HashMap<K,V>: Hash table based implementation of the Map interface.
HashSet: This class implements the Set interface, backed by a hash table (actually a HashMap instance).
Hashtable<K,V>: This class implements a hash table, which maps keys to values.
IdentityHashMap<K,V>: This class implements the Map interface with a hash table, using reference-equality in place of object-equality when comparing keys (and values).
LinkedHashMap<K,V>: Hash table and linked list implementation of the Map interface, with predictable iteration order.
LinkedHashSet: Hash table and linked list implementation of the Set interface, with predictable iteration order.
LinkedList: Doubly-linked list implementation of the List and Deque interfaces.

How Does java.lang package is used in java?

Learning Java Programming Made Easy

Java.lang package in Java

How to Send an Email through Java Programming

Learning Java Programming Made Easy

Java - Sending Email

To send an e-mail using your Java Application is simple enough but to start with you should have JavaMail API and Java Activation Framework (JAF)installed on your machine.

You can download the latest version of JavaMail (Version 1.2) from Java's standard website.

You can download the latest version of JAF (Version 1.1.1)from Java's standard website.

Download and unzip these files, in the newly created top-level directories, you will find a number of jar files for both the applications. You need to add mail.jar and activation.jar files to your CLASSPATH.

Send a Simple E-mail

Here is an example to send a simple e-mail from your machine. It is assumed that your localhost is connected to the Internet and capable enough to send an e-mail.

// File Name SendEmail.java

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class SendEmail {

   public static void main(String [] args) {    
      // Recipient's email ID needs to be mentioned.
      String to = "abcd@gmail.com";

      // Sender's email ID needs to be mentioned
      String from = "web@gmail.com";

      // Assuming you are sending email from localhost
      String host = "localhost";

      // Get system properties
      Properties properties = System.getProperties();

      // Setup mail server
      properties.setProperty("mail.smtp.host", host);

      // Get the default Session object.
      Session session = Session.getDefaultInstance(properties);

      try {
         // Create a default MimeMessage object.
         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.
         message.setFrom(new InternetAddress(from));

         // Set To: header field of the header.
         message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

         // Set Subject: header field
         message.setSubject("This is the Subject Line!");

         // Now set the actual message
         message.setText("This is actual message");

         // Send message
         Transport.send(message);
         System.out.println("Sent message successfully....");
      } catch (MessagingException mex) {
         mex.printStackTrace();
      }
   }
}

What is Difference Between Windows Web Hosting and Linux Web Hosting..?

Difference Between Windows Web Hosting and Linux Web Hosting

Introduction :

Linux and Windows are two different types of operating systems.
Linux is the most popular operating system for web servers.
Since Linux-based hosting is more popular, it has more of the features web designers expect. So unless you have websites which need specific Windows applications, Linux is the preferred choice.

Windows Specific Applications:

Windows applications which require a Windows server:

ASP Classic
ASP.NET
MSSQL (Microsoft SQL Server)
MS Access (Microsoft Access)
Visual Basic Development
C#
Remote Desktop (dedicated server only)

Windows Dedicated Servers can support additional Windows-specific applications. For some applications, you may need to purchase a license and install the software on your Windows dedicated server.

Microsoft Exchange (requires license & Installation)
Microsoft SharePoint (requires license & Installation)

Linux Specific Applications:

Applications that require a Linux-based server.

SSH
Scripts or applications that require specific Apache modules

Control Panels:

Windows servers and Linux servers use different control panels.

cPanel is available on all Linux-based hosting plans, such as Linux Shared, Reseller, VPS and Linux Dedicated Servers.
WHM (Web Host Manager) is available on Linux Reseller, VPS and Dedicated Servers.
Plesk is available on Windows Shared and Dedicated Servers.

File Names:

Another difference between Linux and Windows servers is that Linux files are case sensitive while Windows files are not.

For example:

On a Linux server, home.html and Home.html are different names.
On a Windows server, home.html, Home.html, and HOME.HTML are all the same name.

Server Security:

Although many people consider Linux to be more secure than Windows, both operating systems are equally secure. Security really depends more on the server setup and the administrators running the server. All of HostGator's managed servers are maintained with the latest security and performance patches and configured for optimal security.
