About Java HTTP Requests
Java's HttpURLConnection is part of the standard library and provides a straightforward way to make HTTP requests. While more verbose than some alternatives, it's dependency-free and available in all Java environments. For modern Java applications (11+), the HttpClient API offers a more fluent interface with async support.
Key Features
- Part of the Java standard library
- No external dependencies required
- Support for all HTTP methods
- Input/Output stream-based for large payloads
- Proxy and authentication support
- SSL/TLS support built-in
- Available in all Java versions
Frequently Asked Questions
How do I convert a curl command to Java?
Paste your curl command in the input box and click "Convert". The tool generates Java code using HttpURLConnection with proper exception handling.
Should I use HttpURLConnection or HttpClient?
HttpURLConnection works in all Java versions. If you're using Java 11+, consider the newer HttpClient API for a more modern, fluent interface with async support.
How do I parse JSON responses in Java?
Use a JSON library like Jackson or Gson. For example, with Gson: new Gson().fromJson(response, YourClass.class). Or use the built-in org.json package.
Does the generated code handle errors properly?
Yes! The code wraps operations in try-catch blocks and handles IOException. It also properly closes resources using try-with-resources for streams.
Can I use OkHttp instead?
OkHttp is a popular alternative that provides a simpler API and additional features like connection pooling and automatic retries. This tool generates standard library code for maximum compatibility.
