Java Merge Example

Text (.txt) files are a fundamental part of data storage and manipulation in many software applications. There are situations where you may need to combine multiple text files into a single file for easier management and processing. In this blog post, we will explore how to achieve this using Conholdate.Total for Java, a powerful text file joiner API.

Step 1: Setting up the Development Environment

To get started, make sure you have the following in place:

  • Java Development Kit (JDK) installed on your system.
  • Integrated Development Environment (IDE) of your choice (e.g., Eclipse, IntelliJ IDEA).

Step 2: Obtaining Conholdate.Total for Java

Conholdate.Total for Java is a comprehensive suite of file format APIs that includes the text file joiner API we need for our task. The installation procedure of this Java library is very simple. The Maven users can simply add the following configurations in the pom.xml file.

Step 3: Creating a New Java Project

Launch your chosen IDE and create a new Java project. Give it a suitable name and specify the project location. Set up the project with the appropriate JDK.

Step 4: Writing the Code

Now, let’s dive into the code that combines multiple text files into a single file using Conholdate.Total for Java.

Steps to Merge Text Files into One using Java:

  1. Load the source TXT file by creating an instance of the Merger class and specifying the path of the file to be merged.
  2. Add TXT files to the merging process using the join method of the Merger object. Specify the path of the additional TXT files.
  3. Save the merged result by calling the save method of the Merger object and providing the desired path for the output file.

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. Make sure the input files (“sample1.txt”, “sample2.txt”) are present in the project directory. After execution, you should see the “Text files combined successfully.” message in the console.

Step 6: Verifying the Result

Check the project directory for the newly created “merged.txt” file. Open it to confirm that the contents of the input files have been successfully combined into a single file.

Conclusion:

In conclusion, Conholdate.Total for Java provides a powerful solution for merging text files seamlessly. By following the steps outlined in this blog post, you can easily combine multiple text files into a single file. The TXT file joiner library simplifies text file management and enhances productivity. Try it out and experience the convenience and efficiency of merging text files with ease.
