Where can I practice C++ and Java programming?

Question

Java

I'm learning Java (recently started) and C++ (1.5 years), but I can't find good practical (no olympiad) problems or examples of practical problems, but rather a book with tasks and code execution options. Also, by practical tasks, I mean creating a graphical interface with network protocols, working with the mouse and keyboard, etc.

Answer 1

I am not a fan of A. Lebedev, but sometimes he says the right things. For example, about "Will you send me a test task?" He says - "and think of it yourself!" So it is with tasks in general. You need to see the issue. More precisely, to see how, with the help of programming, you can move a problem from some unresolved state to a solved one. In life, the task will never tell you that "here I am, the task" and will voluntarily give up its solution.
When I was doing athletics, I thought that there are two states, one when I train, and the second when I perform. The coach explained to me that there is only one condition - training. Only at competitions you give all the best. This has completely changed my attitude towards task search.
If you think you can solve a problem, aren't you capable of inventing it? Each task is a test of one's capabilities, a challenge. If you are not working on solving the problem in this way, then you are doing and working incorrectly, because. no development.

Answer 3

Concerning with ++
On naked c ++ you will not go far. You also need to know libraries.
I recommend qt as a combine of everything that may be needed in everyday development
Book Qt 5.3. Professional programming in C ++ (the book is not a fountain, but I don’t know any alternatives for qt5 +)

Answer 5

Take your old texts and sort them out. as if rewritten now. is everything clear. how to write so that everything is clear at a glance. rewrite them.
-take the text of the library you are using. study part. rewrite analog.
- read texts good and bad. what would you like to change? what you liked.
- write a simple sql database
- write a console game quest.
- study tdd, solid
- analyze your texts, try to highlight parts that can be reused. rewrite them.
