Today i am going to share my first java project with you guys, I started learning java about 8-10 weeks back and my first project was to make a scientific calculator. It has all the basic function and most scientific functions. It has the ability to switch between basic and scientific mode and also to switch between degrees and radians. If you guys want to try it out, here is the link to download the jar file -
Windows - CalculatorWindows
Mac - CalculatorMac (Sorry for the graphics on mac, Netbeans automatically uses these, they don't look as clean or crisp as windows)
(Only difference between Windows and Mac are the graphics, same features in both of them)
If you have any questions just post them in the comments section and i'll try and get back to you.
