in java Consider the following problem description and write

in java. Consider the following problem description and write java code:

A company need to store its employees information. Each employee has an id, name, date of birth, phone number and salary. Using the diagram, write your java classes that shows the inheritance between these classes, and consider the following:

Class employee has a method work() which returns the statement “I am an employee”

Class employee overrides toString() method to return the employee information. Or if you don’t what to override toString() you can write your own method to return the employee info. (both ways are accepted)

Each subclass should overrides the method work() to return its work. You need to call work() of the superclass. For example:

Method work() in executive class should returns:

I am an employee.. I work as an executive.

So in each subclass work() method first call it’s parent work() method by using super. Which will return “I am an employee ..” and then add the child own details. in this example “I work as an executive”

Implement the main class Company which constructs objects from the 3 subclasses, and test all of their methods.

Sample Run will result in:

I am an employee.. I work as an executive.

My ID is: 1234567890

My Name is:   John Smith

My Date of Birth is: 1-1-1981

My phone is: 555-555-12345

My Salary is: 12,000

I am an employee.. I work as a Software Engineer.

My ID is: 0987654321

My Name is:   Jane Doe

My Date of Birth is: 1-1-1988

My phone is: 555-555-12345

My Salary is: 10,000

I am an employee.. I work as a Software Manager.

My ID is: 9988776655

My Name is:   Joe Green

My Date of Birth is: 1-1-1978

My phone is: 555-555-12345

My Salary is: 11,000
