How about you tell us what's wrong? What's happening? Are you getting an Exception? What did you expect to happen? What happened instead? Be specific.

When posting code, make sure you use the code tags. Check out other posts for examples of how to do that.

But here are the first couple of problems that pop out at me: you're trying to assign a String value to an int variable, then you're trying to print that variable outside of its scope.

So you want us to do your homework for you?

What happens when you put this into a main function and compile and run it?

hehe not like that.
I dont understand were to begin to solve that


what i get in is the error messeage: lastNumber cannot be resolved to a variable

i have been trying to change the code but nothing helps.

Okay, so what do you find when you google the error message?

I'll give you a hint: if you declare a variable inside a block (such as an if statement), you can't access it outside of that block. Just like you can't access a variable you declare in one method from another method.

Checking out the scope of variables is important, google for that, and it will save you hours of debugging later just to find out something was declared in the wrong spot. Also think ahead, and when declaring a variable decide whether and where you made need to use it again
