mkdirs在桌面中创建文件夹，而不是在项目文件夹中

import java.io.File;

public class CreateFolder {
    public static void main(String[] args) {
        String desktopPath = System.getProperty("user.home") + File.separator + "Desktop";
        String folderName = "NewFolder";

        File folder = new File(desktopPath, folderName);
        if (!folder.exists()) {
            boolean created = folder.mkdirs();
            if (created) {
                System.out.println("文件夹创建成功");
            } else {
                System.out.println("文件夹创建失败");
            }
        } else {
            System.out.println("文件夹已存在");
        }
    }
}
