Question

Write a program that calculates your provisional final grade in Java!

Read a file that contains each grade

Each type of grade is denoted by a header and every grade are on separate lines. See the test files (http://bit.ly/1TmbUxX) for how it should be formatted.

Lab assignment average is 20% of your grade

Homework assignment average is 30% of your grade

Drop the lowest grade

Lab Test 1 is 10% of your grade

Lab Test 2 is 10% of your grade

Exam 1 is 10% of your grade

Exam 2 is 10% of your grade

Final Exam is 10% of your final grade

Extra Credits are worth 2% a piece

This adds up to 110% but the final grade is taken out of 100

A is 90-100

B+ is 85-89

B is 80-84

C+ is 75-79

C is 70-74

D+ is 65-69

D is 60-64

F is anything below 60

Round up to the nearest whole number

HINT: Math.ceil

Print out the provisional final grade at the end.

Example Dialog:

Your lab average is 92

Your homework average is 90.0

Your first exam is 65.0

Your first lab exam is 100.0

Your second exam is 65.0

Your second lab exam is 100.0

Your extra work total is 4.0 points

Your final is 80.0

Your raw total is 91.0

Your final grade is A
