Online Java code formatting tool - one-click beautification, optimization code, improve readability!

This tool, based on prettier-plugin-java, is a professional online Java code formatter. It supports one-click beautification, smart indentation, and code standardization, helping developers quickly optimize code structure and improve readability and maintainability. No download required, it's completely free, and you can organize Java code online anytime, anywhere, making it ideal for learning, debugging, and team collaboration.

Inspiration

Java projects are often code-heavy, and inconsistent indentation and formatting can easily hinder readability and maintainability during team collaboration. This tool's design was inspired by the need for "quick and consistent style." Leveraging the Prettier plugin ecosystem, we've built a lightweight, ready-to-use online Java formatting platform, helping developers save on repetitive work and focus on business logic.

How to Use

1. Paste the Java code into the input area at the top of the page.

2. Click the "Format" button, and the tool will automatically optimize indentation, layout, and style.

3. Copy the result with one click and apply it directly to your project.

   No registration required, purely online operation, formatting completes in seconds.

Application Scenarios

• Quickly organize messy Java classes or methods to improve code clarity.

• Unify team formats before submitting code and maintain consistent coding standards.

• Display neat, standardized Java examples for learning and teaching.

• Reduce formatting distractions during debugging and focus on logical issues.

How it works

This tool relies on Prettier and prettier-plugin-java, first parsing the Java syntax tree and then regenerating the code in a unified format. It only changes the formatting and does not affect the code logic or execution results. It supports common options such as indentation control, line breaking rules, and alignment optimization, maintaining format consistency while ensuring code readability and standardization.

FQA

1. Will formatting modify my Java program logic?

   No. This tool only adjusts code indentation and formatting; it does not change statement execution logic.

2. Will my code be saved or uploaded?

   No. Code is processed only in the browser and is not stored or uploaded to the server. Local tools are preferred when working with sensitive code.

3. Why do I get parsing errors?

   This usually indicates syntax errors or missing symbols (such as braces or semicolons). Please fix these before formatting.

4. How does it differ from a Java linter or Checkstyle?

   This tool focuses on code formatting and indentation consistency, while a linter or Checkstyle tool focuses on standardization and potential error detection. Using both together can ensure both code readability and quality.
