Java Learning Series - Exploring Java File Class: Listing Files and Folders

Today, I explored Java File class and created the mini task using it's methods.

import java.io.File;
import java.io.IOException;

public class FileList {

    public static void main(String[] args){
        File file = new File("/home/saravanan/FullStack/front-end/Back-end/Java");
        File[] files = file.listFiles();
            System.out.println();
            System.out.println(files); //tried to print the entire Objects in an Array
            System.out.println();
            System.out.println("List of Files: ");
            System.out.println();

        for(File obj : files){
            boolean fileStatus = obj.isFile();
//          boolean folderStatus = obj.isDirectory();
            if(fileStatus){
                System.out.println("File Name: " + obj.getName());
                System.out.println("Path : " + obj.getPath());
                System.out.println("Absolute Path : " + obj.getAbsolutePath());
                try{
                System.out.println("Canonical Path : " + obj.getCanonicalPath());
                }catch(IOException io){
                    System.out.println("Canonical Path Error");
                }
                System.out.println("File Length: " + obj.length());
                System.out.println();
            }

//            if(folderStatus){
//                System.out.println(obj.getName());
//            }

        }
            System.out.println();
            System.out.println("List of Folders: ");
            System.out.println();

        for(int i = 0; i<files.length; i++){
            boolean folderStatus = files[i].isDirectory();
        if(folderStatus){
            System.out.println("Folder Name: " + files[i].getName());
            System.out.println("Path : " + files[i].getPath());
            System.out.println("Absolute Path : " + files[i].getAbsolutePath());
            try{
                System.out.println("Canonical Path: " + files[i].getCanonicalPath());
                }catch(IOException io){
                    System.out.println("Canonical Path Error");
                }
            System.out.println("Folder Length: " + files[i].length());
            System.out.println();
        }
        }
    }

}

Output:
