Challenge: Creating a simple calculator application

- So now it's time for a simple challenge,…to create a simple console application…that takes user input, translates strings…to numerical values, executes a mathematical operation,…and returns the result to the console.…I'm working in the project SimpleCalc.…Now, don't open it quite yet, but I'll show you…what the finished application looks like when I run it.…I'll run the application, and my run window opens…at the bottom of the screen.…I see a prompt, enter a numeric value.…

I'll type in a value of 15, and I'm prompted…for a second value.…This time I'll enter a fractional value, 16.5.…And when I press enter, I get back the answer…as 31.5, and the application finishes.…So, that's the application you should create.…I encourage you to create the project from scratch.…Create a brand new Java project,…and put all the code into the main method of the main class.…Using the scanner class, get some input from the user,…using the helper classes for the primitive data types,…parse the strings that you get into primitive numbers,…
