Initially We have to parse the Java Program and find Classes, constructors, Attributes.
Use that to generate UML diagrams.
Libraries Used : JavaParser - parser used to generate java grammar. PlantUML - Used to generate UML diagrams with Java grammar as input. GraphViz -to generate UML diagrams (its dependency for PlantUML)
Java Compiler Compiler™ (JavaCC™) is the most popular parser generator for use with Java™ applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc.
