3.1 Using an IDE, develop a grade-calculator for 12th grade (Tawjihi) school students based on the new regulations, where a student shall be able to enter his/her grades per semester every time he/she runs the application, then the system will calculate the semester`s average and the total average for that students. This application should be developed using Java programming language and the IDE of your choice. You can either decide whether to utilize GUI (Graphical User Interface) with Java using Swing framework, or implement it using a CLI (command line interface) (Program).

3.2 Evaluate the use of an IDE for development of applications contrasted with not using an IDE. (Report).

3.3 Explain the debugging process you followed in writing your programs, and explain the debugging facilities available in the IDE. Moreover, evaluate how the debugging process helped you to develop more secure, robust applications. Finally, outline the coding standard you have used in your code; and critically evaluate why it is was necessary in your work specifically and in team works generally (Report).
