Create a Java program that prompts the user to input the scores of 10 students, divided into 2 groups of 5 students each. You should store these scores in a two-dimensional array and display the arithmetic mean (average) for each group of students.
4 5 3 6 3 7 4 8 3 5 6 2 6 7 4 6 7 4 2 3
The average for group 1 is 4.8 The average for group 2 is 4.7
import java.util.Scanner; public class TwoDimensionalArray { public static void main(String[] args) { int studentsPerGroup = 5; float[][] scores = new float[2][studentsPerGroup]; float totalGroup1 = 0.0f, totalGroup2 = 0.0f; Scanner input = new Scanner(System.in); // Get scores for (int i = 0; i < 2; i++) { for (int j = 0; j < studentsPerGroup; j++) { scores[i][j] = input.nextFloat(); } } // Calculate the arithmetic mean for group 1 for (int i = 0; i < studentsPerGroup; i++) { totalGroup1 += scores[0][i]; } System.out.println("The average for group 1 is " + totalGroup1 / studentsPerGroup); // Calculate the arithmetic mean for group 2 for (int i = 0; i < studentsPerGroup; i++) { totalGroup2 += scores[1][i]; } System.out.println("The average for group 2 is " + totalGroup2 / studentsPerGroup); } }
