I started learning java and then I want to learn android. What needs the most attention?

Question

Java

I started attending a programming school, like an ordinary person, I cannot master all the information at once. I'm afraid to miss the most important thing. Perhaps you can ask me the question "Why don't you ask your teacher?". The answer is very simple "I want to hear opinions and yours!!!"

Answer 5

Everything is very simple. You need to start learning with examples. If you have already studied another language, try rewriting it in java. Then on android. If not, find a site that offers such examples. There are two categories of such sites - educational, which have theory and examples, and checking, which have tasks and a system to which programs can be sent for verification. There are many such sites, just choose which one you like.
