Write a class named Employee that has the following fields: • name. The name field references a String object that holds the employee’s name. • idNumber. The idNumber is an int variable that holds the employee’s ID number. • department. The department field references a String object that holds the name of the department where the employee works. • position. The position field references a String object that holds the employee’s job title. The class should have the following constructors: • A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee’s name, employee’s ID number, department, and position. • A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee’s name and ID number. The department and position fields should be assigned an empty string (""). • A no-arg constructor that assigns empty strings ("") to the name, department, and position fields, and 0 to the idNumber field. Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate pro- gram that creates three Employee objects to hold the following data: The program should store this data in the three objects and then display the data for each employee on the screen.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Write a class named Employee that has the following fields:
• name. The name field references a String object that holds the employee’s name.
• idNumber. The idNumber is an int variable that holds the employee’s ID number.
• department. The department field references a String object that holds the name of
the department where the employee works.
• position. The position field references a String object that holds the employee’s
job title.
The class should have the following constructors:
• A constructor that accepts the following values as arguments and assigns them to the
appropriate fields: employee’s name, employee’s ID number, department, and
position.
• A constructor that accepts the following values as arguments and assigns them to the
appropriate fields: employee’s name and ID number. The department and position
fields should be assigned an empty string ("").
• A no-arg constructor that assigns empty strings ("") to the name, department, and
position fields, and 0 to the idNumber field.
Write appropriate mutator methods that store values in these fields and accessor methods that
return the values in these fields. Once you have written the class, write a separate pro- gram
that creates three Employee objects to hold the following data:
The program should store this data in the three objects and then display the data for each
employee on the screen.
