Java is widely used but there aren't many projects to practice with

I previously learned Python, the language has a lot of libraries and projects, from games to applications to websites, etc. But I think there aren't many for Java, most of what I see are just OOP projects (management projects). I'm a beginner and I don't know a lot about it, but I rarely see Java GUI frameworks or game frameworks, it's all backend frameworks for companies, I feel like it's not as diverse as other languages.
