Top 30 Eclipse Keyboard Shortcuts for Java Programmer


This tutorial is about 30 Eclipse keyboard shortcuts, this list is by no means complete and I will suggest you guys to share eclipse shortcuts listed other than here to make this more useful. Eclipse is the most used Java development IDE and knowing Eclipse shortcuts not only improve your productivity but also makes you more efficient. You will have more time for things you like to do. Using keyboard shortcuts also helps to impress colleagues and shows that you have a good hold on tools you used for Java Development. If you are a Java developer, who use Eclipse as its main IDE for all coding, development, and debugging purpose, then I also suggest you to take a look at The Java Developer's Guide to Eclipse, 2nd Edition, one of the best book to learn how to use Eclipse from Java programmer's perspective.
I was big fan of Netbeans IDE before coming across Eclipse because I was from J2ME background and Netbeans provide sophisticated IDE environment to enable you to build, debug and run your Java application in various emulator including some advanced processing options e.g. preprocessing, setting up Exception breakpoint etc. From that time I love to know keyboard shortcuts on IDE and other tools, I used for development including Edit Plus, Microsoft Excel etc.
But when I join an investment bank I came across Eclipse IDE, since everybody in my team is using and Netbeans IDE was not available in company (don’t know why that was not allowed net-beans even though it was free) I have decided to go Eclipse way, later I found that Eclipse was most suited for that application given some of cool feature of eclipse e. g. Remote Debugging, Conditional Breakpoints, Exception breakpoints and Ctrl+T and Ctrl+R kind of shortcuts.
Here I am sharing a list of 30 Eclipse keyboard shortcuts which I found most useful and using in my day to day life while writing code, reading the code or debugging Java application in Eclipse.

30 Useful Eclipse Keyboard Shortcuts for Java Programmers

2     Ctrl + Shift + R for finding any resource (file) including config xml files
This is similar to above Eclipse shortcut with only difference that it can find out not only Java files but any files including XML, configs, and many others, but this eclipse shortcut only finds files from your workspace and doesn’t dig at jar level.
