How To Create Snake Game In Java? A step-by-step Guide with Source Code

The Code Given Below Is For The Connection Module

package cls;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

import javax.swing.JOptionPane;

/**

 * @author bagong

 */

public class ClassDB {

    // static final int math.random

    private static Connection koneksi;

    //  public static void main string args    

    public static Connection getkoneksi() {

        if (koneksi == null) {

            try {

                String url = new String();

                String user = new String();

                String password = new String();

                url = "jdbc:mysql://localhost:3306/snake";

                user = "root";

                password = "";

                DriverManager.registerDriver(new com.mysql.jdbc.Driver());

                koneksi = DriverManager.getConnection(url, user, password);

                // JOptionPane.showMessageDialog(null,"Koneksi Berhasil");

            } catch (SQLException t) {

                JOptionPane.showMessageDialog(null, "Error membuat koneksi");

            }

        }

        return koneksi;

    }

}

This module serves as a bridge between Java NetBeans and the MySQL database. 

The Code Given Below Is For The Player Name Module

private void nama() {

    // We stored the public class snake in the nama variable    

    Nama = JOptionPane.showInputDialog(this, "Please Input Your Name:");

    if (Nama == null) {

        System.exit(0);

    } else {

        if (Nama.equals("")) {

            JOptionPane.showMessageDialog(this, "Name Already Exist!");

            nama();

        } else {

            try {

                Connection c = ClassDB.getkoneksi();

                Statement st = (Statement) c.createStatement();

                String ceknama = "Select * from score where nama = '" + Nama.toString() + "'";

                ResultSet r = st.executeQuery(ceknama);

                if (r.next()) {

                    return;

                } else {

                    try {

                        st.executeUpdate("Insert into score(nama) values('" + Nama.toString() + "')");

                    } catch (Exception e) {

                        System.out.println(e);

                    }

                }



            } catch (Exception e) {

                System.out.println(e);

            }

        }

    }

}

This module is the module for entering the name of the player to start the game and the positions of the snake.

The Code Given Below Is For Updating the Score Module

private void updatescore() {

    try {

        Connection c = ClassDB.getkoneksi();

        Statement s = (Statement) c.createStatement();

        String cektinggi = "Select * from score where nama = '" + Nama.toString() + "'";

        ResultSet r = s.executeQuery(cektinggi);

        if (r.next()) {

            scoretinggi = Integer.parseInt(r.getString("score"));

            if (scorenya <= scoretinggi) {

                return;

            } else {

                String sqel = "UPDATE score Set score ='" + scorenya + "' where nama = '" + Nama.toString() + "'";

                s.executeUpdate(sqel);

            }


        }

    } catch (Exception e) {

        System.out.println(e);

    }

}

In this module, the score of the game is updated using void keypresses.

The Code Given Below Is For The Game Over Module

private void gameOver(Graphics g) {

    updatescore();

    if (scorenya <= highscore) {

        String msg = "Your Score: = " + scorenya;

        Font small = new Font("Helvetica", Font.BOLD, 14);

        FontMetrics metr = getFontMetrics(small);



        g.setColor(Color.white);

        g.setFont(small);

        g.drawString(msg, (Lebar - metr.stringWidth(msg)) / 2, Tinggi / 2);



    } else {

        String msgg = "Congratulation High Score = " + scorenya;

        Font small = new Font("Helvetica", Font.BOLD, 14);

        FontMetrics metr = getFontMetrics(small);



        g.setColor(Color.blue);

        g.setFont(small);

        g.drawString(msgg, (Lebar - metr.stringWidth(msgg)) / 2, Tinggi / 2);

    }


}

In this module, which is the module for game over function void move.
