Note: I'm not a lawyer but, as I understand it, the version of Java at Oracle's web site is still free to use if you're using it only to practice writing Java code. You can't use it for free to put an application into production. If you want a completely free version of Java, visit jdk.java.net.
In other news: wunderground.com no longer provides free service. Try openweathermap.org/appid instead.
