Employee Wage Calculator

An object-oriented console application developed as a homework project for University of Pécs Faculty of Engineering and Information Technology 2nd Year Computer Science Engineering BSc - Programming 2 course. Built in Java to maintain and calculate employee wages with automated data processing capabilities.

What it does

• Automated data import: processes work hours data files from

  TEXT

  data/work_hours

  folder
• Employee management: reads employee catalog from

  TEXT

  data/employee_catalog.txt

• Wage calculations: computes normal wages, overtime pay, and missed hours penalties
• Sorted reporting: displays employee wages alphabetically by name
• Priority reporting: lists employees by missed hours (most critical first)
• Financial summaries: calculates total company payroll including wages, overtime, and productivity losses

Why it matters

• Real-world application: demonstrates practical payroll management systems
• Data processing skills: showcases file I/O and automated data import capabilities
• Business logic: implements complex wage calculation algorithms with overtime and penalty systems
• Clean architecture: follows object-oriented design principles for maintainable code

Features (detailed)

1. Data Sources

   • Automatic discovery of work hours files in designated folder
   • Structured employee catalog with consistent data format
   • Robust file parsing with error handling

2. Calculation Engine

   • Standard wage computation based on hours worked
   • Overtime pay calculation with premium rates
   • Penalty calculation for missed hours based on base wage
   • Total compensation summaries

3. Reporting System

   • Alphabetical employee wage listing
   • Missed hours priority ranking (most missed hours first)
   • Comprehensive financial summaries for management

4. User Interface

   • Console-based menu system for different report types
   • Clear, formatted output for easy reading
   • Interactive options for different calculations

Technical Implementation

• Language: Java (Object-Oriented Programming)
• Architecture: Clean separation between data models, calculation logic, and presentation layers
• Data Processing: File system integration for automated data import
• Error Handling: Robust parsing with validation and logging capabilities

Core Features in Action

// Employee wage calculation logic
public double calculateTotalWage() {
    double normalWage = regularHours * hourlyRate;
    double overtimeWage = overtimeHours * hourlyRate * OVERTIME_MULTIPLIER;
    double missedHoursPenalty = missedHours * hourlyRate * PENALTY_RATE;
    return normalWage + overtimeWage - missedHoursPenalty;
}

Project Context

This project was completed as part of the Programming 2 course curriculum, demonstrating fundamental software engineering principles including:

• Object-oriented design patterns
• File I/O operations
• Data structures and algorithms
• Clean code practices
• Error handling and validation

The application successfully processes real employee data and provides actionable business insights through comprehensive wage analysis and reporting.
