2D arrays then solve the Write the following Java methods and test it in the main() method.

1. 1- Write a method printArray() to display the elements of a two-dimensional array of integers. The array is received as a parameter.
   public static void printArray(int [][] arr)
   Create a 2D array in the main method, call it array1, that is 10 rows and 5 columns and print it.

2. 2- Write a method fillArray() to initialize a two-dimensional array of integers to random values. The integer array is received as a parameter. The initialization values are generated randomly between a minimum and a maximum value.
   public static void fillArray(int [][] arr, int min, int max)

   Fill the array created in 1 (array1) with values between 10 and 100

3. 3- Write a method to determine if a two dimensional array is square or not. The method returns

   true if the number of rows is equal to the number of columns of the 2D array

   public static boolean isSquare(int [][] arr)

   Test your method with the created array array1.

   Create another array, call it array2, that has 5 rows and 5 columns, then fill it and test again.

4. 4- Write a method to determine and display the sum of all the values in the primary diagonal of a 2D

   integer array. The 2D integer array is received as a parameter to the method.

   public static int sumOfPrimary(int [][] arr)

   In the main method, get and display the sum of primary for array2.

5. 5- Write a method to determine and display the sum of all the values in the secondary diagonal of a

   2D integer array. The 2D integer array is received as a parameter to the method.

   public static int sumOfSecondary(int [][] arr)

   In the main method, get and display the sum of secondary for array2.

6. 6- Write a method to find the sum of each row in a 2-dimensional integer array. The return value is

   an array of integers.

   public static int[] sumofRows (int [][] arr)

   In the main method, get and display the sum of rows for both array1 and array2.

7. 7- Write a method to find the sum of each column in a 2-dimensional array. The return value is an

   array of integers.

   public static int[] sumOfCol(int [][] arr)

   In the main method, get and display the sum of columns for both array1 and array2.
