What are Java projects?
A Java project might be a small or large-scale programming project with a specific goal, such as automating routine chores, testing functionality, or developing applications for entertainment or education. Mobile games, interactive websites, and digital clocks are a few examples of Java projects.
What’s a coding portfolio?
A coding or GitHub portfolio is a collection of your work that showcases your programming skills, projects, and contributions to the coding community. It is a personal repository where potential employers, collaborators, and peers can view your code, understand your problem-solving approach, and see tangible examples of what you can build.
What can add to your portfolio:
- Personal projects: Projects you’ve built from scratch that demonstrate your creativity.
- Collaborative projects: Contributions to team projects or open-source repositories that show your ability to work with others.
- Documentation: Clear and concise documentation of your projects, explaining their purpose, features, and how to use them.
- Contributions to open-source projects: Showcase your coding and problem-solving skills. Here’s a blog to help you know more about open-source projects.
- Live demos: If applicable, links to live versions of your projects allow employers to interact with your work firsthand.
Now let’s take a look at a few projects that will help you build your coding portfolio.
