String and char arrays

[leeroijenkiins]

I really dont know why this isnt working, maybe someone could shed some light on it for me; as i dont use chars very often nor do i relate strings to each other often.

		for (int i = 0; i < 5; i++){
			if (s.equals(perfectNames[i])){
				score = 10;
				break;
			}
			if(s.equals(worstNames[i])){
				score = 0;
				break;
			}
		}
		
		for(int i = 1; i < s.length(); i++){
			letter = s.charAt(i);
			for(int a = 0; a <= vowels.length; a++){
				if(letter == vowels[a]){
					score++;
				}
			}
			for(int b = 0; b <= startingL.length; b++){
				if(letter == startingL[b]){
					score++;
				}
			}
		}
		}

my error:

Enter any name: rob
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
	at NameTest.grading(NameTest.java:32)
	at NameTest.main(NameTest.java:17)

So what im trying to make is a name test; you write a name and it tells you how good of a name it is.
I would have thought this code is right; there is no errors until you type a name in.
oh and this error:

	at NameTest.grading(NameTest.java:32)

refers to this line of code:

if (s.equals(perfectNames[i])){

but its also given me errors when i comment that code out at this part:

if(letter == vowels[a]){

any ideas?

its telling you that you are trying to add into the array at an index that doesn't exist.

try this:

Replace: references to the arrayLength so:

startingL.length; would become startingL.length -1;

vowels.length; would become vowels.length -1;

Give that a whirl.

Just change your relational operator from <= to <. Also, do you really want to begin for loop @ line 12 with i = 1? I can't tell with the posted code.

Thank you that fixed the problem for that part. another issue if you can help:

for (int i = 0; i < 5; i++){
			if (s.equals(perfectNames[i])){
				score = 10;
				break;
			}
			if(s.equals(worstNames[i])){
				score = 0;
				break;
			}
		}

its not breaking out of this loop for some reason ..
if it is one of the perfectNames or worstnames it works but if its not i get an error with this line:

if (s.equals(perfectNames[i])){

tried adding this to make it break out but it doesnt work for some reason

			if(i == 4){
				if(!s.equals(worstNames[i])){
					break;
				}
			}

THANKS
