Coding Conventions in Java :
video
Notes :
- Always give meaningful name to class, variables, methods and so on.
- Use all caps for naming final variables. If it contains two words then separate them using underscore( _ ). Eg: PI, MAX_SIZE
- Packages name should be always small letters as in linux folders names are case sensitive but in windows its not.
- Pascal convention should be used for naming class & interface. i.e First letter of every word should be capital.
- A noun should be used for naming a class as it is used for representing a single real world object.
- An adjective should be used for naming an interface. Eg: Doable, Jumpable, Runnable etc.
- Camel convention should be used for naming data members, variables, references and method name. If they contain only one word then we can name them using small letters.
- A method name should indicate a verb, an action, as it’s a behavior.
Packages & Conventions in Java Interview Questions :
- Do I need to import classes or interface present in java.lang package in my program ?
- Can I import same package or class twice ? Will the JVM load package twice at runtime ?
- What is static import ?
