Get computer name in java

     

We can get the computer name by the java code program. For getting computer name we have used java.net.InetAddress class. We will use static method getLocalHost() for fetching the localhost and after having localhost we will be able to have host name by using getHostName() method of InetAddress class.

Here is the full example code of GetComputerName.java as follows:

 

 

 

GetComputerName.java

import java.util.*;
import java.lang.*;
import java.net.*;

public class GetComputerName
{
  public static void main(String args[]) {
  try{
  String computername=InetAddress.getLocalHost().getHostName();
  System.out.println(computername);
  }catch (Exception e){
  System.out.println("Exception caught ="+e.getMessage());
  }
  }
}

 

Output:

C:\javaexamples>javac GetComputerName.java

C:\javaexamples>java GetComputerName
