Is it possible to assign a shortcut to go automatically on New Java Class Dialog? At the very beginning of a project when I am creating a lot of classes, it's quite annoying have to go through the 'New..' wizard.
Here's the image of the dialog I want to reach.
Select Window -> Preferences -> General -> Keys and search for New (Class). Click on Binding, press the keyboard shortcut you want, and click OK to configure the shortcut.
Press alt+shift+n it will give you a context menu from where you can select new class,package,interface
Ctrl+n will launch new wizard, there you can select the class/any to create new document.
There's an icon (C icon) in the header toolbar for creating class! Its available by default Just click it!
hit alt+shift+N and then click the respective first character for creating
the respective file. For example, let's suppose you want to create a new java class:
Hit alt+shift+N.
Hit c (stands for creating java class).
j (it will highlight the java package).
like this you can use shortcut keys as well as first character of the word what you want to create.
Hope this might help.
You could use Ctrl+3 to open the "Quick Access" Wizard and type in "java class"
on Mac alt(option)+command+N > displays a menu, scroll using arrow keys for appropriate selection and hit Enter.
You can use the New Java Class wizard to create a Java class. It can be invoked in different ways:
By clicking on the File menu and selecting New → Class.
By right clicking in the package explorer and selecting New → Class.
By clicking on the class drop down button and selecting class.
The shortcuts for basic Eclipse file management actions are different between Mac and Windows/Linux environment.

First press
ctrl + n and then press c
then press Enter
press ctrl + n
press c (for selecting the class)
press Enter (for creating a class name)
and then class will easily created.

I am more familiar in Eclipse and need the IntelliJ equivalent. In Eclipse, I could open a java class, right click, show file in package explorer and it would highlight the file on the left. What is the IntelliJ equivalent.
You can highlight a file you have open in the editor in a number of views using the Select In...menu that can be opened using ALT-F1 when the editor window has the cursor.
The most usual ones (Project/Packages) are found under the menu opened by ALT-F1 and then right arrow.
You can also double click the circle/cross button ontop of the Project view
it will show you the current active file in the project structure
You can turn on Autoscroll from source in Project Tool Window so that the file/class to the left is scrolled to as soon as you open a file for edit.
If this option is on, IntelliJ IDEA automatically navigates from a file in the editor to the corresponding node (file, class, field, method, etc.) in the Project tool window.
Note that selecting this option makes the Scroll to Source button unavailable.
It is called "select in project view".
You'd better edit your keymap ! (alt+F1 right arrow is not very efficient...)
file > settings > keymap > select in project view : alt+E for example
You can press Alt-Home, it goes to the navigation bar.
Go to or select the package by pressing left arrow.
Press F4 now to see it in the project view.
I would hold down Ctrl and Click on the name of the class in my build path to navigate to that Class.
Please help me in finding the keyboard shortcut without using the mouse click.
Keyboard shortcut to navigate into classes (or variable declarations) is F3.
See this article for more useful shortcuts (or just google for another page about eclipse shortcuts)
When hovering over a variable, one can go straight to its definition pressing F3. But what I'm looking for is for a way to go directly to its type definition, which I'm currently doing by pressing CTRL + clicking "Open declared type".
Is there a easier way to do this?
Assign a key stroke for 'Navigate > Open Hyperlink' command via 'Preferences > Keys'. (I use F6)
Now you can use this key stroke instead of using Ctrl+Click to bring up the hyperlink popup.
Not exactly what you are looking for, but this is the best solution I think.
There is another option, using Ctrl+Shift+t. This opens a window where you can look up any type you wish. This becomes a shortcut when you highlight your target, press Ctrl+Shift+t and hit enter. Imho Ctrl+Click is still faster.
If you would like to check any other shortcuts bind keys go to Windows -> Preferences -> General -> Keys
I've always relied on a combination of ctrl+shift+t and the hover options. I never thought of the key stroke assignment. I might try mapping a scroll button click, like opening a link in a new tab.
in Windows > Preferences > Keys
search for Go to Type and assign it a ctrl-f3 or shift-f3 (there is a conflict with ctrl-f3)
I know I can just grep it, but I was wondering if Eclipse has a built in feature where I can highlight a public class member and get a list of all the places where it is being used in the package.
TIA
Yep, right click on the member (I usually left click first and wait for Eclipse to highlight the member to make sure it knows what I want to search for) and choose Open Call Hierarchy for methods or References > Workspace for fields.
Highlight the class member and press ctrl + shift + g to find references in the workspace
Click Group by Package in the toolbar:
Click the View Menu arrow icon in the toolbar and select Show as Tree in the popup menu
Locate the desired package in the treeview and expand it to see results
I don't use Eclipse for Java, but in CDT, you can right click and select References->Project to do this.
How do you switch between header (.h) and implementation files (.cpp) in Eclipse when using the C++/CDT environment with a keyboard shortcut?
In XCode you can quickly switch between headers and implementation with applekey option and up/down arrow keys. I was hoping that eclipse had something similar, but I haven't found it yet.
Ctrl + Tab.
See in menu Window --> Preferences --> "General" category (far left) --> Keys --> "Toggle Source/Header"
Ctrl + Tab is the default shortcut and here is a list of some of the more useful shortcut keys in Eclipse.
Ctrl + Tab is the default shortcut. You can change it in Window->Preferences->General->Keys - Toggle Source/Header
F3 to jump between declarations and definitions of specific methods
This is another good one to know in this context:
double click on the method name with the mouse, selecting it
hit F3 (shortcut for Right Click > Open Declaration)
This takes you from the declaration (.hpp) to definition (.cpp) and vice versa depending on which one you are currently in, which is useful if you want to go to the other file to see a specific method when the file is large.
Tested in Eclipse CDT 2019-09.
You can also Ctrl + click on an identifier ( method name of member,... ). That way you seldomly need Ctrl + Tab.
