What Fields are the in java?

Fields are variables.
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

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