Create a program where you have to design your own Java console application about any valid problem that your application must solve. Your solution can include solving a business problem, a new idea or even 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. Use Advanced arrays & Introduction to inheritance

Create a GUI interface

1. When the program starts the user needs to be asked if they want to make a new entry or to

view a previous entry

2. If the user wants to make a new entry, the first question will be how many meters they

travelled (this will then need to be converted into kilometers)

3. The second question will give the user 3 options to choose from, and each option will have a

value. The options are as follows:

a. Hatchback = 3

b. SUV = 3.5

c. Sports car = 4.

When the user has selected an option that options value needs to be multiplied by the

distance they travelled in kilometers

4. The third question will allow the user to enter a description, of where they travel to and why

did they travel there.

5. All the information above needs to then be saved into a JSON file

6. If the user says he want to view a previous entry the JSON file needs to be loaded and

displayed.

7. You need to make use of error handling to ensure that the user only types in items that are

asked and not anything else

Write a python program that will take the quiz, mid, lab and final marks from the user and calculate the grade.

Total_marks = quiz+mid+lab+final

Total_marksGradeFrom 90 to 100(inclusive)"Grade: A"From 80 to 89(inclusive)"Grade: B"From 70 to 79(inclusive)"Grade: C"From 60 to 69(inclusive)"Grade: D"From 50 to 59(inclusive)"Grade: F"Less than 0 or more than 100 (exclusive)"Invalid Input"

Sample Input:

Quiz marks = 18

Mid marks = 30

Lab marks = 20

Final marks = 26

Sample Output:

Grade: A
