In this article, we will discuss how to remove unused imports in Eclipse IDE
1. To remove unused imports in Eclipse IDE:
This is basically called Organize imports in Eclipse IDE. There are 2 ways; we can organize imports i.e.; removing unused imports
- Click Source menu –> Organize Imports
- Using short-cut keys CTRL + SHIFT + O
1.1 Organize Imports from Source menu
Few unused imports in the below Java class
Click Source Menu –> Organize Imports
After organizing unused imports
1.2 Click CTRL + SHIFT + O simultaneously
Few unused imports in the below Java class
Click CTRL + SHIFT + O
Q) When it is required ?
- Initially, we thought ArrayList fits our logic to store group of similar values
- And we started using ArrayList through-out in our program with “java.util.ArrayList” import statement right at the top of the Java class
- But suddenly, logic changed to use HashSet instead of ArrayList for maintaining uniqueness inside Collection
- And we started changing ArrayList to HashSet in our program
- During these times, we would never give a look into unused imports
- So, therefore it is better advised using this shortcut to remove unused import statement
