🚀 Accessing Static Members Using the Class Name in Java (Oop Concepts) In Java, static members are associated with the class itself, not with instances of the class. Consequently, you should always access static members using the class name, rather than an instance of the class or the `this` keyword. Using the class name clarifies that you are accessing a shared, class-level property or method. This promotes code clarity and avoids confusion about the scope of the variable or method. #oopconcepts #programming #coding #tech #learning #professional #career #development
