Your trying to access/use something that has not been defined/initialised yet. The full error message, and highlighting of the line referenced in the error message would help.

I would imagine you are getting the exception because you are trying to access an Account object in your array but you have not actually created any Account objects. The line [code]database=new Account[MAXACC];[/code] creates an array of Account references, but those are still null until you assign an element an object like so [code]database[0] = …

Actually, the part in bold was not necessarily what I had in mind - but it does fix the error. You really don't need to create Account objects until they are requested, as in createNew(). You would need to take care to make null checks before performing any operations on an array reference of course. It would actually be easier if you used an …

Ok, I missed one other thing on my first glance on the code. Your initialization block is not getting called because it is not static and you are using the class in a static manner. Add the 'static' keyword before your initialization block and it will work fine:[code] // initialisation block static { acc_logged_in=-1; …

You will need to use a nested for loop if you want to print fixed number of characters horizontally also. Following is how you loop would look like (note it is just for an illustration, you may have to modify it further to get what you exactly want) :- [code=java] final int noOfCharsPerLine = 10; for (int i = 128; i < 256; i++){ for…

good, it should give that error. You've just proven that your compiler works. It can't find the class because the class isn't in the same package and you failed to import it. You stupidly didn't put the class in a package so it's of course quite impossible to import it, but that's something you can easily rectify.
