                                       String prefix,
                                       FileAttribute<?>... attrs)

public static Path createTempDirectory(String prefix,
                                       FileAttribute<?>... attrs)
                                throws IOException

This method works in exactly the manner specified by the above method; Files#createTempDirectory(Path,String,FileAttribute[]) method for the case that the dir parameter is the temporary-file directory.


Examples


package com.logicbig.example.files;

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

public class CreateTempDirectoryExample {

    public static void main(String... args) throws IOException {
        Path path = Files.createTempDirectory("myFile");
        System.out.println(path);
        boolean b = Files.isDirectory(path);
        System.out.println(b);
    }
}

Output

public class CreateTempDirectoryExample2 {

    public static void main(String... args) throws IOException {
        Path basePath = Paths.get("c:\\myDir");
        System.out.printf("base dir: %s, exists: %s%n",
                basePath, Files.exists(basePath));

        Path path = Files.createTempDirectory(basePath, "test");
        System.out.printf("Temp directory created: %s, exists: %s%n",
                path, Files.exists(path));
    }
}

Output

base dir: c:\myDir, exists: true
