    Do Conditions 1 and 2 give the same result? What tool or technique would you use to explain the result?

    not always. It depend on the value of cChoice. I assumed that you have jdk installed in you computer and you know how to create a simple program, so you can try it on yourself. just print their values giving a different value in your cChoice.


    System.out.println(!(cChoice == 'Q' || cChoice == 'q'))
    System.out.println(cChoice != 'Q' || cChoice != 'q')

    but first, declare a value for your cChoice. after compiling and running it, try another value for cChoice. Then after that, you can draw a conclusion of your own.
