Modularity: It lets the developer better separate tasks that should not be inextricably tangled, such as mathematical operations and exception handling.
Performance: It improves performance because the operations are more succinct. Development Time and Maintenance Time: It allows programmers to spend less time rewriting the same code. Overall, AOP enables better encapsulation of distinct procedures and promotes future interoperation, hence maintenance is comparatively easy.
Functionality: Using aspects it is possible to add new functionality without modifying the base program.
Testing: AOP can be used with software testing. Advices can be bound to method calls to measure invocation counts and execution time
