Intellij pro tip: double tap the shift key, start typing.

If you have a smaller screen and want to save screen space, turn off tabs

Then use CMD-E for most recent files, CMD+O (Classes) and CMD+SHIFT+O (all files) I forget what double-SHIFT opens files or classes.

The big thing about intellij is making sure to exclude what needs and can be excluded. Otherwise you will be in indexing hell every build. It has gotten better about auto-ignoring build, target and node_modules but sometimes doesn't.

The other thing is when importing a project from existing sources, making sure to select build.gradle or pom.xml and let intellij roll with everything else and setup your default environment.

I just want to give a shout out to the Help Menu -> Productivity Guide in IntelliJ IDEs. It tracks how often you use some of the productivity features of the IDE and what you haven't used.

Vim and emacs are both good text editors, and can be used to write source code in a pinch. Just like a rock can be used as a hammer.

To the surprise of no one, Oracle took a left turn at the last minute and added to their ToS that OracleJDK 11 can't be used for commercial purposes without a license.

https://blog.joda.org/2018/09/do-not-fall-into-oracles-java-11-trap.html

So those of you moving to Java 11, use OpenJDK or Zulu.

CTRL+O and CTRL+SHIFT+O are basically the only chords I use in intellij

for awhile I used... what is is, CTRL+B for go to definition? CTRL+D? But I end up just right clicking and using the gui more often.

Been using QT Creator lately and that IDE does not have tabs. You have a dropdown to switch between opened documents (and a list view if you want, and ctrl+tab if you're so inclined). I miss tabs. Tabs are good. I can live without them, but I'd rather have them. It is among my few complaints about an otherwise pretty great IDE.

I like the way IntelliJ handles it - ctrl+tab is basically your tab history (like ctrl+e except it switches as soon as you release ctrl, so one press will toggle back to the last tab), there's back navigation, and there's a bunch of fast search options if you need to go to something you haven't touched in a while. No need to janitor a tab bar or keep track of where the last things you were working on are located on the bar, it was honestly refreshing when I took the plunge

I guess that doesn't work if you want a specific consistent setup with certain tabs in place, so they're always there no matter how long it's been since you used them, but you can probably do something with favourites or whatever. Pin them to the switcher popup, something like that

Whatever works for you, y'know, but I'd definitely encourage people to try ditching them for a while at least!

Thanks for prodding me to look up tab switching in Intellij, alt-arrrows moves between open tabs, going to use that a lot. One particular touchpad gesture is also very useful, three finger side swipe to swap between current window and most recently used one, which is very useful for quickly *ahem* researching things on stack overflow for instance.

e: Related thing, touchpad scroll hasn't worked for a while. Suddenly it worked, now it's not working anymore. That is, works fine elsewhere but not in Intellij. And ideas? I'm on Windows 10 btw.

I don't even look at tabs anymore. Cmd+Shift+N is 99% of my navigation in Intellij.

I like this series, although I haven't read the Java one: https://www.amazon.com/Head-First-Java-Brain-Friendly-Guide-ebook-dp-B009KCUX3S/dp/B009KCUX3S/ref=mt_kindle?_encoding=UTF8

Very clear, simple, hand hold-y pedagogical stuff. Get it on Kindle, so you can have it on the desktop Kindle app along with a Java IDE on a fully charged laptop. https://www.jetbrains.com/idea/ Make sure everything runs and you can do "hello world" before you fly, it should be a productive couple of hours.

I have Core Java by Cay Horstmann which is written for people already familiar with programming, though not necessarily OOP so it does go over those concepts again. It also has lots of notes throughout as to how Java differs from C++ if that's helpful.

There are two volumes (Fundamentals and Advanced Features) and they are quite big but most of it is code examples that can be skimmed. He also has a version which apparently combines the two volumes into a condensed version called Core Java for the Impatient, though I don't know if that's any good.

I used this book (among some other sources) to teach myself java and now I am employed as a java developer.
It is good for people like me with a short attention span and not that experienced as a programmer.

It's old Java, like Java 5.0. Some of the refactoring is also a bit questionable. However, like another poster here, I got started with that book and I had a short attention span. It is an amazing start.

I actually bought that humble bundle to check out some of their newer books to see if they've kept the "moxie" (not quality) which can maybe help my distracted friends to start programming.

On that note, the books from Humble bundle come in mobi, epub, and pdf format. I personally think the Head First series is best enjoyed as PDF format as it's a very graphical teaching approach.

The MUMPSorceress: Jan 6, 2012; ^SHTPSTS; Gary’s Answer

We have a library that we use for a lot of stuff, and at the moment it involves a painful amount of nearly identical boilerplate be written for each new job we write. It can be as much as 200 lines for a reasonably complex job.

Unfortunately it can't be abstracted away via interfaces or abstract classes because we can have a variable number of fields internal to the class (each of either a type Foo<T> or String) and we have to write this boilerplate code for each field. It's the exact same code with the field name swapped out basically which got me thinking that maybe there was a way to do add code generation for these things with an annotation.

For example, right now we do something like

Java code:

Foo<T> stuff = null;
Foo<T> junk = null;

String pile = null;

//just gonna list names since implementation ain't important

public void setStuff;
public Foo<T> getStuff;
public Bar<Foo<T>> getSpecialStuff;

//repeat for junk

public String getPile;
public void setPile;
public void doStuffWithPile;

public Collection<Foo<T>> getAllFoos;
public Collection<String> getAllStrings;

All of these functions will be 100% identical except for the field being operated on. I'd love to be able to write this:

Java code:

@foo
Foo<T> stuff;
@foo
Foo<T> junk;
@fooString
String pile;

and just have all the repetitive stuff generated behind the scenes.

I've been googling documentation on annotations and I'm not clear if this is possible. None of these functions have to be used internal to the class, which just works with raw fields. These functions can be called by the superclass at runtime or by other classes. Can anyone point me toward some useful docs or shoot this idea down before I waste too much time? Thanks!
