Write a 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: (7, 6, 2}, {0, 8, 3), (5, 5, 1}; array = rowl = 0; row2 = 2; OUTPUT: nothing is returned, but the array now references the following data in memory (5, 5, 1}, (0, 8, 3), {7, 6, 2); array =

1. Write a program that calls a method that takes a character array as a parameter (you can initialize an array in the main method) and returns the number of vowels in the array.

A method named getUserStringsAndPopulate Array(). This method should keep prompting the user to enter as many strings as the user wants. The user should be able to stop entering strings by entering EXIT. This method should take the strings entered by the user and populate a one-dimensional array of strings with the user input. The string EXIT should NOT be added to the array because it is a special flag that will tell the method to stop prompting the user to enter more strings. This method should return the one-dimensional array of strings populated with user input and should not accept any arguments. 2.b) A method named searchArray() that would accept a one-dimensional array of strings and search the array for the string Winter. The search logic should NOT be case sensitive. If a match is found, this method should print the string in the array followed by a message like "  --- Found a match!". Otherwise, the method should not print anything. This method should NOT return anything.…

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.
