类名称：StringUtils
方法名：isAllUpperCase

StringUtils.isAllUpperCase介绍

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

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

StringUtils.isAllUpperCase(null)   = false 
StringUtils.isAllUpperCase("")     = false 
StringUtils.isAllUpperCase("  ")   = false 
StringUtils.isAllUpperCase("ABC")  = true 
StringUtils.isAllUpperCase("aBC")  = false 
StringUtils.isAllUpperCase("A C")  = false 
StringUtils.isAllUpperCase("A1C")  = false 
StringUtils.isAllUpperCase("A/C")  = false

[中]检查字符序列是否仅包含大写字符。
null将返回false。空字符串（length（）=0）将返回false。

StringUtils.isAllUpperCase(null)   = false 
StringUtils.isAllUpperCase("")     = false 
StringUtils.isAllUpperCase("  ")   = false 
StringUtils.isAllUpperCase("ABC")  = true 
StringUtils.isAllUpperCase("aBC")  = false 
StringUtils.isAllUpperCase("A C")  = false 
StringUtils.isAllUpperCase("A1C")  = false 
StringUtils.isAllUpperCase("A/C")  = false
