  • Last Updated : 02 Jan, 2019

The getHost() function is a part of URI class. The function getHost() returns the host of a specified URI.
The Host part of the URL is the host name of the URI.

Function Signature:

public String getHost()

Return Type The function returns String Type

Syntax

url.getHost()

Parameter: This function does not require any parameter



The following programs will illustrate the use of getHost() function

Example 1:




// Java program to show the 
// use of the function getHost()
  
import java.net.*;
class Solution {
public static void main(String args[])
    {
        // URI  object
        URI uri = null;
  
        try {
            // create a URI
            uri = new URI("https://www.geeksforgeeks.org");
  
            // get the Host
            String host = uri.getHost();
  
            // display the URI
            System.out.println("URI = " + uri);
  
            // display the Host
            System.out.println("Host = " + host);
        }
        // if any error occurs
        catch (URISyntaxException e) {
            // display the error
            System.out.println("URI Exception =" + e.getMessage());
        }
    }
}
Output:
URI = https://www.geeksforgeeks.org
Host = www.geeksforgeeks.org

Example 2: The difference between getAuthority() and getHost() function is that getAuthority() returns the host along with the port but getHost() returns only the host name.




// Java program to show the 
// use of the function getHost()
  
import java.net.*;
  
class Solution {
    public static void main(String args[])
    {
        // url  object
        URI uri = null;
  
        try {
            // create a URI
            uri = new URI("https://www.geeksforgeeks.org:80");
  
            // get the Authority
            String authority = uri.getAuthority();
  
            // get the Host
            String host = uri.getHost();
  
            // display the URI
            System.out.println("URI = " + uri);
  
            // display the Authority
            System.out.println("Authority = " + authority);
  
            // display the Host
            System.out.println("Host = " + host);
        }
        // if any error occurs
        catch (URISyntaxException e) {
            // display the error
            System.out.println("URI Exception =" + e.getMessage());
        }
    }
}
Output:
URI = https://www.geeksforgeeks.org:80
Authority = www.geeksforgeeks.org:80
Host = www.geeksforgeeks.org
