在Windows和Linux计算机上使用Java程序创建新文件夹

Question

如何在Windows和Linux计算机上使用Java代码创建文件夹？

Answer 1

new File("/path/to/folder").mkdir();

If you want to created nested folders (ie more than one folder on the path may be missing), then use mkdirs() . See java.io.File .

Note that forward slashes would normally not work on windows, but Java normalizes the path and translates forward to backward slashes.

Answer 2

 try{
    String strDirectoy ="test";
    String strManyDirectories="dir1"+File.Separator+"dir2"+File.Separator+"dir3";

    // Create one directory
    boolean success = (new File(strDirectoy)).mkdir();
    if (success) {
      System.out.println("Directory: " + strDirectoy + " created");
    }    


    // Create multiple directories
    success = (new File(strManyDirectories)).mkdirs();
    if (success) {
      System.out.println("Directories: " + strManyDirectories + " created");
    }

    }catch (Exception e){//Catch exception if any
      System.err.println("Error: " + e.getMessage());
    }
