Description

Use UtilValidate's isEmpty and isNotEmpty methods correctly, like,
– used: if(!UtilValidate.isEmpty(productId)) correct use of it: if(UtilValidate.isNotEmpty(productId))
– used: if(!UtilValidate.isNotEmpty(productId)) correct use of it: if(UtilValidate.isEmpty(productId))
This would improve code readability of project.
