result.saveDocument(Utilities.outputFileName(".pdf"));
GroupDocs.Comparison for Java allows you to compare documents at three levels deep. You can set comparison intensity to be low (compare text word by word with accuracy for imaging grid = 50), middle (compare text character by character with accuracy for imaging grid = 100) or high (compare text character by character with accuracy for imaging grid = 150).
Along with document content, GroupDocs.Comparison for Java API allows to compare text style as well. Font name, size, color, style (bold, italic, underline, small caps, and hyperlinks) and if applicable, under color can also be compared to check difference among compared documents, while words and characters are being compared. For paragraph comparison, alignment, indentation (left indent, right indent), spacing (space after, space before), first line indent and line spacing can also be compared.
