java.lang.Character isUpperCase(int codePoint)
Description
A character is uppercase if its general category type, provided by getType(codePoint), is UPPERCASE_LETTER, or it has contributory property Other_Uppercase as defined by the Unicode Standard.
The isUpperCase(int codePoint) method of Character class is static thus it should be accessed statically which means the we would be calling this method in this format:
Character.isUpperCase(int codePoint)
Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java isUpperCase() method non statically.
