Code Convention

Classes

1. When you extend existing well-known class, attach the parent class name as suffix.

    e.g.) When making a fragment for community feature: CommunityFrgment.java

2. If you are making abstract class, attach Base as suffix,

    e.g.) Abstract base class of fragment which will be used in Galaxy Care: FragmentBase.java

3. Class name should be like XxxYyyy

 

Variables

1. When you declare instance variables of well-known classes, attach the class name as suffix.

    e.g.) Declaring TextView variable for decstription: descriptionTextView

           Decalring ImageView for icon: iconImageView

2. When you declaring member variables, it may be protected, private.

    the member variable should be started with underscore.

    e.g.) Declaring member variable for icon image: private ImageView
_iconImageView;

3. Static final member variable should be all uppercase.

    e.g.) Declaring static server url: private static final String _SERVER_URL = "...";

4. Variables name should be like: xxxYyy

 

Codes

1. Always use braces even when only one line in the loop or if-else.

   e.g.)

       if(a < 0) {

           a = 0;

       }

2. If you use collections like Map, List, etc., I encourage you to set it final and initialize it in the member.

    e.g.) private final Map<String, String> _nameJobMap = new HashMap<>();

3. If possible declare as most possible abstract interface as type.

    e.g.) private Map<String, String> _nameJobMap = new
HashMap<>();

           private List<String> _nameList = new ArrayList<>();
