Question

1. The game Battleship is played on a grid board. Each opponent has multiple ships that are placed on the grid where the other opponent cannot see them. In order to attack, each player takes turns calling out coordinates on a grid. If the attacker calls out a coordinate that hits their opponent's ship, they must call out, "Hit." You are going to be developing a computer program to mimic this game. Use the Gridlayout that is six columns by six rows. Randomly make one row or one column all ones. The other cells will be 0. The user should not see these values. When a user selects a cell, expose the value. The game is over when the user correctly selects all of the cells with 1s in them. Call this class Battleship.java.
2. Tic-Tac-Toe is a game played on a grid that contains three rows by three columns. When a player gets three of their values across, down, or diagonal, they have won the game. Create a java version of this game by using Gridlayout that is constructed with three columns and three rows. The user will go first. When the user selects a cell, put an "x" in that cell. Next, randomly add a 0 to a cell to mock the computer playing. Call this class TicTacToe.java.
3. Place the following files in a folder (Battleship.java and TicTacToe.java), and label it "Lesson 7." Zip the folder as described in the Syllabus.
