Java programming help Plz

Thank youu. The .charAt worked but I still have a problem. I need to know how many characters are in each string now so I can test each string's characters if they are lowercase. This is what I have so far for that portion...but I get a String Index Out Of Bounds Exception:

for (i=0; i<30; i++){ if (Character.isLetterOrDigit(LastName.charAt(i))){ LastChar_count++; } else{ break; } } for (i=0; i<30; i++){ if (Character.isLetterOrDigit(FirstName.charAt(i))){ FirstChar_count++; } else{ break; } }

I just need to count the number of characters.

You can use the String method length() to determine how many characters there are in a string object. For instance, you may want to use something like for(int i=0; i < LastName.length(); i++) to iterate through each character in the string LastName.

Thanks, I realized I could use the .length like ten minutes after posting this Lol. I finished the program and it works nicely. Thanks for your help

If you want to see if all the characters in a string are lowercase, for String str, then you can do the following

if(str.compareTo(str.toLowerCase())!=0) { // do this if the string is not lower case } else { // do this if string is lower case }

No loops necessary.
