Learn about string manipulations with StringUtils and Java.
- [Instructor] Apache Commons language…is a library that contains StringUtils.…It supplements the capability of Java string class…and provides methods that are null safe.…You can find information about Apache's Common language…at this URL,…and you can find Javadoc documentation at this URL.…In this video I'd like to illustrate a particular problem…that occurs with certain types of dependencies.…To do this let's go back and press Ctrl+Alt+Shift+S…and remove the dependency for Java Commons language.…
Click apply, click OK…and we'll see that the import statement…can no longer fulfilled.…We anticipate this.…I'll comment that out by pressing Control/…but now, a common technique with an IntelliJ,…when we see a problem,…is to highlight the problem and press Alt+Enter.…This is the type of dependency or dependency problem…that you may encounter frequently.…There are at least two other libraries named StringUtils…that are available via IntelliJ,…but neither one of these are the one that we want to use.…
