StringUtils.isNotBlank is convenient for empty judgment and null judgment in java

I feel that the writing style is different depending on the person, so I thought I wanted to unify it. Returns false when the String is empty, just spaces, or null.

StringUtils.isNotBlank(String str)

 StringUtils.isNotBlank(null)      = false
 StringUtils.isNotBlank("")        = false
 StringUtils.isNotBlank(" ")       = false
 StringUtils.isNotBlank("bob")     = true
 StringUtils.isNotBlank("  bob  ") = true

There are many other useful things. https://www.sejuku.net/blog/19323 ↑ Although it is summarized by Samurai Blog, I definitely want to actively look at the official as an engineer's edge. ↓ Official https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html
