User-defined identifiers come in 3 types: classes, methods, and variables. Follow the coding rules for identifiers. Keep in mind that method identifiers usually begin with an action word.

Here are the coding formats for each type of identifier:

Identifier Type	Format	Example
Class:	accessModifier class nameOfClass	public class Employee
Method:	accessModifier static returnType nameOfMethod()	public static void hireEmployee()
Variable:	dataType nameOfVariable = initialValue;	String employee = ;
