How to increase the effectiveness of training?

Question

Java

Good afternoon!
At the moment I practice on the Hackerrank website and read G. Schildt at the same time if I have questions about tasks. I have only 2 months of learning Java, but I have already encountered a problem - it seems that I am standing still and not moving anywhere. Does it even make sense to focus so much on algorithms? If you have encountered such a problem, please tell us how you were able to solve it?

Answer 1

Hackerrank makes sense to jack off if you plan on doing coding interviews soon. In the first couple, it is important for you to write a lot of different code. Some kind of pet project or a set of small projects.

"Tell me, Sensei, how to increase the effectiveness of training?" the kouhai asked.
"Stop scribbling stupid questions on the toaster and go study!" Sensei replied.

Old joke.

Answer 3

Good afternoon.
Try to work with different libraries. For example, write a parser using jsoup. Try to write a universal tool for exporting data to xlsx | csv (Apache POI). Explore apache common langs, apache common collections and other common libraries. You can look at lombok.
Come up with ideas for pet projects. For example, a phone book (javafx), a console application (jcommander), etc.
Solving problems on hackerrank is cool and, in principle, you can spend time on them. In particular, Java, SQL, Problem Solving. But as a colleague noted, such sites are needed more for employment.
Try to learn jdbc, work with the database. Here, the site sql-ex.ru solve problems in SQL.
Well, do not stop there, develop further. For example, freelance exchanges helped me to add self-confidence. I have written various simple parsers and bots. As if there is money and it's cool to see the result of your labors.
