java_validate TBE files

[DeviPriya-Kolla]

Description:
Develop a validation tool in Java to ensure that TBE files conform to the TBE format standard, verifying both structural integrity and content accuracy.

Developer Notes:

• Implement a core (for example., validate_tbe_file) function to handle each validation step.
• Use various sub-functions for different types of checks.
• Generating a summary report which includes all sections, checks and errors/warnings to understand file compliance status.

Acceptance Criteria:

• Confirm that TBE files are parsed and loaded without errors.
• Verify the presence of BGN and EOT markers, ensuring that each section starts and ends correctly.
• Ensure all required sections (global metadata, TBL, ATT, CMT) are present and follow the correct sequence.
• Check all sections start with BGN and end with EOT markers, ensuring completeness.
• Implement checks using sub-functions like validate_structure, validate_markers, validate_sections and validate_data_types.
• Provide detailed error messages specifying the section and type of issue.
• Generate a summary report
  • list of sections validated
  • summary of errors, warnings, or missing fields.
  • overall pass/fail result
• Provide clear usage documentation in Java, showing how the validation can be integrated into data pipelines.
• Provide options to export the validation reports in various formats (e.g., JSON, CSV, PDF)
