Static variables used in Java

As we all know, we can create multiple objects of this class based on a class, each with its own members and independent of each other. At some point, however, we would prefer all objects of the class to share the same member. This is the time for static!!

Members in Java that are decorated statically are called static members or class members. It is owned by the entire class, not by an object, which is shared by all objects of the class. Static members can be accessed directly by using the class name or by using the object name. Of course, given the particularity of his role, it is more recommended to access the class name ~ ~

Use static to modify variables, methods, and blocks of code.

In this section, let's take a look at static variables first.

For example, we define a static variable hobby in the class, and the operation code is as follows:

Operation Result:

Note: static members belong to the entire class, and when the system first uses the class, it allocates memory space until the class is unloaded for resource recycling! ~~
