How do I add class javadoc in intellij - intellij-idea

I am using Intellij IDEA.
I know how to work "fix doc commnet"
It's always using method.
My question~
I would like to add javadoc on Class.
How can I do it?

There's nothing special, just place the cursor above the class and type:
/**
and press enter.

Before each class you want documentation for, insert /** and press enter. A javadoc block should be generated for you. If you want to go ahead and generate the javadoc, do Tools -> Generate Javadoc and add whatever configuration options you feel necessary.

Intellij - Missing basic intention actions

I have absolutely no idea why IntelliJ IDEA 2022.1.1 (Community Edition), just after creating a new Java class and typing in some random fields, doesn't show basic intention actions like generate constructor, getter, setter etc.
I know it looks so trivial - despite I'm Java beginner and IntelliJ IDEA's newbie this thing occurs for first time:
class Product {
String product;
double price;
}
It looks like you are using the wrong shortcut (Show Intention Actions or Alt+Enter instead of Generate or Alt+Insert).
See the documentation.

Intellisense - deduce right Class by its methods

I'm used to work with NetBeans and now I'm trying IntelliJ. So my question is: Does IntelliJ has a way to get right class by its methods?
For example, in NetBeans if I write:
glGenBu // Intellisense will kick in and will suggest me
to use GL15.glGenBuffers() method from GL15 class
This will automatically import the right library.
This is very handy because I'm working with LWJGL and it has a bad way to manage OpenGL methods ('GLXX' where XX is the version of OpenGL and all methods that appeared in that version are stored in that class) and I never remember the right class where my desired method is.
Thank you.
Pressing Ctrl+Space when you already see completion list will show more suggestions, with static methods from the entire project among them. See https://www.jetbrains.com/help/idea/auto-completing-code.html for more details.

IntelliJ - Cucumber step definition case

Ever since I upgraded to latest community edition of IntelliJ 15.0.3, whenever I auto generate a step definition from the feature definition file using alt + enter, it creates the method in camel case rather than usual style with underscores.
For e.g. it used to be generated like this
#When("Cucumber is awesome")
public void cucumber_is_awesome() {}
But now it generates in usual camelCase convention:
#When("Cucumber is awesome")
public void cucumberIsAwesome() {}
Is there any way to change this setting back to the first style?
Thanks
What you can do is check the
Run -> Edit Configuration
then go to the cucumber config. Within the Program Arguments check if
--snippets camelcase
is present and take it out. that should make it show it in snake casing again. Hope that helps :-)

Modify a view in RCP

In eclipse have a function that when I'm modifying a class that will implements a * in the title like this:
And when I select Save button that * is no more.
The question is I want add that function into my application but have no idea or any key word to search it on google. Any suggestion?
Implement IEditorPart interface in your own editor and override its isDirty() and doSave() methods. Send notifications about content changes to workbench with firePropertyChange() (with PROP_DIRTY argument).
Don't forget to contribute your editor to org.eclipse.ui.editors extension point.

How to add a new method in Smalltalk source code?

I am new to Smalltalk and I am trying to add a new method in the Integer class present in Smalltalk. The method should go in the 'accessor' protocol. I am using VisualWorks and not finding any option to do that. I have gone through the developers guide still its not clear to me. Can someone please give me screen shots or step wise solution about how to proceed with it?
Open your browser window [Small Talk Launcher --> System --> Browser]
Select a Package
Select a Class
Select a Protocol to which you want to add your new method.
You can find the tab "source" below the 4 partitions [Package, Class, Protocol, Method].
Replace the text in that "source" tab with the source code of your method.
Go to to "edit" option in the Browser menu.
Select "Accept" option.
Your new method is added successfully!
Cheers!
Aditya.
If you go into Smalltalk idea, you'll de that classes are objects as well and that you can just say class to compile a new method e.i. add a new method to itself:
Integer compile: 'getSomeVar ^someVar' classified: 'someVar'
_This will add to Integer in someVar protocol a method called getSomeVar that will return someVarinstance variable._
But for a general workflow you should use tools provided by Smalltalk environment such as a System Browser mentioned by Aditya Kappagantula
