The JavaRush team is in touch, and this is the second digest of our article competition . This collection contains materials that you sent us in just two days - April 30 and May 1. Read, like, comment!
This intriguing name hides the experience of the author (Coldfire, level 17 JavaRush, Moscow) of attending various IT events. Read and be inspired: visiting them is interesting and useful, even for novice developers.
If you've only recently started learning programming, you've probably never heard of Code Coverage. In fact, this term refers to code coverage by tests, and on a normal project it should be, if not one hundred percent, then very close to it. Although, of course, there is code that does not need to be covered... Not very clear? Read and say “thank you” to the author (without quotes). It will be very useful in real work.
A short post about comments in Java is offered by Stepan Uemlyanin (level 23 JavaRush). Do you think the author missed some types of comments in his material? Tell us about it!
Have you not yet felt sincere love and gratitude for our validator? Then be sure to read two articles by Evgeny Grodno (level 34 JavaRush). These materials are very useful, since you are unlikely to find a working Java developer in this world who is not familiar with unit testing and JUnit. Read and learn to cover your code with tests.
Well-commented code means the love and respect of your colleagues. No, really. It’s better for June Valera to write bad code with comments than brilliant code without. After all, the team still has to work with him and the code, but how long Valera will work in this team is unknown. So read the article on commenting in Java, written by Viacheslav (level 3 JavaRush, St. Petersburg). It won’t be superfluous, even if it seems to you that there is nothing like that in the comments.
Another article by Viacheslav. In it, the author talks about another “newbie” complexity - assignment and initialization. Do you feel unsure when you hear the phrase “initialize fields”? Or have you just started studying and don’t really know what we’re talking about yet? Then this material is for you.
Beginners seem to know and understand this very key word... but often not quite... and not completely. If you feel a certain uncertainty about what exactly this does and how to work with it, read the article by Dmitry Denisov (level 29, Yekaterinburg). It will become clearer!
When the new version of IntelliJ Idea 2018.1 was released, we did not fail to tell you about it. However, we missed something, and JavaRush graduate Vladimir (level 40, Almaty) decided to add some additional information to our news.
Have you heard about the Pomodoro technique? If not, we highly recommend trying it. It very often helps developers and other IT specialists increase productivity. It does not require significant preparation and is very easy to perform. Try it too! Moreover, Antoni (level 7 JavaRush, Moscow) wrote an article about Pomodoro with examples of applications that will make working on the technique easier.
(“A thousand inhabitants of hell! I don’t even know what that Markdown is!” - Ed.). If you, like our editor, don’t really know anything about lightweight markup language and what it’s used with, you are welcome to read the material by student Nikita (level 24 JavaRush, Dnepr). With its help, you will not only find out what it is, but also understand how to use it as effectively as possible.
An article with a (presumably) human face in the title was created for all of us by a JavaRush student with the nickname Darth Vader (level 13) from Kharkov. The topic seems to be simple, but it’s like this... it’s often pushed aside until better times, and then there’s no time to deal with it... Just sort out this screening already! Moreover, the person described everything in detail and clearly.
Victor Sergeev, familiar to regular readers from the previous competition, wrote useful material about IDEA hotkeys. Start using them right now. Moreover, Victor wrote not just some kind of complete list, but precisely those keyboard shortcuts that help him work more efficiently.
