Java program that utilizes JavaParser to analyze the control flow of Java source code and generate a Control Flow Graph (CFG). The tool extracts information about conditional statements, branches, and statements within code blocks to provide insights into the program's structure.

Java CFG Analyzer

This project is a simple Java Control Flow Graph (CFG) Analyzer using JavaParser.

Overview

The Java CFG Analyzer parses a Java source file, extracts control flow information, and generates a CFG in JSON format. The project demonstrates how to use JavaParser to work with Abstract Syntax Trees (AST) and analyze the structure of if-else blocks.

Usage

1. Clone the repository:

   git clone https://github.com/Chayan199916/java-cfg-analyzer.git
   

2. Navigate to the project directory:

   cd java-cfg-analyzer
   

3. Place your Java source files in the src/main/resources directory.

   For example, if your file is named "Sample2.java":

   • src
     • main
       • resources
         • Sample2.java

4. Build the project using Maven:

   mvn clean package
   

5. Run the Java CFG Analyzer:

   mvn exec:java
   

6. This will generate the control flow graph (CFG) in JSON format in the target directory and display the number of distinct paths.

Dependencies

JavaParser: A Java library for parsing and analyzing Java source code.

Gson: A Java library for JSON serialization and deserialization.
