Employee Management System (Java)

A simple console-based Employee Management System in Java that supports multiple employee types, including Salaried, Hourly, Commission, and Base Plus Commission employees. The system allows you to add, remove, and view employee details using a menu-driven interface.

Features

• Add Employees: Supports four types of employees.
• Remove Employees: Remove by Social Security Number (SSN).
• View All Employees: Display a list of all employees.
• View Employee Details: Search and display details by SSN.
• Input Validation: Prevents duplicate SSNs.
