A file-driven Java application that reads employee data from a source file, calculates gross pay, and outputs structured payroll information to a destination file. This project demonstrates practical Java skills including file I/O, data parsing, and exception handling in a real-world payroll scenario.
- 📝 User provides file names for input and output during runtime.
- 📂 Reads from a structured employee data file:
- Format:
id|name|hours|payRate
- Format:
- 🧮 Calculates gross pay for each employee:
grossPay = hours * payRate
- 💾 Writes the results to a separate output file:
- Output format:
id,name,grossPay
- Output format:
- ✅ Skips header rows and verifies valid data entries before processing.
Here’s a look at the program running in a terminal environment:
- 🛠️ Run the program in a Java-supported IDE or terminal
- 📤 When prompted:
- Enter the name of the input file (e.g.,
employees.txt) - Enter the desired output file name (e.g.,
payroll.csv)
- Enter the name of the input file (e.g.,
- 📁 Ensure both files are located in the
resourcesdirectory - 📃 The application processes employee records and generates an output file with payroll data
- 📄 Custom File Input/Output for flexibility and real-world practice
- 🧠 Data Parsing & Validation to ensure clean and accurate processing
- 💰 Dynamic Payroll Calculation using user-supplied data
- 🚫 Header Skipping Logic to avoid corrupt output
⚠️ Exception Handling for robust file operations
- 🔁 Looped Input Support for batch file processing
- 📊 Summary Report Generator (e.g., total hours, average pay)
- 📥 GUI Upload Interface for selecting files
- 🧾 Detailed Payroll Breakdown including taxes or overtime pay
- 🧪 JUnit Testing Integration for automated validation
