Fields : Defining Class « Class Definition « Java Tutorial

  1. Fields are variables.
  2. They can be primitives or references to objects.

For example, the Employee class has two fields, age and salary.

public class Employee{
  int age;
  int salary

  1. Field names should follow the camel naming convention.
  2. The initial of each word in the field, except for the first word, is written with a capital letter.
  3. For example: age, maxAge, address, validAddress, numberOfRows.
