Design Tic Tac Toe Game In Java
Tic Tac Toe is a fun game to play .Before discussing tic tac toe java code , we should learn about the rules and regulations first.
This game has many variants , but the 3x3 variant is most popular .
This game is played between two players . Tic tac toe java program here is written for applet .The game has simple 3 rows and 3 columns , so make it a 3x3 grid.
Rules of the Game
The player whose turn is first has the choice to mark X or O to one of the nine squares , Here we choose X for first player .
Second player then mark its symbol O in the remaining 8 squares
The thumb of the rule is to make the three successive square grids of the same sign , it does not matter whether they are horizontal , vertical or diagonal , they just need to be three consecutive squares filled with same symbol X or O.
First player who is able to make three consecutive squares with same symbol WINS .
If players press the exit button then the frame closes .
If you are learning java, these are
the striking features of the tic tac toe java code:
- To make the lines thick we have used these two lines in our code
//get a graphics object
g2 = (Graphics2D)g;
/* Then setStroke method adds thickness to the line. Here you can pass the float value to the
method as an argument to control the thickness of the line */
g2.setStroke(new BasicStroke(10.0F));
//It will set the color of the line
g.setColor(new Color(77, 176, 230));
- When a user press the exit button the frame closes . It can be achieved by three ways in java
Here f is a frame object .
- To set the visibility of frame to false flag
f.setVisible(false);
- To use the dispose function
f.dispose();
3. Last one we all know
System.exit(0);
Pseudo code :
1. Board is drawn first using drawLine and drawOval methods .
2. Player X and Player O click the mouse on the empty grid of the board
3. Now Check at each click on the board
3.1 Is there any three vertical grids with same Mark (i.e X or O)
if true
Player with that mark Wins and display message Player 1/ 2 wins the match
3.2 Is there any three horizontal grids with same Mark (i.e X or O)
if true
Player with that mark Wins and display message Player 1/ 2 wins the match
3.3 All grids filled
if true
Display result is stalemate
4. Repeat step 2
5. If Clear then the board is again drawn and ready to play again .
6. If exit then the frame or window exits from the screen .
This is the second post for the Tic tac toe game . You can find first version here
Simple Tic tac toe game in java
In this post we have made numerous changes .
In this we added two functionality clear and exit button to the window . If the players press the clear button then the frame is redrawn to play the game again .
