In Java, static variables are also called class variables.
That is, they belong to a class and not a particular instance.
As a result, class initialization will initialize static variables.16 jan. 2024
Static variables can be accessed by calling with the class name ClassName.
VariableName.
When declaring class variables as public static final, then variable names (constants) are all in upper case.
If the static variables are not public and final, the naming syntax is the same as instance and local variables.
In the Java programming language, the keyword static means that the particular member belongs to a type itself, rather than to an instance of that type.
This means we'll create only one instance of that static member that's shared across all instances of the class.8 jan. 2024
A class can be declared static only if it is a nested class.
It does not require any reference of the outer class.
The property of the static class is that it does not allows us to access the non-static members of the outer class.
