Get the filepath of a File in Java

In this tutorial we are going to see how to get the absolute file path as well as the path of the parent directory of a specific file. This is very useful because it gives a generic way to get the absolute paths of files, independently of the operating system you use. Additionally, among many other uses cases, if you’ve already created a file and you want to create more you don’t have to write the absolute file path again and again.
 
 
 
 
 
 
 
Let’s see the code snippet that follows:

package com.javacodegeeks.java.core;

import java.io.File;

public class AbsoluteFilePathJava {
	
	public static void main(String[] args) {
		
		String filepath ="C:\\Users\\nikos7\\Desktop\\files\\fpahtexample.txt";
		
		File file = new File(filepath);

		String absoluteFilePath = file.getAbsolutePath();
		
		System.out.println("Absolute File path : " + absoluteFilePath);

		String parentDir = absoluteFilePath.substring(0,
				absoluteFilePath.lastIndexOf(File.separator));

		System.out.println("Parent Directory path : " + parentDir);

	}
}

Output:

Absolute File path : C:\Users\nikos7\Desktop\files\fpahtexample.txt
Parent Directory path : C:\Users\nikos7\Desktop\files

 
This was an example how how to get the absolute file path and the parent directory path of a File.
