How to Copy the First 20 Files from a Directory to a Subdirectory in Java?

Copying Files to a Subdirectory within a Directory

In Java, copying files from one directory to another can be achieved using various approaches. To address your specific requirement of copying the first 20 files from a directory to its subdirectory, the following code can be employed:

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class DirectoryCopier {

    public static void main(String[] args) throws IOException {
        // Get the source directory
        File dir = new File("./source_directory");

        // Create the subdirectory
        String subDirName = "subdirectory";
        File subDir = new File(dir, subDirName);
        boolean success = subDir.mkdir();

        // Iterate over the first 20 files in the directory
        int count = 0;
        for (File review : dir.listFiles()) {
            if (count == 20) {
                break;
            }

            // Copy the file to the subdirectory
            Path sourcePath = Paths.get(review.getAbsolutePath());
            Path targetPath = Paths.get(subDir.getAbsolutePath(), review.getName());
            Files.copy(sourcePath, targetPath);

            count++;
        }
    }
}

Copy after login

In this code:

We first obtain the source directory and create the subdirectory within it.
We then iterate over the first 20 files in the directory using a for loop.
For each file, we create the path to both the source and target files.
Finally, we use the Files.copy() method to copy the file to the subdirectory.
