## Overview

This is a console-based employee management system. A user signs in, enters employee details, and uses a menu to register, search, update, delete, or list employees. The UI validates some inputs and delegates employee operations to a service, which manages records in a fixed-size in-memory array. Employee records use department, type, and status enums. The excerpts show these principal links; the exception and constants implementations are present in the tree, but their runtime relationships are not established by the shown code.

Main entry points: [`src/com/takpyamid/ems/ui/UserView.java`](https://github.com/paswanalka/emstask/blob/main/src/com/takpyamid/ems/ui/UserView.java) (Menu and forms), [`src/com/takpyramid/ems/model/Employee.java`](https://github.com/paswanalka/emstask/blob/main/src/com/takpyramid/ems/model/Employee.java) (Employee record), [`src/com/takpyamid/ems/Service/EmployeeService.java`](https://github.com/paswanalka/emstask/blob/main/src/com/takpyamid/ems/Service/EmployeeService.java) (Employee operations), [`src/com/takpyamid/ems/EmployeeRepository/EmployeeRepositary.java`](https://github.com/paswanalka/emstask/blob/main/src/com/takpyamid/ems/EmployeeRepository/EmployeeRepositary.java) (In-memory records)
