What is the scope of variables in Java?

In Java, the scope of a variable refers to the region of the program where the variable is accessible. There are three main types: local, instance, and class variables.

Can you explain local variables in more detail?

Local variables are declared within a method or a block and can only be accessed within that method or block. They are created when the method is called and destroyed when it exits.

What about instance variables?

Instance variables are declared within a class but outside any method. They are tied to a specific instance of the class and can be accessed by all methods in that class.

And class variables?

Class variables, also known as static variables, are declared with the static keyword. They belong to the class itself rather than any instance and can be accessed without creating an object of the class.
