With Java 7 and newer you can use the static Files.createDirectory()method of the java.nio.file.Filesclass along with Paths.get.
在 Java 7 和更新版本中，您可以将类的静态Files.createDirectory()方法java.nio.file.Files与Paths.get.
Files.createDirectory(Paths.get("/path/to/folder"));
The method Files.createDirectories()also creates parent directories if these do not exist.
如果父目录不存在，则Files.createDirectories()方法也会创建父目录。

Use the mkdir method on the File class:
在 File 类上使用 mkdir 方法：

The following code would be helpful for the creation of single or multiple directories:
以下代码将有助于创建单个或多个目录：
import java.io.File;
public class CreateSingleOrMultipleDirectory{
public static void main(String[] args) {
//To create single directory
File file = new File("D:\Test");
if (!file.exists()) {
if (file.mkdir()) {
System.out.println("Folder/Directory is created successfully");
} else {
System.out.println("Directory/Folder creation failed!!!");
}
}
//To create multiple directories
File files = new File("D:\Test1\Test2\Test3");
if (!files.exists()) {
if (files.mkdirs()) {
System.out.println("Multiple directories are created successfully");
} else {
System.out.println("Failed to create multiple directories!!!");
}
}
}
}

Better to use mkdirsas:
更好地mkdirs用作：
new File("dirPath/").mkdirs();
mkdirs: also create parent directories if these do not exist.
mkdirs: 如果这些不存在，也创建父目录。
ps: don't forget the ending /that shows explicitly you want to make a directory.
ps：不要忘记/明确显示您要创建目录的结尾。
