College GPA Calculator

Objective: Implement a Java program that simulates a college GPA calculator. This program will

prompt the user to enter three grades to calculate. The program will convert these numeric grades

into letter grades using a predefined grading scale and calculate the GPA accordingly.

Define $12$ final floating$-$point constant variables representing the numeric values for each letter

grade as follows:

$A=4$

$A-=3\mathrm{.}7$

$B+=3\mathrm{.}3$

$B=3$

$B-=2\mathrm{.}7$

$C+=2\mathrm{.}3$

$C=2$

$C-=1\mathrm{.}7$

$D+=1\mathrm{.}3$

$D=1$

$D-=0\mathrm{.}7$

$F=0$

Grading Scale: Use the grading scale from the course syllabus to determine the letter grade based

on the numeric input:

Implementation Details

Use separate variables for each grade.

For each grade, ask the user to input the numeric value.

Use decision structures $($e$.$g$.,$ if$-$else or switch statements$)$ to determine the corresponding letter

grade based on the numeric input.

Compute the numeric average of all grades entered.

Display the final GPA as both a numeric average and a letter grade, along with the equivalent

GPA value.

Use concepts covered in chpters $1-3$ only.

Note: Be sure to use the program rubric.
