{sec:naming_conventions}

Java has some very handy naming conventions.

• Class names always start with an upper case letter. For example, Scanner, System, Hello
• Method names always start with a lower case letter, and use camelCase to represent multiword method names. for example nextInt()
• Instance variables of a class start with a lower case letter and use camelCase
• Constants are in all upper case letters. for example Math.MAXINT
