What is the relationship between local and global identifiers?

Local identifiers, also known as local variables, are defined within a specific method or block of code and can only be accessed within that particular scope. On the other hand, global identifiers, typically referred to as class variables or instance variables, are declared at the class level and can be accessed by all methods within the class.

The correct answer highlights that local identifiers have the ability to access global identifiers because they fall within the broader scope of the class. This access allows local variables to utilize and manipulate data stored in global variables. However, the reverse is not true—global identifiers do not have access to local identifiers because local variables exist only within the confines of their specific method or block. They are not recognized outside of their immediate context, thus protecting the integrity and scope of the data they represent.

Understanding this relationship is essential for correctly managing variable scope and avoiding potential errors in code. It emphasizes the importance of knowing how different levels of variable declaration impact the visibility and accessibility of those variables throughout a Java program.
