- GUIDED PROJECT 1
- Console-Based Employee Payroll & Directory System
- In this project, you will build a Java console application that maintains an employee directory and calculates payroll. The program will allow the user (HR/admin) to add employees of different types (Full-Time, Part-Time, Intern), view/search/remove employees, and generate payroll reports such as total payroll cost, highest/lowest pay, and average pay. The design will intentionally use Object-Oriented Programming concepts: encapsulation (private fields + getters/setters), constructors and constructor overloading, inheritance, method overriding, polymorphism (processing employees using a common reference type), and basic collection handling using arrays and ArrayList.
