## Overview

This small Java payroll application demonstrates a user-to-result workflow in Main: create full- and part-time employees, add them to PayrollSystem, display their details and pay, remove an employee by ID, then display the remaining records. Employee defines shared identity and formats the displayed salary; its two concrete types implement the distinct fixed-monthly and hours-times-rate rules. PayrollSystem keeps the employee collection and handles adding, removing, and displaying it. The graph reflects the sampled calls and README-described pay rules; it does not imply unsampled behavior.

Main entry points: [`Employee.java`](https://github.com/bhuvaneshcloud27/payroll_mgnt_sys/blob/main/Employee.java) (Shared employee), [`PayrollSystem.java`](https://github.com/bhuvaneshcloud27/payroll_mgnt_sys/blob/main/PayrollSystem.java) (Payroll manager), [`Main.java`](https://github.com/bhuvaneshcloud27/payroll_mgnt_sys/blob/main/Main.java) (Demo workflow), [`FullTimeEmployee.java`](https://github.com/bhuvaneshcloud27/payroll_mgnt_sys/blob/main/FullTimeEmployee.java) (Full-time employee)
