The article presents Eclipse Key Shortcuts (for Windows) which could be used to perform most common coding tasks in a much efficient/faster and effective manner thereby enhancing overall productivity of the Java developers. Please note there are lot more key shortcuts which could be accessed from Eclipse IDE Windows/Preferences/Keys. However, I have made a mention of only those shortcuts which I found very useful in coding faster. If I missed on any shortcuts keys that you feel would be useful to be added in the list below, please give a shout.
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
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
