variable, through the obj1 change I of the value, will affect the obj2;j is an instance variable, through obj1 change the value of J, does not affect the obj2. This is because obj1.i and obj2.i point to the same memory space, and OBJ1.J and OBJ2.J point to different memory spaces, see the following figure:Note: Static variables are initialized when the class is loaded. That is, as long as the class is loaded, it is initialized regardless of whether you use the static variable or not. Summary:

This always has something to represent the current object of the class, like the this pointer in C + +, the This keyword in Java is a reference that represents the current object. It has three main functions: 1, which calls other construction methods in the constructor method. For example, there is a student class with three constructors, and it is not possible to use this () directly using student () to invoke another constructor in one constru
