Two players, X and O, alternate in placing their respective marks in the cells of this board, starting with player X. If either player succeeds in getting three of his or her marks in a row, column, or diagonal, then that player wins. In this homework, you should use the OOP concepts to implement the tic-tac-toe gameWhen one class includes objects that belong to another class, this is known as a whole-part relationship or composition. The conclusion is that a has-a connection exists. Consider the following lengthy assertion: getHireDate(), getYear(), and Outputsales.getHighestPaidEmployee() are some useful functions ().

The method isSolvable() willbe called in the main, if it returns true display the calculated values for x and y by calling getX()and getY(). If the call to isSolvable() returns false, display a message that “the equation has nosolution”.Write a test Java program that prompts the user to enter a, b, c, d, e, and f and displays the result. After the valuesfor a through f are entered, create a LinearEquation object. Check to seeIf ad - bc is 0, report that “The equation has no solution”, otherwise print out the values for x and y.A constructor that accepts arguments is known as a(n) __________.
