Question

Write a java code that Declares and initialize a two-dimensional int array named grades. It should have 10 rows and 6 columns where it stores the values and then calculates the average of all the elements in the grades array that you have declared

Answer 1

import java.util.Scanner;
public class MyClass {
public static void main(String args[]) {
int[][] grades = new int[10][6];
int total=0;
double avg;

Scanner input=new Scanner(System.in);
System.out.println("Enter the grades: ");
for(int i=0;i<10;i++)
{
for(int j=0;j<6;j++)
{
grades[i][j]=input.nextInt();
total=total+grades[i][j];
}
}

avg=total/60;

System.out.println("Average of Grades is : "+avg);
}
}
