Java - how to get the top level folder in which your java code is located?

Question

This is the folder structure. Folder1 ---> Folder2, Folder3. Inside 3 there is java code. How do I make java code which will be able to search the top level folder (ie 1) for a file or folder? Is this even possible ?

Answer 1

I think you can use File's getParent() method to do your desire job.

Answer 2

Use getParent() method to get name of parent or top level directory name.

import java.io.File;
public class DirectoryExample6 {
    public static void main(String args[]){
        File f = new File("D://tutorialData/java");
        String parent = f.getParent();
        System.out.println("Name of parent dir : "+parent);
    }
}

Answer 3

This code gets the path -

String absolutePath = new File(".").getAbsolutePath();
System.out.println(absolutePath);// Shows you the path of your Project Folder
int last = absolutePath.length()-1;
absolutePath = absolutePath.substring(0, last);//Remove the dot at the end of path
System.out.println(absolutePath);
String filePath =  "MyFolderInsideEclipseProject\\file.txt";//You know this
System.out.println(absolutePath + filePath);//Get the full path.
