simulating PING command

Aim:

To Write the java program for simulating ping command

Algorithm

Step 1: start the program.

Step 2: Include necessary package in java.

Step 3: To create a process object p to implement the ping command.

Step 4: declare one BufferedReader stream class object.

Step 5: Get thedetails of the server

5.1: length of the IP address.

5.2: time required to get the details.

5.3: send packets , receive packets and lost packets.

5.4: minimum ,maximum and average times.

Step 6: print the results.

Step 7:Stop the program.

Program:

import java.io.*;

import java.net.*;

class pingserver

{

public static void main(String args[])

{

try

{

String str;

System.out.print(" Enter the IP Address to be Ping : ");

BufferedReader buf1=new BufferedReader(new

InputStreamReader(System.in));

String ip=buf1.readLine();

Runtime H=Runtime.getRuntime();

Process p=H.exec("ping " + ip);

InputStream in=p.getInputStream();

BufferedReader buf2=new BufferedReader(new

InputStreamReader(in));

while((str=buf2.readLine())!=null)

{

System.out.println(" " + str);

}

}

catch(Exception e)

{

System.out.println(e.getMessage());

}

}

}

Output:

Enter the IP address to the ping:192.168.0.1
