Java File Handling & Exception Practice

A collection of Java exercises focused on file I/O, exception handling, and basic data processing — reading/writing text and CSV files, and managing simple record-based data.

Topics Covered

• File Handling — reading and writing .txt and .csv files (employee records, sales data, output generation)
• Exception Handling — try/catch blocks and handling runtime errors gracefully
• 2D Arrays — array-based data storage and traversal
• Record Management — StudentRecordManager and EmployeeSalaryAnalyzer classes simulating simple record-keeping systems

Structure

All source files are under src/. Sample data files (employees.txt, output.csv) support the file-handling exercises.

What I Learned

These exercises built practical comfort with Java's I/O classes (FileReader, Scanner, BufferedReader), exception handling patterns, and structuring simple data-processing logic around files rather than just in-memory arrays.
