How to Make a Game in Java?
Follow these instructions to learn “how to make a game in Java.”
Start by learning Java Core
- Study the OOP fundamentals. What are inheritance, encapsulation, polymorphism, and object? Inner classes, interfaces, and classes.
- Java Collection Framework includes several classes and interfaces that can represent a collection of objects as a single entity.
- Learn how to use the List, Map, and Set implementations of the Java Collections and Map interfaces to access data structures.
- The Java Exception mechanism makes it easier to find bugs in programs. Additionally, all exception classes are Java.lang subtypes.Special case class.
- Java uses streams to carry out input and output actions. Data appears to be flowing continuously in a stream.
- Java multithreading is a challenging subject. Furthermore, even the most minor task could be difficult for a novice using the Thread API. However, it is crucial and enjoyable to use once you learn how.
- And other fundamentals of theory.
Master the fundamentals of Android Development
The official Android website is a fantastic source of information for developers. Furthermore, you can follow the tutorial to create your first Android app. Additionally, learning about game elements like sound, graphics, and physics would be beneficial if you are familiar with Java Core.
Moreover, we suggest enrolling in CodeGym‘s Android app development for beginners course if you prefer to study with a tutor. Additionally, you can start at the very beginning and explore the fundamentals of programming before moving on to mastering Android development. Alternatively, if you are already familiar with some programming languages, you can start learning Android immediately. Course content includes:
- twice-weekly mentored online lectures;
- support in a Slack chat from CodeGym and your mentor
- the development of four complete Android applications;
- debugging in real-time;
- extensive final project;
- completion diploma for the course.
Study libGDX
A framework for creating cross-platform games is called libGDX. As a result, you can create a single code that runs on Windows, Linux, macOS, Android, iOS, and the Web. Moreover, it’s written in Java and offers a tonne of great functionality, such as sound, asset handling, storage, drawing APIs, and so on) to make game development a lot simpler.
Furthermore, there is enough documentation to get you going. Additionally, LWJGL supports cross-platform APIs for making music and sound effects. Moreover, the open standard for cross-platform, parallel programming is OpenAL and OpenCL.
Now you know all the steps for “how to make a game in Java.”

Java 2d gaming (Flappy Bird Redux)
Here is the starting code for making a game in Java.
Import java.awt.Dimension;
import java.awt.Image;
import java.awt.Toolkit;
import javax.swing.*;
public class TopClass {
//global constant variables
private static final int SCREEN_WIDTH = (int) Toolkit.getDefaultToolkit().getScreenSize().getWidth();
private static final int SCREEN_HEIGHT = (int) Toolkit.getDefaultToolkit().getScreenSize().getHeight();
//global variables
//global swing objects
private JFrame f = new JFrame("Flappy Bird Redux");
//other global objects
private static TopClass tc = new TopClass();
/**
* Default constructor
*/
public TopClass() {
}
/**
* Main executable method invoked when running .jar file
* @param args
*/
public static void main(String[] args) {
//build the GUI on a new thread
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
tc.buildFrame();
//create a new thread to keep the GUI responsive while the game runs
Thread t = new Thread() {
public void run() {
//here, we will call a function to start the game
}
};
t.start();
}
});
}
/**
* Method to construct the JFrame and add the program content
*/
private void buildFrame() {
Image icon = Toolkit.getDefaultToolkit().getImage(this.getClass().getResource("resources/blue_bird.png"));
f.setContentPane(createContentPane()); //adds the main content to the frame
f.setResizable(true); //true, but the game will not function unless maximized!
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setAlwaysOnTop(false);
f.setVisible(true);
f.setMinimumSize(new Dimension(SCREEN_WIDTH*1/4, SCREEN_HEIGHT*1/4)); //set to prevent collapse to tiny window upon resizing
f.setExtendedState(JFrame.MAXIMIZED_BOTH); //maximize the JFrame
f.setIconImage(icon); //set the icon
}
private JPanel createContentPane() {
topPanel = new JPanel(); //top-most JPanel in layout hierarchy
return topPanel; //return a blank panel
}
}
Don’t stop learning; keep practicing
Furthermore, you must continually develop your talents as technologies advance, people’s interests change, and they grow more demanding. Additionally, keep in mind to divide your time between reading up on subjects and performing practical activities, giving practice more time. Moreover, that’s how you will learn to make a game with Java.
What to consider when studying Java?
Furthermore, do you recall watching babies struggle to walk before repeatedly getting back up? Moreover, programming follows a similar pattern in that it is valuable. Again, making applications is everything! You can only be confident that you understand an idea if you put it into practice.
Furthermore, if you are familiar with its fundamental concepts, you can only go on to the next level and experiment with Java’s more complicated features.
git and GitHub
Additionally, git is the most popular version-control tool for keeping track of changes made to computer files and organizing collaborative work on those files among numerous individuals.
Furthermore, the most extensive website for hosting and collaboratively developing IT projects, GitHub, should be known to every professional. Additionally, you may practice creating games once you’ve gotten the hang of developing Android apps. Furthermore, numerous written and video guides on creating easy games are available online.
