Find Your Host Name/IP Address
In this section you will learn about the getLocalHost()
method to print the Host name as well as the IP Address of the local system. For
do for the same we have to call InetAddress class then we need to create a
object, in which we store the local host information.
Find Your Host Name
Here we are going to explore a method to retrieve the
host name of the local system in a very simple example. Here we are just call
the InetAddress class and after made a object of that class we call a getLocalHost() method and pass it in the
Getting list of Local Interfaces on a machine
Here we are going to explain the method to find out the
total no of list of local interfaces available on a machine. Here we are give a
complete example named URLDemo.java.
Getting the Local port
this section you will learn that how a user can access the Local port.
Here we are going to make it easier to
understand the step be step process by the complete example on this topic.
Find the Host name in reverse of given IP address
In this section you will learn to
retrieve the information about the local host name using the getHostName()
method. Here is an example that provides the usage of
the getHostName() method in more detail.
How to retrieve URL information
Here we are going to explain a method for retrieve all
the network information for a given URL. In the given below example we use the
URL class and make a object.
Convert URI to URL
Here we are going to explain the method to change
Uniform Resource Identifier (URI) reference to uniform resource locator (URL). Here we are give a
complete example named "ConvertURItoURL.java".
To retrieve the IP address from Host Name, vice-versa
Here we are going to explain the method to find out the
IP address from host name and to vice verse. Here we are give a
complete example named HostLookup.java. In which we call a InetAddress and make
a object and pass the input value in it.
Construct a DatagramPacket to receive data
In this section we provide a complete code of a example
based on the method DatagramPacket(buffer, buffer.length) for
constructs a DatagramPacket for receiving packets of length length in
more generic way.
Construct a DatagramSocket on an unspecified port
In this section we are going to explain the process to
construct a DatagramPacket object in more generic way. Here we provide a
complete example based on the method for creating the DatagramSocket object
Return the MIME Header
In this section you will learn about the method to
retrieve the MIME header. MIME is stands for Multipurpose Internet Mail
Extensions which is an Internet Standard that extends the format of e-mail to
support. A container for MimeHeader objects, which represent the MIME headers
that is present in a MIME part of data.
Open a URLConnection to specific website address
Here we are going to establish a connection to a
specific web address via a complete example. In the example we create a class
getURLConnection and initialize a variable of url to URL and ucon of
Print the URL of a URLConnection
In this section we are going to describe, how to
retrieve the value of the URL assign to the url object. Here is the complete code
of the program in which first of all we establish a connection then display it.
Getting Image from a URL
This example shows how to get an image from the given URL.
Here we are going to explain
the method to find out the URL information. This program defines the IOException
for the exception handling. This exception is thrown to indicate an I/O problem.
In this section, you will
learn how to get content-length, content- type, and last-modify
date of a file. Here we provide a complete example that uses getHeaderFieldKey()
This is a simple program of
java network and supports the java.net package. Here, we have defined the
class named EncoderTest.java. This class contains static methods for
converting a String to the application-urlencoded MIME format.
In this section, we are
going to explain the method to find out the hostname port number of a local
machine. This program defines the IOException for the exception handling.
Client Socket Information
In this section, you will learn how to get client
socket information. This is a very simple program of java network. Here, we have
used the class named ClientSocketInformation.java that implement the
constructor of the Socket class passing two arguments as hostName
In this section, you will show the used of several
method for different output massage. Here, we
provide a complete example based on the method for creating the Socket() method.
Here, we are going to explore a method to retrieve the
IPAddress of the local system in a very simple example. For do for the same we have
to call InetAddress class then we need to create a object, in which we
store the local host information.
Local Port Scanner
This is a simple program of java network. Here,
we are going to define class named "LocalPortScanner" in which
we use ServerSocket class of java.net package which takes local port number
Low port Scanner
In this section, you will learn how to get local port
number of the local machine. Here, we define the name of program LowPortScanner.
In this we check the argument and create a socket object.
URL Connection Reader
In this section, you will learn about the url
connection reader. Here, first of all we are going to define class named "URLConnectionReader".
After that we make a URL object passing a url "http://www.javajazzup.com"
as string in its constructor.
This is a simple program of java network. In this
section, you will learn how to read HTML file. Here, we create a URL object and pass a url.
After that, we call the URL’s openStream() method to get a
stream from which the contents of the URL can be read.
RMI Client And RMI Server Implementation
The RMI application comprises of the two separate programs, a server and a client. A typical server program
creates some remote objects, makes references to these objects accessible, and
waits for clients to invoke methods on these objects.
