In Java, the scope of a variable refers to the portion of the program where the variable can be accessed or used. There are different types of variable scope in Java, including:
Local scope: A variable declared within a method or block has local scope, meaning it can only be accessed within that method or block.
Instance scope: A variable declared within a class but outside of any method or block has instance scope, meaning it can be accessed by any method of the class.
Class scope: A variable declared as static within a class has class scope, meaning it can be accessed by any method of the class or any object of the class, regardless of the object's state.
Block scope:A variable declared within a block (such as a for loop or an if statement) has block scope, meaning it can be accessed within the block in which it is declared and also any nested block inside that block.
