Description: To find the size of a folder in Java, the `File` class from the `java.io` package is commonly used. The process involves recursively traversing the folder and summing the sizes of all files within it. First, a `File` object representing the folder is created, and the `listFiles()` method is called to retrieve the contents of the folder. If a file is a regular file, its size can be obtained using the `length()` method. If a directory is encountered, the same process is applied recursively to all files and subdirectories within it. The total size is accumulated by adding the sizes of the files. For large directories or more complex operations, Java's `nio` package or streams can also be utilized for more efficient handling of file traversal.
