Is it difficult to create a game in pure Java?

Question

Java

Good day. The question arose, is it difficult to write games in pure Java without using third-party libraries? And what are the challenges you might face?
Didn't find an answer on google. Thanks in advance!

Answer 1

See what games.
Text quests - already running. The MMO server is real. But TOTALLY without libraries and with normal graphics - it's complicated.
And so, if at least with openGL - look at minecraft ;-)

Answer 2

JavaFX 8 has support for simple 3D graphics. So if the requirements are not high, then you can do without links with OpenGL. Well, if you need only 2D - then you can not doubt it at all.

Answer 3

If you write yourself opengl/etc - yes.

Answer 4

Face the lack of game engines.
And you have to write it yourself.
And this is at least tens of thousands of dollars of extra costs.

Answer 5

Well, there is an article on Habré about writing a software renderer.
And so is libGDX. I would not say that a complex structure

Answer 6

Of course it is possible.
import javax.imageio.ImageIO;
import javax.swing.*;
import java.awt.*;
import java.awt.image.BufferedImage;
and forward.
But why? If the goal is to gain experience - then ok.
If the goal is to get the game, it's better to take the engine.
