方法名：isAllLowerCase

StringUtils.isAllLowerCase介绍

[英]Checks if the CharSequence contains only lowercase characters.

null will return false. An empty CharSequence (length()=0) will return false.

StringUtils.isAllLowerCase(null)   = false 
StringUtils.isAllLowerCase("")     = false 
StringUtils.isAllLowerCase("  ")   = false 
StringUtils.isAllLowerCase("abc")  = true 
StringUtils.isAllLowerCase("abC")  = false 
StringUtils.isAllLowerCase("ab c") = false 
StringUtils.isAllLowerCase("ab1c") = false 
StringUtils.isAllLowerCase("ab/c") = false

[中]检查CharSequence是否仅包含小写字符。
null将返回false。空的CharSequence（length（）=0）将返回false。

StringUtils.isAllLowerCase(null)   = false 
StringUtils.isAllLowerCase("")     = false 
StringUtils.isAllLowerCase("  ")   = false 
StringUtils.isAllLowerCase("abc")  = true 
StringUtils.isAllLowerCase("abC")  = false 
StringUtils.isAllLowerCase("ab c") = false 
StringUtils.isAllLowerCase("ab1c") = false 
StringUtils.isAllLowerCase("ab/c") = false
