Scanner keyboard = new Scanner(System.in);

How come the print statement prints false if the user enters "+"?
New to android studio and Java development. I'm exploring some APK source code I found online and it does not have any gradle build files. I am using Android studio and wondering how to generate these files. The two options I am seeing seem to be (1) Create myself from scratch, (2) Export the project from Eclipse building these files in the export process. Any thoughts?

In case the title was confusing, here is what I mean. When I use the code Math.tan(45); to return a number, I can't use Math.atan(Math.tan(45)); to return 45. I can't just make it simply return 45, because I want it to be dynamic.
How would I return the degree measure of a tangent, sine, or cosine?
Im using cognito developer authentication provider as my access control for my mobile app. Problem is in mobile apps, once the user logs in he/she doesnt have to login again.

The hard drive on my laptop just crashed and I lost all the source code for an app that I have been working on for the past two months. All I have is the APK file that is stored in my email from when I sent it to a friend.
Is there any way to extract my source code from this APK file?
