Skip directory creation if directory already exists

Question

I want to create a Quartz job that reads .csv files and moves them when the file is processed. I tried this:

@Override
public void execute(JobExecutionContext context) {

    File directoryPath = new File("C:\\csv\\nov");
    // Create a new subfolder called "processed" into source directory
    try {
        Files.createDirectory(Path.of(directoryPath.getAbsolutePath() + "/processed"));
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
    .......................
}

When I run the code a second time I get the error:

Caused by: java.nio.file.FileAlreadyExistsException: C:\csv\nov\processed

Is there some way to make a check for this directory and skip directory creation? I can remove the line throw new RuntimeException(e); but I'm looking for a better way to handle the case.

Did you mean:

try {
    Path path = Path.of(directoryPath.getAbsolutePath() + "/processed");

    // Check first if the file not exist
    if (!Files.exists(path)) {
        Files.createDirectory(path);
    }
} catch(..)
