Example 1

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

package com.tutorialspoint;

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

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

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

Output

Example 2

The following example shows the usage of Java URL toURI() 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 getURI() method, we're getting the URI representation of the URL object and printing the same −

package com.tutorialspoint;

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

import java.net.URISyntaxException;

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

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

Output

http://www.tutorialspoint.com:80/index.htm

Example 3

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

package com.tutorialspoint;

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

import java.net.URISyntaxException;

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

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