How do I load a file from resource folder?

To load a file from the resource folder in a Java application, you can use the ClassLoader and getResourceAsStream method.

Here is an example of how you can do this:

InputStream inputStream = getClass().getClassLoader().getResourceAsStream("file.txt");

This will load the file.txt file from the resource folder.

Alternatively, you can use the getResource method to obtain a URL to the file, and then use the URL.openStream method to open an InputStream to the file.

Here is an example of how you can do this:

URL url = getClass().getClassLoader().getResource("file.txt");
InputStream inputStream = url.openStream();

Note that the resource folder is typically located in the classpath of the application, and it is used to store resources that are required by the application at runtime, such as configuration files, images, and so on.
