Yes, I made a calculator. It sucks, but I'm proud of it. 

Let me know what you think of it!

Thats actually pretty nice   Are you planning to add any other features or do you plan to move onto other projects?

Yeah, I'll probably add some other features to it like decimals and negative numbers- maybe exponents. I'm probably not going to spend a whole lot more time on it, though.

Yes, but you can only get a negative number by subtracting from a positive one. What I meant was that I was going to add in a negative symbol so that you can multiply and divide by negatives.

mhmm
when I type numbers, then + then try typing another number, it continues adding digits

Hmm its nice. I don't get the thing DJ is getting though. However, it doesn't auto-clear if it is supposed to (like if you do an equation then try entering stuff without hitting clear it just adds the number to the end or something). Also, I would reverse how the ^x√y works, as I would put what root you are doing and then the number that is being "rooted." Just my opinion. It's very nice though.

You should add symbolic support. With Java's built-in string handling it shouldn't be that hard.
Also, maybe display the expression as you type it, instead of just the numbers?

Yeah, I could probably put that in. It's still a work in progress, and there's still some stuff that I want to add to it.

Nice, do you plan to add some features not present in other windows calculators or is it mostly for learning experience?
