Step 4: Writing the Code

Below is the code that merges multiple text files into one using Conholdate.Total for Java.

Steps to Merge Text Files into One using Java

  1. Load the source TXT file by creating a Merger instance and providing the file path.
  2. Add additional TXT files with the join method of the Merger object.
  3. Save the merged result using the save method and specify the output path.

Sample Code

// Load the source TXT file
Merger merger = new Merger("c:\\sample1.txt");

// Add another TXT file to merge
merger.join("c:\\sample2.txt");

// Merge TXT files and save result
merger.save("c:\\merged.txt");

Step 5: Running the Program

Save the Java file and run the program. Ensure the input files (sample1.txt, sample2.txt) are in the project directory. After execution, the console will display “Text files combined successfully.”

Step 6: Verifying the Result

Locate the newly created merged.txt file in the project folder and open it to confirm that the contents of the source files have been combined correctly.

Conclusion

Conholdate.Total for Java offers a reliable way to merge text files quickly. By following the steps in this guide, you can combine multiple .txt files into a single document, simplify file management, and improve productivity. Try the library today to experience seamless text file merging.
