The methods-distance from kevin222004

Running:

clone sources
compile:

mvn package

run java -jar methods-distance/target/methods-distance-1.0-SNAPSHOT-jar-with-dependencies.jar --generate-dsm --generate-dot path/to/sources/InputFile.java

This will produce files 'InputFile.java.html' and 'InputFile.java.dot' in working directory.

Alternatively you can try to use web service for generating these files. Web service is hosted at herooku. To get .html file perform GET request at /dsm uri with parameter source_url pointing to url of Java source file. For example: https://methods-distance.herokuapp.com/dsm?source_url=https://raw.githubusercontent.com/checkstyle/checkstyle/b4e884c2ff3bef182b045692b59c1aceae3cb892/src/main/java/com/puppycrawl/tools/checkstyle/Checker.java

To get .dot file perform GET request using /dot uri with parameter source_url. For example https://methods-distance.herokuapp.com/dot?source_url=https://raw.githubusercontent.com/checkstyle/checkstyle/b4e884c2ff3bef182b045692b59c1aceae3cb892/src/main/java/com/puppycrawl/tools/checkstyle/Checker.java

Output .html file will contain design structure matrix of dependencies between methods. This matrix looks like this java file:

Output .dot file will contain graph of method dependencies in .dot format that can be visualized by many viewers. Viewers:

As an example, here is the output for this java file:
