Example 1
The following example shows the usage of Java URLConnection getContentEncoding() 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 getContentEncoding(), we're getting the value of content-encoding header field of URLConnection instance 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();
System.out.println(urlConnection.getContentEncoding());
} catch (IOException e) {
e.printStackTrace();
}
}
}
Let us compile and run the above program, this will produce the following result −
Output
null
