While loop Problem

[WeiNg]

        int AmtOfQuotes = 1;
        //A bit of help? The ! at the front means not.
        while (!Quotes[AmtOfQuotes].equals("")){
            AmtOfQuotes++;
        }
 
        AmtOfQuotes--;
 

These are my code (part). When i compile my whole program, i get:
Exception in thread "main" java.lang.NullPointerException
at QuoteGenerator.main(QuoteGenerator.java:40)
Java Result: 1

Can someone help me?

Are you sure 40th line in QuoteGenerator.java is same as the post you have posted here.?

I'm guessing it's complaining that there is no Quotes[1], so calling that translates to NULL and thus can not be used as a string.

You need to make sure there is actually an element at the position you are asking for before you try to fetch it. - Simplest way to do that is to compare the index you are trying to fetch to the Array.length property. In your case that would read something like:
if(AmtOfQuotes < Quotes.length)

Also consider that Java arrays are zero-indexed, so when you as for Quotes[1] you are actually asking for the second element. If you want to read the whole array, you need to start with 0.

If it has some issues with the array indexes it should throw ArrayIndexOutOfBound exception. Not a null pointer exception.

I guess the value at

Quotes[1]

is null.

I suggest you to display all the values in the array or if you are using any editors (like eclipse) please follow the value of array during array traverse.

An Atli is right Array in Java is Zero indexed. So you may need to fine tune your loop.
