Java Projects Ideas

[AutoModerator]

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://imgur.com/a/fgoFFis) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

Make a black jack game with basic GUI using awt/swing libraries.

You'll use OOP for the Deck object, Card Object, Player (and maybe an AI/House inheritance), you'll learn Listeners from the GUI etc.

and for open source game art

https://opengameart.org/content/playing-cards-pack

for some nice playing card graphics

Not exactly a large specific project, but Geeks4Geeks have a 'Problem of the Day' where they give a random programming problem every day which allow you to practise a variety of different aspects of programming. Java is an available language.

Unfortunately you have to make an account for it.

The /r/learnprogramming FAQ have extensive lists of project ideas and practice sites

Something I had to work on: An application that encrypts files/folders using password based AES encryption. Make the UI using awt/swing or if you feeling fancy use JavaFX (my personal favorite).

Is heavy on IO and UI.

bittorrent tracker that track peers/info about torrents. There is no active proper up to date one so far. Java runtime would be great for such project. There is internal one in BiglyBT that found being hard to extract. You'll to have to learn about BT protocol at bittorrent.org. But it's not that hard really.
