what is the purpose of a java class?
Homework Answers
The purpose of the java class is to layout a blueprint of the objects we want to consider using in our program since at the core, java is a object oriented language. Once a class is declared, different objects can be created which resemble the class as they will have their own attribute values and methods as we had defined in the class.
For example: If I am working on an app for employees, I have to create a generic definition of what characteristics (referred to as attributes) an employee generally has and what he/she can do (referred to as methods).
So the characteristics of an employee could be his/her Name, age, designation, department, hourly rate, hours worked etc.
The methods could be like calculate the total hours he/she has worked for in the week.

in java please Purpose: To practice designing a class that can be used in many applications. To write and implement a thorough test plan. You are NOT to use any of the Java API date classes (Gregorian calendar, Date…) except for the constructor method to set the date fields to the current data. Write a class to hold data and perform operations on dates. Ie: January 2, 2019 or 3/15/2018 You must include a toString( ), an equals( ) and...
