What does the scope of an identifier indicate?

The scope of an identifier refers specifically to where that identifier is accessible within the code. In programming, the scope determines the visibility and lifetime of a variable or method, indicating which parts of the program can use or reference that identifier. For example, a variable defined within a method has a local scope, meaning it cannot be accessed outside of that method. Conversely, a variable defined at the class level has a broader scope and can be accessed by other methods within the same class.

This concept is crucial in Java and other programming languages, as it helps manage variable names and memory efficiently, preventing conflicts and ensuring that different parts of the program can operate without interfering with each other. Understanding the scope of identifiers aids in writing clear and bug-free code.
