Search - "effective java"
A recruiter called me today. I had to barracade myself in the laundry room to hear him, and still needed to ask him to repeat himself 7-8 times. he spoke at what must have been 15% volume with a super thick Indian accent. He also couldn't pronounce a full third of the terms.
Here's how it went.
recruiter: you full-stack dev? what experience?
me: yes, about 8 years, maybe 10.
recruiter: you know C#?
recruiter: you know java? tomcat? spring?
me: no, I don't know Java.
recruiter: you know react? angular? apache? node?xml? json? html?
me: yes. yes, angular 1. yes, yes, ...
recruiter: ok, i email you java job posting
me: I don't know java.
recruiter: ok, i email you.
Recruiter used "email java job posting." It wasn't very effective.
Recruiter moves quickly! Recruiter used "did you get my email? email" immediately after. It was super effective! @Root becomes angered!
@Root becomes enraged!
recruiter: what [???] [?] [???] [??] java [???] [??] [???] okay
recruiter: You know C#?
me: No, I still don't know C#.
recruiter: ok thank you for time. 😡 *click*
What just happened?
I really don't understand their species.39
Java interested folks.
I recommend reading Effective Java by Joshua Bloch.
It's worth reading.
Even James Gosling praised this book.12
From the book Effective Java, third edition:
"1997, when Java was new, James Gosling (the father of Java), described it as a
“blue collar language” that was “pretty simple” [Gosling97]. At about the same time,
Bjarne Stroustrup (the father of C++) described C++ as a “multi-paradigm language”
that “deliberately differs from languages designed to support a single way of writing
programs” [Stroustrup95]. Stroustrup warned:"
"Much of the relative simplicity of Java is—like for most new languages—
partly an illusion and partly a function of its incompleteness. As time passes,
Java will grow significantly in size and complexity. It will double or triple in
size and grow implementation-dependent extensions or libraries."
Bjarne Stroustrup (the father of C++)6
I believe it is really useful because all of the elements of discipline and perseverance that are required to be effective in the workforce will be tested in one way or another by a higher learning institution. Getting my degree made me little more tolerant of other people and the idea of working with others, it also exposed me to a lot of topics that I was otherwise uninterested and ended up loving. For example, prior to going into uni I was a firm believer that I could and was going to learn all regarding web dev by maaaaaself without the need of a school. I wasn't wrong. And most of you wouldn't be wrong. Buuuuuut what I didn't know is how interesting compiler design was, how systems level development was etc etc. School exposed me to many topics that would have taken me time to get to them otherwise and not just on CS, but on many other fields.
I honestly believe that deciding to NOT go to school and perpetuating the idea that school is not needed in the field of software development ultimately harms our field by making it look like a trade.
Pffft you don't need to pay Johnny his $50dllrs an hour rate! They don't need school to learn that shit! Anyone can do it give him 9.50 and call it a day!<------- that is shit i have heard before.
I also believe that it is funny that people tend to believe that the idea of self learning will put you above and beyond a graduate as if the notion of self learning was sort of a mutually exclusive deal. I mean, congrats on learning about if statements man! I had to spend time out of class self learning discrete math and relearning everything regarding calculus and literally every math topic under the sun(my CS degree was very math oriented) while simultaneously applying those concepts in mathematica, r, python ,Java and cpp as well as making sure our shit lil OS emulation(in C why thank you) worked! Oh and what's that? We have that for next week?
Mind you, I did this while I was already being employed as a web and mobile developer.
Which btw, make sure you don't go to a shit school. ;) it does help in regards to learning the goood shit.7
My C# class loves to come up with weird/unrealistic scenarios to teach a specific language feature... I feel like the more effective way to teach would be to mention a real life scenario where it makes more sense to use the feature and give it some context rather than coming up with some arbitrary series of classes to represent departments and employees and then say "write extension methods for them to write them out"
If you tell me that I'm going to go, ok this works, but is there a specific reason I should do this instead of using a for or foreach to do the exact same thing? Don't get me wrong I see the appeal of extension methods as well as LINQ but this class never gives any sort of context as to why we're doing stuff. This class could be good, I've had classes that focus on language specific features taught in ways that make sense... My Java prof did a great job...
Also all the slides are terribly written...
Like I attached an example of the description for extension methods... The slides then go on to explain how the syntax for them works and gives an example...
Like ok I guess technically you told me what they are and how to use them, but gave zero context...
On the opposite end of the spectrum, I go to MSDN for their definition of extension methods, and it is much more clearly written and gives context to where/why they're used... and this is supposed to be a 5th semester course...2
I hate mostly all of my inability to focus and the fact that I like programming. Surprisingly, they aren't a good match. Im trying to actually learn Java and react native. Anyone have any solutions for quick and effective ways to learn?10
Guy told me Java Swing is more stable and has more effective look than JavaFx. Okay mate, I'm sure. 😒
I've been familiar with C Programming and to sn intermediate level with web design, and currently I'm taking an introductory java Course, And The instructor kinda started with some simple gui apps using swing components on netbeans environment , his claim is that console apps are not that relative in the real word anymore , and gui apps are more interesting for newcomers , and I personally don't think it's a very effective approach , what's your opinion ?4
I once had to implement a program to process CSV files. One line would be one order, so I wrote a class with a static factory method (Java) instead of an ordinary constructor, because I needed to throw exceptions if something with the line was wrong (which now and then was the case: invalid product IDs, missing fields and the like). After I committed my changes (CVS was still common in those days), a coworker (let's call him Max) asked me what the hell I was doing there. He expected me to replace the code (perfectly working, by the way) with either an ordinary constructor or by implementing "the factory pattern properly". His rationale: "We don't have those kinds of things in our code base!" So I let him argue a bit, not finding any well substantiated reason for me to "fix" the code. So Max wanted to team up with another developer in our office (let's call him Rick), explained the "issue" to him. I just sat there and enjoyed, knowing that Rick would not really care. But as soon as Rick understood what I did, he walked over to the book shelf, picked "Effective Java" from it, opened the book at chapter 1 and said to Max: "Look, Josh Bloch suggests doing it exactly that way for the problem at hand!" Max kept on arguing for a while, because his "rationale" (see above) was not affected by the fact that the code was actually good. It just didn't appear in our code base before.
I am still in college and will be going for a job next year. I want to learn Java with all the best practices associated with it. What I would like to do is do a large enough project that would enable me to learn industry standards and use the best practices(effective java etc) in actual code.
So I would ask the devrant community to give some project ideas that would use these practices extensively. I don't know if I am making myself clear here, but any help would be appreciated.9
larry elison laughs the term cloud computing years ago, now offers oracle cloud but failed to come up with an effective strategy, wants to monitize java.
(but still a billionaire though)
Hi dev fellows !
I would like to know what is the best app (nice interface, simple / clean and effective metodology, with lessons / exercices, etc) to learn new langages ? Like python, Java, etc.
I have already Py and Enki which are pretty good.4
