## Overview

This is a small, interactive Java leave-tracking case study. The CLI in `Main` creates one in-memory employee, validates and submits a leave request, and displays either record. The domain classes hold and display those records; there is no persistent store. The README describes HR review and approval or rejection, but the sampled code only initializes requests as pending and exposes no review or decision workflow.

Main entry points: [`src/Main.java`](https://github.com/eusha1879/java-leave-tracking-system/blob/main/src/Main.java) (CLI workflow), [`src/Employee.java`](https://github.com/eusha1879/java-leave-tracking-system/blob/main/src/Employee.java) (Employee record), [`src/LeaveRequest.java`](https://github.com/eusha1879/java-leave-tracking-system/blob/main/src/LeaveRequest.java) (Leave request)
