Example 1

The following example shows the usage of Java URL getPort() method for a valid url with https protocol. In this example, we're creating an instance of URL class. Now using getPort() method, we're getting the port and printing the same −

package com.tutorialspoint;

import java.io.IOException;
import java.net.URL;

public class UrlDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("https","www.tutorialspoint.com","/index.htm");
         int result = url.getPort();
         System.out.println(result);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

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

Output

-1

Example 2

The following example shows the usage of Java URL getPort() method for a valid url with http protocol. In this example, we're creating an instance of URL class with a port number as 80. Now using getPort() method, we're getting the port and printing the same −

package com.tutorialspoint;

import java.io.IOException;
import java.net.URL;

public class UrlDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("http","www.tutorialspoint.com",80,"/index.htm");
         int result = url.getPort();
         System.out.println(result);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

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

Output

80

Example 3

The following example shows the usage of Java URL getPort() method for a valid url with file protocol. In this example, we're creating an instance of URL class. Now using getPort() method, we're getting the port and printing the same −

package com.tutorialspoint;

import java.io.IOException;
import java.net.URL;

public class UrlDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("file","www.tutorialspoint.com","/index.htm");
         int result = url.getPort();
         System.out.println(result);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

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

Output

-1
