java.lang.Boolean valueOf(String s)
Description
Make a note that the valueOf(String s) method of Boolean class is static thus it should be accessed statically. What I mean to say is that we should use this method such as below:
Boolean.valueOf(method args)
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 valueOf(String s) method non statically.
