Create a JAVA simply programs that manages scores following a 2-dimensional array, students can be identified with rows, scores indefity with the columns. Ask user to input number of science students for the #of tests (size of 2-D array. Array must get populated with user input (numbers for scores ranging from 0-100). Note that >= 60 equals a passing grade. Next, 2 methods 1. Calculate # of tests passed by each student 2.Calculate # of students passed for each test Note that the Method will accept the two-D array as 1 argument & specific student # (for(a)) or a specific test # (for(b)) as next argument. Methods return the counts if correct. Next you will Call the above methods (from main) by passing 2-D array with the scores, for each student (for(a)) and each test (for (b)). Print all counts.

Question
Create a JAVA simply programs that manages scores following a 2-dimensional array, students can be identified with rows, scores indefity with the columns. Ask user to input number of science students for the #of tests (size of 2-D array. Array must get populated with user input (numbers for scores ranging from 0-100). Note that >= 60 equals a passing grade.
Next, 2 methods
1. Calculate # of tests passed by each student
2.Calculate # of students passed for each test
Note that the Method will accept the two-D array as 1 argument & specific student # (for(a)) or a specific test # (for(b)) as next argument. Methods return the counts if correct.
Next you will Call the above methods (from main) by passing 2-D array with the scores, for each student (for(a)) and each test (for (b)). Print all counts.
Expert Solution
Step 1
I have implemented the requirements as per specification. The code for the above is:
import java.util.Scanner;
public class StudentScore {
public static int countTests(int[][] studentScores, int student) {
int count = 0;
for(int i = 0; i < studentScores[student].length; i++) {
if(studentScores[student][i] >= 60)
count++;
}
return count;
}
public static int countStudents(int[][] studentScores, int test) {
int count = 0;
for(int i = 0; i < studentScores.length; i++) {
if(studentScores[i][test] >= 60)
count++;
}
return count;
}
public static void main(String[] args) {
int noStudents, noTests, countStudent, countTest;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the number of students: ");
noStudents = Integer.parseInt(sc.nextLine());
System.out.println("Enter the number of tests: ");
noTests = Integer.parseInt(sc.nextLine());
int[][] studentScores = new int[noStudents][noTests];
for(int i = 0; i < noStudents; i++) {
System.out.println("Test Scores of student #" + (i + 1) + ": ");
for(int j = 0; j < noTests; j++)
studentScores[i][j] = sc.nextInt();
sc.nextLine();
}
System.out.println("=======================================================");
for(int i = 0; i < noStudents; i++) {
countTest = countTests(studentScores, i);
System.out.println("Student #" + (i + 1) + " passed " + countTest + " tests.");
}
System.out.println("=======================================================");
for(int i = 0; i < noTests; i++) {
countStudent = countStudents(studentScores, i);
System.out.println("Test #" + (i + 1) + " passed by" + countStudent + " students.");
}
System.out.println("=======================================================");
sc.close();
}
}
