Through this week's learning, I learned the core of Java, understood the definition of user-defined class, understood the declaration of objects, understood the use of constructors to initialize objects, used class properties and methods, and understood the purpose of the package and import statements. You know, assuming you're dealing with an object in the real world, you're not going to separate its properties from the way it's handled, and so is programming. Object-oriented Programming (OOP): A new way of thinking is closer to the natural representation of human beings in dealing with real world problems. the object-oriented languages are: C++,smalltalk,java and so on. several key concepts of object-oriented programming: abstract data types, classes and objects, encapsulation, class hierarchies (subclasses), inheritance, polymorphism.
It's going to take painstaking effort.
