Brendon’s Answer

Start with the basics (can not be emphasized enough). After you have mastered the basics, then figure out what kind of development work you would like to do, be it web development, build mobile apps etc. Also find out what type of Developer you would like to be Full-Stack or just specialize.

Kumar’s Answer

Focus on learning data structure and algorithms . Implementing algorithm in Java or Python would become a lot easier if you are aware of core data structures. Go through the Programming Language's documentation to look for APIs for your code. If you know the code concepts, and how a language works it would be easy to figure out what you need and where to look for. To be honest, even a programming language grows and it's not easy to remember all the APIs. Focus on Java's core concepts, Python's core concepts, data structures, algorithms and specific areas based on your problem statement and those should help you.

Mickael’s Answer

Hi Xiaohui.


Python and Java are two languages but not the only one used in computer programs. If you want to learn them, I would start first with Python.
There are plenty of tutorials in Python ion the web (just search "Python tutorial" in your search engine).
And there are online Python interpreters so you do not need to download and install anything. That's probably the easiest option.
Then, like any language, you need to practice. Just practice a lot.

Eleanor’s Answer

Hi Xiaohiu! There are a multitude of programming languages available to learn. So first step would be to determine what kind of computer programming you want to do (ie. what problems do you want to solve) and then determine which language you need to learn to accomplish that. There is a series of books that are great desktop references available on Amazon. Since you specifically asked about Java and Python, here's links to the "In a Nutshell" books for those two languages:
