how to import multiple packages in one java file?

Question

How can I import multiple packages in one java file. For example if I created a main method in one java file and packages in different. I want to import 3 packages in one line then how can I import all in one line?

Answer 1

In Java, you can import entire package using * . to import multiple packages. eg import com.package1.*; to import everything from package1. To import multiple packages, eg import com.package1.*; import com.package2.*; import com.package3.*; import com.package1.*; import com.package2.*; import com.package3.*;

Importing on a single line like import package1.*,package2.*,package3.*; is not possible in java but you can import entire directory if the packages are in the same directory as in import com.*;

Answer 2

The wildcard * can import everything from a single package:

import junit.*;

Just be sure you don't clutter your local namespace with classes you are not using. If you're using a Java IDE, consider using the Organize Imports feature (ctrl-shift-o in Eclipse) instead.
