Sorting algorithms java Create four methods named insertionSort(), bubblesort(), mergesort() and quicksort(). Implement the sorting algorithms in the corresponding methods. In the main method, create four arrays a, b, c, d and initialize them with the same values. Pass these four arrays in four different functions. Create four instance variables named insertionSwap, bubbleSwap, countMerge, and countQuickSort and initialize them to 0. In methods insertionSort(), bubblesort() and quicksort(), increment the variables insertionSwap, bubbleSwap, and countQuickSort respectively by one whenever they call the method swap(). In method mergesort(), increment the variable countMerge by one to count the swaps. Use method swap() to swap the values.

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
