Employee and Salary Class - java programming fundamentals II

I wrote this code myself based off the prompt my professor provided in the first image, yet I struggle to understand the direction. Based off previous assignments, and this chapter, he wants me utilize inheritance, arrays, objects and constructors. However, this is an online course so I am struggling a lot with the technicalities of things.

Your help is much appreciated.

Employee and Salary Class Define a class Employee with data members as int employee_id - To store employee ID. String employee_name - To store the name of the employee. Define class Salary which inherits Employee class and has the following characteristics Data members String designation - To store employee designation. double monthly_salary - To store salary of the employee. Methods constructor Salary(int employee_id, String employee_name, String designation, double monthly_salary) - Invokes a superclass constructor and initialize data members. void display() - To display details of employees whose earning is more than 20,000.
