java.lang.Character isISOControl(char ch)
Description
This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the isISOControl(int) method.
The isISOControl(char ch) 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.isISOControl(char ch)
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 isISOControl() method non statically.
