How to remove all unused imports from Java file in Eclipse

Here is a couple of ways to remove all unused imports from Java in Eclipse IDE : 1) Go to the line of unused import, press Ctrl + 1 which is an Eclipse shortcut of a quick fix, this will show a drop-down menu to fix this error and one of them would be "remove unused imports" and it will remove that import statement from Java file. 2) Above option is not very efficient if you want to remove multiple unused imports in single click because it removes them one by one. It's better to use the "Organize Imports" feature of Eclipse IDE to remove multiple or all unused imports statement. For using this from Menu, Select Source--> Organize Imports. This will remove all unused imports from that Java file. 3) Third and my preferred option to remove all unused import statement from Java file is ctrl + shift + O, which is a shortcut of Organized import in Eclipse and you can say Eclipse shortcut to remove all unused import statement from Java file. This will also work with the previous option and remove all unused import lines from the source file. Do you want a bonus Eclipse tips? If yes then here you go, you can save all keystrokes required to remove all unused imports from Java source file by using Eclipse save actions, which are actions Eclipse automatically perform when you save Java file. Just check the option of Organized imports in saving action under Window--> Preferences-> Java--> Editor--> Save Actions. This saves heap lot of time while working in Eclipse and one of the reasons I love Eclipse IDE for Java programming. You can also configure formatting and few other actions which will be taken by Eclipse automatically whenever you save your file. One more advantage of using Organize import or shortcut ctrl + shift +O is that it imports all packages which are required by code, So it not only saves time while removing import statement but also helps to import required packages in Java. It means if you copy paste some code and see lots of red line as an error due to non-imported packages, just use this Eclipse shortcut or save your source file if you have configured Eclipse save action to organize import. That's all on Eclipse shortcut of removing all unused import statement from Java source file in Eclipse IDE. It's always good to learn more about IDE on which you are working e.g. Netbeans or Eclipse to improve productivity.
