Example 1

The following example shows the usage of Java URLConnection getFileNameMap() method. In this example, we're getting an instance of FileNameMap interface using the URLConnection.getFileNameMap() method. Now using FileNameMap instance, we're printing content type of index.htm file name −

package com.tutorialspoint;

import java.net.FileNameMap;
import java.net.URLConnection;

public class UrlConnectionDemo {
   public static void main(String [] args) {
      FileNameMap map = URLConnection.getFileNameMap();
      System.out.println(map.getContentTypeFor("index.htm"));
   }
}

Let us compile and run the above program, this will produce the following result −

Output

text/html

Example 2

The following example shows the usage of Java URLConnection getFileNameMap() method. In this example, we're getting an instance of FileNameMap interface using the URLConnection.getFileNameMap() method. Now using FileNameMap instance, we're printing content type of logo.png file name −

package com.tutorialspoint;

import java.net.FileNameMap;
import java.net.URLConnection;

public class UrlConnectionDemo {
   public static void main(String [] args) {
      FileNameMap map = URLConnection.getFileNameMap();
      System.out.println(map.getContentTypeFor("logo.png"));
   }
}

Let us compile and run the above program, this will produce the following result −

Output

image/png

Example 3

The following example shows the usage of Java URLConnection getFileNameMap() method. In this example, we're getting an instance of FileNameMap interface using the URLConnection.getFileNameMap() method. Now using FileNameMap instance, we're printing content type of architecture.jpg file name −

package com.tutorialspoint;

import java.net.FileNameMap;
import java.net.URLConnection;

public class UrlConnectionDemo {
   public static void main(String [] args) {
      FileNameMap map = URLConnection.getFileNameMap();
      System.out.println(map.getContentTypeFor("architecture.jpg"));
   }
}

Let us compile and run the above program, this will produce the following result −
