The Java Access Control Exception is a type of exception that occurs when an application attempts to access a resource or method that it doesn't have permission to access. This exception is part of Java’s security model, which is based on access control mechanisms to prevent unauthorized access. The exception typically arises when security managers enforce policies, such as those restricting file I/O, network access, or the manipulation of system properties.

This exception is used in security contexts, particularly when performing sensitive operations in a secured Java environment. Since the introduction of Java in 1995, access control exceptions have been essential for enforcing the security of Java applications, especially in environments such as web applications or enterprise systems. More details can be found in the official Java API documentation.
