A Swing-based Java utility that processes integer data files, reformats the output, and calculates comprehensive statistics including minimum, maximum, total, and average values.

• File Processing: Read and validate integer data files
• Formatted Output: Write data with 10 numbers per line
• Statistical Analysis: Calculate min, max, total, and average
• Input Validation: Verify data count and format integrity
• GUI Interface: User-friendly file selection dialogs
• Sample Data: Includes multiple test files (10-700 integers)

• First integer: count of following integers
• Subsequent integers: data values (space or newline separated)

• Line 1: File size (count)
• Lines 2-n: Data values (10 per line)
• Final lines: Statistics (one per line)
  • Minimum value
  • Maximum value
  • Total sum
  • Average (2 decimal places)
