AP Computer Science 2-D Array Programming Assignment

Write a program that calculates the test average for each student and the average for each test.

TestScores File

Create a class TestScores that has a calcStudentAverage(int row), calcTestAverage( ), and calcCurvedAverage( ). There should be a default constructor and a constructor that has a 2-D array of test scores as a parameter. The class should contain one instance field, the array of test scores.

calcCurvedAverage( ) If every test score increases from the last test score for the entire quarter, the student earns the highest/last test score for his/her test average for the quarter. Otherwise, the average (mean) is calculated by calling the calcStudentAverage(int row).

The calcStudentAverage(int row) method will return the average of one students test scores.

The calcCurvedAverage( ) method will return a 1D array of student test averages.

The calcTestAverage( ) method returns a 1D array of test averages.

TestScoresTester File

Your program will create and assign the 2-D array of test scores in the test/client file called TestScoresTester. Each row represents the test scores for a single student and each column represents test scores for the same test. Pass the array of test scores to the class through the constructor. Call the calcCurvedAverage( ) and calcTestAverage( ) methods in the test file. Use the returned values and the original array to create the output.

Examples of 2-D Arrays: int[ ][ ] tests = { {80,90,100}, {88, 98, 87}, {78, 89, 92}};

int[ ][ ] tests = { {92, 84}, {79, 85}, {85, 90} ..};

Example of Output

Test Averages

Test 1 Test 2 Test 3 Average

Student #1 80 70 90 80

Student #2 78 88 98 98

Student #3 75 85 80 80

Test Average 77 81 89

Your program should output the test average for each student and the average for each test. The output should be organized in a format that is easy to interpret.
