME", JOptionPane.QUESTION_MESSAGE));
name = name.trim();

String firstLetter = new String(name.substring(0,1));

firstLetter = firstLetter.toUpperCase();

name = firstLetter.concat(name.substring(1,name.length()) );

String lastNameTest = new String(name.substring(name.indexOf(' ')));

int lastNameTestInt = lastNameTest.length();

JOptionPane.showMessageDialog(null, lastNameTestInt);

if (lastNameTestInt > 0)
{
String firstLetterofLastName = new String(name.substring(name.indexOf(' '), name.indexOf(' ')+2));

firstLetterofLastName = firstLetterofLastName.toUpperCase();

name = name.substring(0, name.indexOf(' ')) + firstLetterofLastName + name.substring(name.indexOf(' ')+2, name.length());
}

return name;
}

Here's the error message:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -1

The error message is telling you that it cannot access the index of a string at index of -1. Check out the String API for the methods you're using.
