How to get and use the path of a folder in eclipse project?

Question

I create a new folder Fold inside my eclipse project Proj. How do I get the path of Fold relative to Proj ? This folder will be used as place to store serialized objects. Will I be able to serialize and de-serialize my code using this relative path ?

Answer 1

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL url = classLoader.getResource("path/folder");

or

URL url = getClass().getResource("path/folder");

Answer 2

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.
