PS: Please answer number 1 and 2 as they are all linked altogether with the subparts perfectly. Write a Java Program and introduce an intentional error in it. 1. Your program must include the following: a. Loops and Arrays (You can use an old, submitted program) 2. Once you have created your program, debug the application in eclipse and fix the error. a. Ensure that you take at least 3 screenshots of the debugging process and provide a brief explanation of the step. b. Ensure you use breakpoints and submit a snapshot labelling it. c. Submit all steps.

You have to design your own Java console application about any valid problem that your application must solve. Your solution can include solving a game. Your application must make use of concepts such as arrays, loops, inheritance, constructors and information hiding. Output must be shown in the form of a report using the console. In your solution, make use of as many concepts, and components dealt with in this course, butpay special attention to the following:• Advanced arrays.• inheritance. (all in java form)
