The Apache Software Foundation created Apache Commons, a reusable, open-source Java component. It has many libraries that apply to various tasks, such as text processing, file handling, and data manipulation. Due to its simplicity and extensive feature set, Apache Commons is frequently used in Java-based applications and is a favorite among developers. The Apache License, under which the Apache Commons libraries provide, permits their unrestricted use in both commercial and non-commercial applications. The ability to download files from a URL using Apache Commons in Java can be helpful in various situations, like downloading files from a server, web scraping, data mining, file transfer programs, downloading files for data analysis, machine learning, and more.
You can use the FileUtils.copyURLToFile() method in Java to download a file from a URL using Apache Commons. This approach accepts the following arguments:
- source: The download URL for the file you want.
- dest: The destination file where will save the downloaded content
The Apache Commons IO library's FileUtils.copyURLToFile() method lacks built-in timeout support. To set the CONNECT TIMEOUT and READ TIMEOUT settings, you can use the java.net.URLConnection class, the underlying class utilized by the FileUtils.copyURLToFile() function to download files from URLs.
The following is an illustration of how you could use this technique to download a file from a URL:

- Copy the code using the "Copy" button above, and paste it in a Java file in your IDE.
- Add dependent library and import in java file.
- Run the file to generate csv file.
I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.
I found this code snippet by searching for "download files using Apache in java" in kandi. You can try any such use case!
I tested this solution in the following versions. Be mindful of changes when working with other versions.
- The solution is created in open-jdk-11.0.8.
- The solution is tested on Apache commons-IO 2.6 version.
Using this solution, we are able to download an file using the Apache commons-IO library in Java with simple steps. This process also facilities an easy to use, hassle free method to create a hands-on working version of code which would help us write a file from the download URL in Java.
