Java - URLConnection getHeaderFieldInt(String name, int Default)
Description
The Java URLConnection getHeaderFieldInt(String name, int Default) method returns the value of the named field parsed as int.
Declaration
Following is the declaration for java.net.URLConnection.getHeaderFieldInt(String name, int Default) method
public int getHeaderFieldInt(String name, int Default)
Parameters
name − the name of a header field.
Default − a default value.
Return Value
the value of the field, parsed as an integer. The value of the Default argument is returned if the field is missing or malformed.
Exception
NA
Example 1
The following example shows the usage of Java URLConnection getHeaderFieldInt(String name, int Default) method for a valid url with https protocol. In this example, we're creating an instance of URL class. Using url.openConnection() method, we're getting the URLConnection instance. Using getHeaderFieldInt(String name, int Default), we're getting the value of an header field identified by name Expires and printing the same −
package com.tutorialspoint; import java.io.IOException; import java.net.URL; import java.net.URLConnection; public class UrlConnectionDemo { public static void main(String [] args) { try { URL url = new URL("https://www.tutorialspoint.com"); URLConnection urlConnection = url.openConnection(); int headerValue = urlConnection.getHeaderFieldInt("Content-Length",1); System.out.println("Content-Length: " + headerValue); } catch (IOException e) { e.printStackTrace(); } } }
Let us compile and run the above program, this will produce the following result −
Output
Content-Length: 293827
Example 2
The following example shows the usage of Java URLConnection getHeaderFieldInt(String name, int Default) method for a valid url with http protocol. In this example, we're creating an instance of URL class. Using url.openConnection() method, we're getting the URLConnection instance. Using getHeaderFieldInt(String name, int Default), we're getting the value of an header field identified by name Date and printing the same −
package com.tutorialspoint; import java.io.IOException; import java.net.URL; import java.net.URLConnection; public class UrlConnectionDemo { public static void main(String [] args) { try { URL url = new URL("http://www.tutorialspoint.com"); URLConnection urlConnection = url.openConnection(); int headerValue = urlConnection.getHeaderFieldInt("Content-Length",1); System.out.println("Content-Length: " + headerValue); } catch (IOException e) { e.printStackTrace(); } } }
Let us compile and run the above program, this will produce the following result −
Output
Content-Length: 0
Example 3
The following example shows the usage of Java URLConnection getHeaderFieldInt(String name, int Default) method for a valid url with http protocol. In this example, we're creating an instance of URL class. Using url.openConnection() method, we're getting the URLConnection instance. Using getHeaderFieldInt(String name, int Default), we're getting the value of an header field identified by name Expires and printing the same −
package com.tutorialspoint; import java.io.IOException; import java.net.URL; import java.net.URLConnection; public class UrlConnectionDemo { public static void main(String [] args) { try { URL url = new URL("http://www.google.com"); URLConnection urlConnection = url.openConnection(); int headerValue = urlConnection.getHeaderFieldInt("Content-Length",1); System.out.println("Content-Length: " + headerValue); } catch (IOException e) { e.printStackTrace(); } } }
Let us compile and run the above program, this will produce the following result −
Output
