General Conventions
- Comment your code (Documentation guidelines)
- One File - One Class
- Don't add packages with a wildcard (e.g. java.lang.* - instead always type the whole package name java.lang.Integer)
- Produce readable code
- Produce efficient code (in this order - first readability, then efficiency)
To ease development while following the rules a checkstyle file can be used. Download and configuration with Eclipse
Naming Conventions
camel case + (reduced) hungarian notation = ARS coding guidline
example camel case: clsHeimoZeilinger (new word –> capital letter)
example hungarian: mnCountOfHeimos (m for member, n typeof integer)
Origin: Hungarian notation - Wikipedia
Basics in (reduced) hungarian notation:
1st letter:
m ... member p ... method parameter i ... interface parameter s ... static variable blank ... function scope ... to be continued
2nd letter:
b ... boolean e ... enum n ... number (integer, long) r ... real (floating point, double) o ... object (also string) g ... generic ... to be continued
File notation (java/eclipse)
clsXYZ ... Classe Files XYZ ... Class Files that contain the method //public static main(String args[])// and that are meant to be used to start the application itfXYZ ... Java Interface tstXYZ ... junit Test Cases tssXYZ ... junit Test Suites
