How To Make a Line Break/New Line in Java

Line Break or New Line : I hope you understand what it is, in HTML you use <br> tag to make a new line so in Java if you want to make a new line it's not that hard but it has several methods depends on the platform.

Coming to the point, most of the java beginners think this is the one and only way to make a new line : System.out.println("\n"); but It's not true.. let me tell you something you might think that whatever you program using java will work on other java supported platforms, YES! they will work on other platforms but there are few things that has to be changed in order to get the functions work.. for example this tutorial; this line of code : System.out.println("\n"); would make a new line only on Windows. As I said before there are few things that are different from platform to platforms.

If you want to make a new line on Mac you must use this : System.out.println("\r"); and for Linux you have to use this : System.out.println("\r\n");. So I came up with something that works on all the platforms, It's pretty simple and works perfectly.

First you need to make a public string and set the value to make a new line(You can also just make normal string and set the value)
Add this line of code before your main event

public static String breakline = System.getProperty("line.separator");

Whenever you need to make a new line just use this line of code 
You can add this wherever you want to

System.out.println(breakline);

How To Read A Text File Hosted Online To A String

 

So I got a email asking how to do this, I haven't done this before so went through some Google searches and found how to do this. It was pretty easy. I'll just share the code here maybe it'll be useful for someone.

You need these namespaces :

Imports System.IO
Imports System.Net

Event :

Dim TXT As String = "http://www.ultimateprogrammingtutorials.info/robots.txt"
Dim WC As WebClient = New WebClient()
Dim Read As StreamReader = New StreamReader(WC.OpenRead(TXT))
Dim STR As String = Read.ReadToEnd
TextBox1.Text = STR

• Replace the TXT string value with your .txt link. 
• You can also write into a richtextbox or whatever you want(I used textbox1 for example) 

I hope you learned something from this snippet.

How To Check If Directory Exists In VB.NET And C#

I have had some hard times in solving this problem not these days but sometime ago when I started programming so I think this would be helpful for anyone who has started programming..

Here's the code to check if the directory exists in VB.NET :

Try
            If System.IO.Directory.GetDirectories("PATH").Length > 0 Then
                MsgBox("directory exists")

            End If
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

All you need to do is replace PATH with the directory you want to check... length > 0 identifies if the directory exists.

Here's the code for C# :

try
            {
                if (System.IO.Directory.GetDirectories("PATH").Length > 0)
                {
                    MessageBox.Show("directory exists");

                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

Do the same thing as given for VB.NET code.
