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.

What is Java List and List Iterator?

Learning Java Programming Made Easy

List And List Iterator

Java List Interface:

List Interface is the subinterface of Collection.It contains methods to insert and delete elements in index basis.It is a factory of ListIterator interface.

Java List Example

1. import java.util.*;  
2. public class ListExample{  
3. public static void main(String args[]){  
4. ArrayList<String> al=new ArrayList<String>();  
5. al.add("Amit");  
6. al.add("Vijay");  
7. al.add("Kumar");  
8. al.add(1,"Sachin");  
9. System.out.println("Element at 2nd position: "+al.get(2));  
10. for(String s:al){  
11.  System.out.println(s);  
12. }  
13. }  
14. }

Java ListIterator Interface:

ListIterator Interface is used to traverse the element in backward and forward direction.

Example of ListIterator Interface

1. import java.util.*;  
2. public class TestCollection8{  
3. public static void main(String args[]){  
4. ArrayList<String> al=new ArrayList<String>();  
5. al.add("Amit");  
6. al.add("Vijay");  
7. al.add("Kumar");  
8. al.add(1,"Sachin");  
9. System.out.println("element at 2nd position: "+al.get(2));  
10. ListIterator<String> itr=al.listIterator();  
11. System.out.println("traversing elements in forward direction...");  
12. while(itr.hasNext()){  
13. System.out.println(itr.next());  
14. }  
15. System.out.println("traversing elements in backward direction...");  
16. while(itr.hasPrevious()){  
17. System.out.println(itr.previous());  
18. }  
19. }  
20. }

What is Encapsulation in Java Programming?

Learning Java Programming Made Easy

Encapsulation in Java

Encapsulation in java is a process of wrapping code and data together into a single unit, for example capsule i.e. mixed of several medicines.

We can create a fully encapsulated class in java by making all the data members of the class private. Now we can use setter and getter methods to set and get the data in it. The Java Bean class is the example of fully encapsulated class.

Advantage of Encapsulation in java

By providing only setter or getter method, you can make the class read-only or write-only. It provides you the control over the data. Suppose you want to set the value of id i.e. greater than 100 only, you can write the logic inside the setter method.

1. //save as Student.java  
2. package com.funlearn;  
3. public class Student{  
4. private String name;  
5.    
6. public String getName(){  
7. return name;  
8. }  
9. public void setName(String name){  
10. this.name=name  
11. }  
12. }  

1. //save as Test.java  
2. package com.funlearn;  
3. class Test{  
4. public static void main(String[] args){  
5. Student s=new Student();  
6. s.setName("vijay");  
7. System.out.println(s.getName());  
8. }  
9. }  

How Sting Joiner Class Works in JAVA Programming

Learning Java Programming Made Easy

Java StringJoiner

Java added a new final class StringJoiner in java.util package. It is used to construct a sequence of characters separated by a delimiter. Now, you can create string by passing delimiters like comma(,), hyphen(-) etc. You can also pass prefix and suffix to the char sequence.

Java StringJoiner Example

1. // importing StringJoiner class  
2. import java.util.StringJoiner;  
3. public class StringJoinerExample {  
4.     public static void main(String[] args) {  
5.         StringJoiner joinNames = new StringJoiner(","); // passing comma(,) as delimiter   
6.           
7.         // Adding values to StringJoiner  
8.         joinNames.add("Rahul");  
9.         joinNames.add("Raju");  
10.         joinNames.add("Peter");  
11.         joinNames.add("Raheem");  
12.                   
13.         System.out.println(joinNames);  
14.     }  
15. }  

Java StringJoiner Example: adding prefix and suffix

1. // importing StringJoiner class  
2. import java.util.StringJoiner;  
3. public class StringJoinerExample {  
4.     public static void main(String[] args) {  
5.         StringJoiner joinNames = new StringJoiner(",", "[", "]");   // passing comma(,) and square-brackets as delimiter   
6.           
7.         // Adding values to StringJoiner  
8.         joinNames.add("Rahul");  
9.         joinNames.add("Raju");  
10.         joinNames.add("Peter");  
11.         joinNames.add("Raheem");  
12.                   
13.         System.out.println(joinNames);  
14.     }  
15. }  

StringJoiner Example: Merge Two StringJoiner

1. // importing StringJoiner class  
2. import java.util.StringJoiner;  
3. public class StringJoinerExample {  
4.     public static void main(String[] args) {  
5.   
6.         StringJoiner joinNames = new StringJoiner(",", "[", "]");   // passing comma(,) and square-brackets as delimiter   
7.           
8.         // Adding values to StringJoiner  
9.         joinNames.add("Rahul");  
10.         joinNames.add("Raju");  
11.   
12.         // Creating StringJoiner with :(colon) delimiter  
13.         StringJoiner joinNames2 = new StringJoiner(":", "[", "]");  // passing colon(:) and square-brackets as delimiter   
14.           
15.         // Adding values to StringJoiner  
16.         joinNames2.add("Peter");  
17.         joinNames2.add("Raheem");  
18.   
19.         // Merging two StringJoiner  
20.         StringJoiner merge = joinNames.merge(joinNames2);   
21.         System.out.println(merge);  
22.     }  
23. }

How to use URLConnection class in Java Programming

Learning Java Programming Made Easy

Java Connection Class:

The Java URLConnection class represents a communication link between the URL and the application. This class can be used to read and write data to the specified resource referred by the URL.

The openConnection() method of URL class returns the object of URLConnection class. Syntax:

public URLConnection openConnection()throws IOException{}

Example:

1. import java.io.*;  
2. import java.net.*;  
3. public class URLConnectionExample {  
4. public static void main(String[] args){  
5. try{  
6. URL url=new URL("http://www.javatpoint.com/java-tutorial");  
7. URLConnection urlcon=url.openConnection();  
8. InputStream stream=urlcon.getInputStream();  
9. int i;  
10. while((i=stream.read())!=-1){  
11. System.out.print((char)i);  
12. }  
13. }catch(Exception e){System.out.println(e);}  
14. }  
15. }

How Does URL Programming works in Java Development

Learning Java Programming Made Easy


Java URL:

The Java URL class represents an URL. URL is an acronym for Uniform Resource Locator. It points to a resource on the World Wide Web. For example:

A URL contains many information:

1. Protocol: In this case, http is the protocol.
2. Server name or IP Address: In this case, www.javatpoint.com is the server name.
3. Port Number: It is an optional attribute. If we write http//ww.javatpoint.com:80/sonoojaiswal/ , 80 is the port number. If port number is not mentioned in the URL, it returns -1.
4. File Name or directory name: In this case, index.jsp is the file name.

Method	Description
public String getProtocol()	it returns the protocol of the URL.
public String getHost()	it returns the host name of the URL.
public String getPort()	it returns the Port Number of the URL.
public String getFile()	it returns the file name of the URL.
public URLConnection openConnection()	it returns the instance of URLConnection i.e. associated with this URL.

1. //URLDemo.java  
2. import java.io.*;  
3. import java.net.*;  
4. public class URLDemo{  
5. public static void main(String[] args){  
6. try{  
7. URL url=new URL("http://www.javatpoint.com/java-tutorial");  
8.   
9. System.out.println("Protocol: "+url.getProtocol());  
10. System.out.println("Host Name: "+url.getHost());  
11. System.out.println("Port Number: "+url.getPort());  
12. System.out.println("File Name: "+url.getFile());  
13.   
14. }catch(Exception e){System.out.println(e);}  
15. }  
16. }
