I am so Lost. just wondering should i learn java as a beginner Programming Language.

@Awais: You can do it! I started with JAVA for my computer science coursework. I agree with Jeremy Hill that it is a good idea to supplement what you're learning here with material from other sources. These courses do tend to move fast, but in my experience it's because they are trying to cover the form/syntax of the language before diving deep into the logic behind it. This particular block is covering some of the more complicated aspects of classes and methods that were really hard for me (and still can be sometimes).

If you are feeling like it's too much, you could always start with Python. I found that the simplicity of the Python language regarding declarations, functions, array etc... made it much easier for me to transfer into other languages. There is a great book by No Starch Press called "Automate the Boring Stuff with Python" that is a great guide when used in conjunction with Treehouse.

Most importantly is not to give up. You're smart and hard working, that's why you're here. We're all here to help you if you need anything and we're all still learning (you never really feel like you know it all; you just learn to use what you need to when you need it).

Good luck!
