url if else (condition issues) java program

Trying to write a test program, that determines what type of organization is indicated by a web address.

Here's the code so far:

import java.util.Scanner;

public class WebTest
{
    public static void main (String[] args)
    {
    Scanner input = new Scanner(System.in);
    String[] url = {"com", "net", "org", };
    String[] message = {"Business", "Network", "Organization", };
    System.out.println("Please enter a url ending in .com, .net or .org");
    String userinput = input.nextLine();

    if  (url == com )       
    {
        System.out.println("Business");
    }
    else if (url == net )
    {
        System.out.println("Network");
    }
    else if  (url  == org )  
    {      
        System.out.println("Organization");
    }
               else 
        {
            System.out.println("Invalid Input");
                       }

    }
}
