Hi there and welcome to the hts forums.
I wanted to post something on the HTS basics section but sadly New post didnt came..
do you mean the basic missions forum? if yes you can use the existing thread for the individual mission and ask your question there.
I have started making applications in Java pretty basic of them but, that is not enough.
Imo Java is a good starting language. you will learn OOP from the very beginning and also learn how to use external libraries pretty early in the process. after that you can go to a language which also deals with low-level stuff (memory management etc) like C.
Im looking for a Mentor here basically and even the most basic guy can help me in my journey..
Consider all of us posting in the forums your mentor! sometimes you might have a question which goes beyond the knowledge of 1 mentor, but the forum will have someone to solve your problem.
As for the start, you can go to the General section of the forum and read one or two of the thousands of posts similar to yours (where do I start, what to learn next, how can I develop myself to be a hacker someday etc).
I think if you do all that you'll learn fast and still have the support you need from all of us in this forum.
