## What it is
JavaParser is a Java library that parses Java source code (Java 1.0 through Java 25) into an Abstract Syntax Tree with advanced analysis capabilities, including the JavaSymbolSolver for resolving symbol declarations and types. It enables programmatic analysis, transformation, and generation of Java code.

## Use cases
- parse java source code into an ast
- analyze java code for patterns programmatically
- refactor or transform java source files
- generate java boilerplate code
- resolve variable and method declarations in java code
- build static analysis or linting tools for java
- extract javadoc comments from java sources

## When to choose
- you need to programmatically parse, analyze, transform, or generate Java code on the JVM
- you want symbol resolution to link AST nodes to their declarations and types
- you need support for recent Java language versions with an active release cadence

## When to avoid
- you need to parse languages other than Java
- you want a ready-made linter or formatter rather than building your own tooling
- your project is not on the JVM, since the library is Java-based

## Facets
- artifact type: library
- maturity: active
- function: parser, code-review, developer-tools
- domain: parsers, programming-languages, developer-tools
- platform: jvm, cross-platform
- tags: abstract-syntax-tree, ast, java-parser, symbol-solver, code-generation, code-analysis, javadoc
