Java-to-AST-with-Visulization

This project is used for generating an AST for a given Java program. The AST will be stored in .dot format and can be simply visulized by several online tools.

How to run?

• Import the project to eclipse as a Java project.
• Add libraries in lib folder to build path.
• Run Main.java.

Example

• Input program

public class HelloWorld {

    public static void main(String[] args) {
        // Prints "Hello, World" to the terminal window.
        System.out.println("Hello, World");
    }

}

• Output .dot
