String.substring == error

Code:String url = "http://www.google.com";
if(url.substring(0, 7) == "http://") println("Starts with http://"); |

Nothing is printed if you execute the above.
Code:String url = "http://www.google.com";
String http = url.substring(0, 7);
if(url.substring(0, 7) == http) println("Starts with http://"); |

That doesn't work either.

You need to use the equals method on String. Using the '==' operator does an indentity comparison on the objects themselves. Since they're different String objects, it returns false.
So your code should be:
if (url.substring(0, 7).equals("http://"))...
