Java – what should I use to display game graphics?

I have a game system, but I don't know how to display it I'm making a vertical shooter game. I've written methods for all classes that control enemies and players, but I don't know how to effectively display the game I was thinking of a canvas that redraws every frame, but is this really the most effective way?

Important details:

>Ideal frame rate: 25FPS > this is a 2D Game > there are 25 to 100 objects on the screen at any time, and all objects are moving > all displayed objects are images in PNG format > the window is 640px × 480px > now all images are loaded as bufferedimage, although I can easily change it

I need a coordinate plane This is the only basic part that cannot be changed without completely refactoring my code

The most important thing is the way I set all the contents. Every frame of all objects moves and interacts in the coordinate plane I designed (dealing with collision detection and movement, without graphic components). Then everything should be drawn on the screen. Just track all moving objects through ArrayLists and draw them one by one

Solution

If swing is acceptable, JPanel is double buffered by default, and the cycle is 40 ms javax swing. Timer will provide you with ~ 25 Hz updates This example shows the basic method, and this example shows many moving images

It is not uncommon for models and views to use different coordinates; All you need is the ability to map one system to another In this game, views rely on four methods to map blocks to pixels and vice versa For map blocks, the same approach is outlined here
