Listing Content Of Directory In Java 📁 In order to list the contents of a directory, below program can be used. 🗄 This program simply receives the names of the all sub-directory and files in a folder in an Array and then that array is sequentially traversed to list all the contents. 💎

import java.io.*;

public class ListContents {

    public static void main(String[] args) {

    File file =
        new File("//home//user//Documents/");

    String[] files = file.list();

    System.out.println (
      "Listing contents of " + file.getPath()
    );

    for(int i=0 ; i < files.length ; i++) {
         System.out.println(files[i]);
    }

  }

}

Let in LINQ 🔮 A let clause introduces a new range variable with a value that can be based on other range variables. ❌ Sorting by the lengths of usernames without let clause :

var query = 
    from user in SampleData.AllUsers
    orderby user.Name.Length
    select user.Name;

foreach (var name in query)
      Console.WriteLine("{0}: {1}", name.Length, name);

✅ Using a let clause to remove redundant calculations :

var query = 
   from user in SampleData.AllUsers
   let length = user.Name.Length
   order by length
   select new 
   {
       Name= user.Name,
       Length = length
   };

foreach (var entry in query)
    Console.WriteLine("{0}:{1}",entry.Length, entry.Name);

Try to group extension methods into static classes dealing with the same extended type. 📦 Sometimes related classes (such as DateTime and TimeSpan) can be sensibly grouped together. ↔️ But avoid grouping extension methods targeting disparate types such as Stream and string within the same class. ❌ 〰〰〰〰〰〰 #CleanCode #ExtensionMethods @ProgrammingTip

Turn Things Off In HTML 📴 When making responsive sites, you don’t really want users to be able to double tap and zoom, as all your content should be visible. 🖥 To do this you will need to add some code that disables user zooming and scaling.

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />

This code will also enable iOS device to display sites more elegantly when the iPad or iPhone is rotated. 📱 ➖➖➖➖➖➖➖➖➖➖ #html #responsive @ProgrammingTip

JavaScript Clean Code 🛠 Use consistent capitalization 💡 Bad :

const DAYS_IN_WEEK = 7;
const daysInMonth = 30;

const songs = ['Back In Black', 'Stairway to Heaven', 'Hey Jude'];
const Artists = ['ACDC', 'Led Zeppelin', 'The Beatles'];

function eraseDatabase() {}
function restore_database() {}

class animal {}
class Alpaca {}

Good :

const DAYS_IN_WEEK = 7;
const DAYS_IN_MONTH = 30;

const SONGS = ['Back In Black', 'Stairway to Heaven', 'Hey Jude'];
const ARTISTS = ['ACDC', 'Led Zeppelin', 'The Beatles'];

function eraseDatabase() {}
function restoreDatabase() {}

class Animal {}
class Alpaca {}

💚 Retrofit Library 💚 Retrofit turns your REST API into a Java Interface 💎 It’s an elegant solution for organizing API Calls in a project. The request method and relative URL are added with an Annotation , which makes code clean and simple. With annotations, you can easily add a request body, manipulate the URL or headers and add query parameters. 🔥 Adding a return type to a method will make it synchronous, while adding a Callback will allow it to finish asynchronously with success or failure. 🔰 For learn more about Retrofit see : https://github.com/square/retrofit http://square.github.io/retrofit/ #java #android #library @ProgrammingTip

👉 Pointer Tips In C & C++ 👈 🔸Never ever forget to initialize the pointer. This may be simple and easy known stuff but here I would like to add it as an embedded system developer that this was the main cause of many bugs. 🔹Also never change the pointer variable itself unless & until you need to change the pointer. 🔸Also monitor that the pointers are not overlapping if not pointing to same memory location range. 〰〰〰〰〰〰〰〰〰〰〰〰〰〰 #c #cpp #pointer @ProgrammingTip
