How to ?check whether PC is connected to Internet programmatically using java program

Hello Everyone! Today in this video I am going to step by step guide you How To check our PC having an internet connection or not using simple Java code. If you want to ping a particular URL or website, then you first need to check if an internet connection available on your PC.

Checking Internet connectivity using Java can be done using 2 methods:
1) by using getRuntime() method of java Runtime class.
2) by using methods of java URL and URLConnection classes.

Java Runtime Class:This class is used to interact with java runtime environment (Java virtual machine) in which the application is running. It provides methods/functions to execute a process or a command, invoke garbage collector, get total and free memory in the JVM etc.

getRuntime():This method of java runtime class returns the runtime object associated with the current java application

Java URL Class:This class provides methods that returns various information like protocol, hostname, file Name, port Number etc of the URL.

Java URLConnection class:It represents a link between URL and application and can be used to read and write data to the specified resource referred by the URL

openConnection():This method of java URLConnection class opens the connection to the specified URL.
METHOD 1:
Output by this method will be 0 if the internet is connected and it will be 1 if the internet is not connected.
