Copying files from one directory to another in Java

To copy a file from one directory to another in Java, you can use the Files.copy method from the java.nio.file package.

Here's an example of how you can use this method to copy a file:

Path source = Paths.get("/path/to/source/file.txt");
Path target = Paths.get("/path/to/target/file.txt");

try {
  Files.copy(source, target, StandardCopyOption.REPLACE_EXISTING);
} catch (IOException e) {
  e.printStackTrace();
}

This code will copy the file at /path/to/source/file.txt to /path/to/target/file.txt, replacing the target file if it already exists.

If you want to copy the file and preserve the attributes of the original file, you can use the COPY_ATTRIBUTES option in addition to the REPLACE_EXISTING option:

Path source = Paths.get("/path/to/source/file.txt");
Path target = Paths.get("/path/to/target/file.txt");

try {
  Files.copy(source, target, StandardCopyOption.REPLACE_EXISTING, StandardCopyOption.COPY_ATTRIBUTES);
} catch (IOException e) {
  e.printStackTrace();
}

This code will copy the file and preserve the last modified time, owner, and permissions of the original file.

I hope this helps! Let me know if you have any questions.
