Hey. I'm interested in taking a class in some type of computer programing. I'd like to get certified in order to get a job. After doing some research, it seems like learning HTML5 or CSS3 would be the two more in demand languages. Java is another one that seems popular. Just looking for some suggestions on the path I should take. I'm also interested in creating phone Apps. What is the most common language used for Apps (whether is be for the iPhone or Android)?
