Understanding Java Game Engines

Java game engines are software frameworks that enable you to develop games quickly using Java. A range of tools and features are available to assist you in game development, so you don't have to write every bit of code yourself.

These engines can be very helpful because they include physics engines, audio support, and scripting languages.

Games and engines fall into two categories:

a. 2D game engines: Suitable for creating games that don't require complex graphics, such as puzzle games or side-scrolling platformers.

b. 3D game engines: More suited for creating games that require rich graphics, such as first-person shooters or racing games.
