The Analyzer does a simple overview of your chatting behavior with someone on WhatsApp. This project still may have some messy code so I am really sorry for this.
The file of the chat can be exported in WhatsApp (Android) or directly in WhatsApp Web (right click on chat -> archive chat).
The exported file will have the following layout:
18.10.17, 17:10 - Person A: I love programming in Java
18.10.17, 17:37 - Person B: Yeah, it is fun
...
The analysis can be done by creating a WamAnalyzer object:
WamAnalyzerImpl analyzer = new WamAnalyzerImpl();
analyzer.analyzeWhatsApp("C:\\Users\\Foo\\Desktop\\ChatWithBar.txt");
The program will display graphs as result of the analysis:
