How to create a directory using File.getParentFile().getName() with relative path

Question

I am having an input folder say c:\files\input\ that contains my list of files that I am using.

How do I use the above to create say c:\files\output\ and copy the files from the input folder to the output folder?

My c:\files\input is read from an object, say

String inputFolder = dataMap.getString("folder");// this will get c:\files\input\

Do you want copy one directory contains list of files to another directory? — Sai Ye Yan Naing Aye, Feb 27 '14 at 08:28
I'm not sure if that's the best way but for my case I actually do have some logic, thus the copying of file should be immediately after logic is done. — prog rice bowl, Feb 27 '14 at 08:31

You got path of folder in variable inputFolder now do as follows.

String inputFolder = dataMap.getString("folder");

File dir = new File(inputFolder);
if(dir.mkdirs()){
    System.out.println("Directory created");
}else{
    System.out.println("Directory Not Created");
}

Some users are just jealous about you all having high reputation, maybe. I even have my own questions downvoted before. :( – prog rice bowl Feb 27 '14 at 08:19

You can use FileUtils from org.apache.commons.io library

FileUtils.copyDirectory(srcDir, destDir);

so in your case:

File file = new File(inputFolder);
String parentDir = file.getParentFile().getAbsolutePath();
File outputDir = new File(parentDir, "output");
if(!outputDir.exsit()) {
    outputDir.mkdir();
}
FileUtils.copyDirectory(inputFolder, outputDir);

To Create the directory you can refer to the below code

File file = new File("c:\\files\\output");
        if (!file.exists()) {
            if (file.mkdir()) {
                System.out.println("Directory is created!");
            } else {
                System.out.println("Failed to create directory!");
            }
        }

To copy files from a directory to another directory.. refer to the following link it gives a good explanation with source code examples

Hi @Sandy_Chelsea, I don't want to "hardcode" the path as you had written File file = new File("c:\\files\\output"); – prog rice bowl Feb 27 '14 at 08:24
if you dont want to hardcode populate the value from the Object you mentioned in your post like File file = new file(someObject.filepath); – Sandy Feb 27 '14 at 08:35
This one is a duplicate answer. – Prasad Feb 27 '14 at 10:19
