There were some useful feedbacks on reddit post from where I took some commands and
added to the list below. Thanks for the shout.
Java developers’ productivity when working with Eclipse IDE could be
increased to a great extent if he/she should be work in a faster and effective
manner in following broad areas of work:
- Working with Classes/Interfaces
- Working with Tabs
- Quick reference/help documentation
- Common text editor commands
Following describes specifics on all of the above areas along with the
Shortcuts Keys commands.
Working with Java Classes/Interfaces (Resources)
Many a times, we need to following while coding:
- Open any specific Java classes/interface
- Open structure of specific Java classes/interface and navigate
through member methods and variables
- Create getter/setter methods
- Work with errors and apply quick fixes
- Go to declaration of any specific classes/interface from within the
code
- Search the Java classes/interfaces across the packages for specific
texts etc.
Following are the commands:
- Helpful commands for coding Java classes/interfaces &
resources files
- CTRL + Shift + R: Open a dialog box where one could write initials of
Java classes/interfaces and other resource files such as XML etc and, the
list would appear showing all the matches. One could also do quick search
using * and ?.
- F3: Open classes/interfaces decleration
- CTRL + F3: Show the structure of the selected element including
methods and member variables. It helps to quickly navigate the methods or
variables.
- CTRL + Shift + Down: Go to Next Member. The same could be achieved
using CTRL + F3 and using down arrow.
- CTRL + Shift + Up: Go to Previous Member. The same could be
achieved using CTRL + F3 and using up arrow.
- F4: Open a type hierarchy on the selected element. Shows member
variables and methods of the selected element.
- CTRL + Shift + F: Format the block of code including class and its
methods.
- CTRL + D: Delete selected line(s)
- ALT + Shift + R: Rename the classes. Useful for code refactoring.
- CTRL + 7: Comment the select block of code. Pretty useful.
- ALT + Shift + S then H: Generate equals and hashcode method.
- Helpful commands for handling errors
- CTRL + .: Go to next error
- CTRL + ,: Go to previous error
- CTRL + 1: Show quick fixes
- Helpful command for getter/setter methods
- CTRL + 1: As you define the member variable, you could place the cursor
on the variable and press CTRL + 1. It would show up options where you could
select “Create getter and setter for…”.
- ALT + Shift + S then R: This is formally suggested by Eclipse for
creating getter and setter methods.
- Helpful commands for search
- CTRL + H: Open Search Dialog which could be used to search Java
classes/interfaces consisting of specific text related with type, methods,
member variables, package etc.
Working with Tabs
Often, we need to do following with the tabs:
- Move between the tabs consisting of source code for different Java
classes
- Close the tabs, one at a time or all of them at once
- Maximize/minimize the tab for ease of development
Following are the shortcut keys which helps to achieve above objectives
faster than the mouse:
- CTRL + F6: Next Tab/Editor
- CTRL + M: Maximize Activity Window
- CTRL + W: Close Tab/Window
- CTRL + Shift + W: Close all Tabs/Windows
Quick Reference/Help
Following command would help in opening associated JavaDoc right in the
Eclipse IDE. All you need to do is place your cursor on the element and press
the following keys:
- Shift + F2: Open Attached Javadoc
Common Text Editor Commands
Following are some commonly used text commands which could speed up coding,
in general.
Add New Lines
- CTRL + Shift + Enter Insert line above Current Line
- Shift + Enter Insert Line below Current Line
Collapse/Expand All Methods
- CTRL + Shift + Numpad_Divide Collapse all methods
- CTRL + Shift + Numpad_Multiply Expand all methods
