Java136 Tasksbasic273Build a utility application (console or simple GUI using Swing/JavaFX) that converts between various units (e.g., length, weight, temperature, currency). Fetch currency exchange rates from a public API.
Java127 Tasksbasic72Intermediate
3 projectsDevelop a system to manage books in a library. Allow adding, searching, borrowing, and returning books. Store the library data persistently in files (e.g., CSV or JSON). Implement user roles (librarian, member).
Java94 Tasksintermediate3Create a tool that scrapes headlines and summaries from predefined news websites. Use a library like Jsoup for HTML parsing. Store the aggregated news locally and display it.
Java117 TasksintermediateBuild a command-line tool or a simple application that takes a Markdown file as input and converts it into an HTML file, supporting basic Markdown syntax like headings, lists, bold, italics, links, and code blocks.
Java82 Tasksintermediate2Advanced
3 projectsDevelop a web crawler that starts from a seed URL and recursively explores links found on pages up to a certain depth. Use multiple threads to fetch and parse pages concurrently, improving crawling speed. Ensure politeness by respecting robots.txt and adding delays.
Java95 Tasksadvanced2Build a mini ORM framework that can map Java objects to relational database tables. Implement basic functionalities like saving objects to the database, retrieving objects by ID, and performing simple queries based on object fields using Java Reflection.
Java113 Tasksadvanced1Build an application that fetches real-time (or near real-time) stock data from a financial API, displays it in a dashboard (could be console, Swing/JavaFX, or simple web UI using Spring Boot), and allows users to set alerts for specific price movements.
Java110 Tasksadvanced4Expert
2 projectsImplement a simple distributed task queue using a message broker like RabbitMQ or Redis Pub/Sub. Create producer components that enqueue tasks (e.g., image resizing, email sending requests) and consumer components (workers) running potentially on different machines that dequeue and process these tasks.
Java88 TasksexpertDevelop a simple Java agent using the Java Instrumentation API (`java.lang.instrument`) to perform basic profiling. For example, measure the execution time of specific methods by injecting bytecode at class loading time.
