1. The Java language Features- object-oriented programming . Everything is object, each object, we write a class that describes the behavior and properties of the object, the class is the description of the object, and the object is an instance of the class.
2. Instantiate an object, in Java, the new keyword is used to instantiate an object, the new operator creates an object in memory, and returns a reference to the newly created object.
3. The This keyword. Each object can use this to refer to itself, and if a method of a class needs to access a member variable or other method of the class itself, it should be referenced with this.
4. This chapter is a difficult, comparative abstraction, and hopefully will be able to make their relationship more thorough in the future.
