Final Grade Calculator (calculates necessary score for the final):
- First takes in boolean of whether final is in a seperate category or tests cateogry
- If final is in seperate category
- take in current grade
- take in % of grade that is final
- take in the desired grade
- output % score needed on the final
- If final is in a "tests" category
- take in current grade
- take in % of grade that is tests category
- take in current % in tests category
- take in CURRENT amount of points in tests category (here integer can be used i suppose)
- take in amount of points that the final is (here integer can be used i suppose)
- take in the desired grade
- output # of points needed on the final All of these should be taken using user input (Scanner). Example Input: false 20 93.0 90.0 Example Output (would be correct if contains a 78): Is the final in the tests category? What is your current grade? How much percent of your grade is the final? What is your desired grade? You need a 78.0 on the test
