How do I use StringUtils in Java?

I'm a beginner in Java. I want to use

but Eclipse outputs
"StringUtils cannot be resolved"

I tried
import java.lang.*;
, but it doesn't work.

java.lang does not contain a class called StringUtils. Several third-party libs do, such as Apache Commons Lang or the Spring framework. Make sure you have the relevant jar in your project classpath and import the correct class.
