Write a JAVA method that takes three inputs. The first input is a 2d array of integers, the second and third inputs are integers to be used to index rows of the array. Fill in the code in the method so that it swaps the values in the indexed rows. Example method header: public static void rowSwap(int[][] array, int row1, int row2) Example input and output: INPUT: array = {7, 6, 2},          {0, 8, 3},          {5, 5, 1}; row1 = 0; row2 = 2; OUTPUT: nothing is returned, but the array now references the following data in memory array = {5, 5, 1},          {0, 8, 3},          {7, 6, 2};

The programming language used is Java

Write a Java method (do not write a class, only the method) with the following signature: Return type: void Parameters: 2D integer array Name: printDiagonal Implement the method code that will print out the values of the 2D array along the Diagonal from left to right. For example, if the array had the following values: 56    78    98 21    33    55 98    44    11        The method should print to the console:   56,33,11 The above 2D array example is only given for you to understand the problem Do not hard code the values in your solution or assume the array is the same as the given data. Your method should work for all 2D integer arrays.

THIS IS DONE IN JAVA

In JAVA Write the method below: Given a two-dimensional array containing integers, create a method called "matrixOperations"  The method should do the following:1. Print out all the numbers in the array row by row (add empty line at the end of the row)2. For each row, print out the length of the row (each row is an array, remember)
