Setting Up Your Java Project

To get started, create a new Java project in your IDE and add the Aspose.Words library to your project dependencies.

Step 1: Load the Documents

The first step in comparing documents is to load the documents you want to compare. You can use the following code snippet to load two documents:

// Load the original document
Document docOriginal = new Document("original_document.docx");

// Load the modified document
Document docModified = new Document("modified_document.docx");

Replace "original_document.docx" and "modified_document.docx" with the paths to your own documents.

Step 2: Compare Documents

Now that you have loaded the documents, it’s time to compare them. Aspose.Words provides a convenient method for comparing documents. Here’s how you can do it:

// Compare the two documents
DocumentComparer comparer = new DocumentComparer(docOriginal, docModified);
comparer.compare();

Step 3: Save the Comparison Result

After comparing the documents, you’ll want to save the result. Aspose.Words allows you to save the comparison result as a new document. Here’s how:

// Save the comparison result
comparer.save("comparison_result.docx");

Step 4: Review the Differences

Now that you have the comparison result saved, you can review the differences between the original and modified documents. Open “comparison_result.docx” to see the changes highlighted.

Conclusion

Comparing documents for differences using Aspose.Words for Java is a straightforward process that can greatly enhance your document management workflow. With this powerful API, you can ensure the accuracy and consistency of your documents with ease.
