Write a java program in jgrasp that creates a 2d integer array of 5 rows and 20 columns, fills it with increasing integer values ranging from 0 to 59 and then prints the array

As per the question we need to make 5 rowa and 2o columns, in this we have total element 100 so range should be 0 to 99, but we are suggested to keep range 0 to 59, so i have kept the elementns in the range, but if it was a typo in the question for range you do not need to reset the k with zero.

Explanation:

//create a new class  TestArray

public class TestArray {

//define main method

public static void main(String[] args) {

 //declare a 2D array of given size i.e. 5 rows and 20 columns

 int arr[][] = new int[5][20];

 //declare an integer variable k and initialize it with zero, this will used to initialize the array from 0 to 99

 int k = 0;

 //for loop for rows

 for (int i = 0; i < 5; i++) {

 //for loop for columns

 for (int j = 0; j < 20; j++) {

   //initialize arr with the current value of k

   arr[i][j] = k;

   //once k is 59 set it zero again as we are not going beyond 59

   if(k == 59)

   k = 0;

   //increment value of k with 1

   k++;

 }

 }

 //print the element from the array one by one

 //for loop for rows

 for (int i = 0; i < 5; i++) {

 //for loop for columns

 for (int j = 0; j < 20; j++) {

   //print the current element of array and an space with it

   System.out.print(arr[i][j]+" ");

 }

 // move the cursor to new line

 System.out.println();

 }

}

}

the answer is c. data centers
