Static variable is shared across all the objects. You can only create one copy of a static variable. Furthermore, there is also a possibility to have static block, static method and static class.

To make a static member (block, variable, function, nested class), use the keyword static before declaring it. When a member is declared static, it can be accessible before any objects of its class are generated, and it can be accessed without requiring a reference to any object.
When a variable is marked as static, a single copy is made and shared across all objects in the class. Static variables, on the other hand, are effectively global variables. The static variable is shared by all instances of the class. Important considerations for static variables include:
Static methods are those that are declared using the static keyword. The main( ) method is a static method. Static methods are subject to the following constraints:
Static variables are initialized using a static block. Despite the fact that static variables can be initialized directly upon declaration, there are times when multiline processing is required.
Static blocks are in handy in these situations. A static block can be utilized if static variables require additional, multi-statement logic during setup.
We can create a class within a class in the Java programming language. It offers a persuasive approach of grouping items that will only be utilized in one place, making our code more ordered and readable.
