StringUtils.isEmpty

[Premila Devi Dayalan]

Dear All,

Please define the meaning of

StringUtils.isEmpty

,are they define as

checks if a String contains text

Sample Code:
(!StringUtils.isEmpty(asset.getSerialNumber()))

[Jesper de Jong]

Note that the class StringUtils is not a class from the standard Java API. It's probably a class from some library, or even defined in your own software.

Most likely it checks if the string that you pass in is null or "". It's just a convenience method, so that you don't have to write code like this all the time:

if (!(asset.getSerialNumber() == null || asset.getSerialNumber().equals("")))

Noted.Thanks a lots.

Empty may or may not also mean that a String only contains whitespace. If you're talking about Apache Commons Lang then they have a separate method for that, StringUtils.isBlank.

[Premila Devi Dayalan]

True,Agree with you :Empty may or may not also mean that a String only contains whitespace. If you're talking about Apache Commons Lang then they have a separate method for that, StringUtils.isBlank.

Noted with thanks.
