Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Reflection is a powerful Java feature that allows a program at runtime to modify or examine its own metadata, behavior and structure. It allows you to dynamically inspect classes, methods, interfaces and fields as well as their modifiers and annotations. Reflection allows you to inspect and manipulate Java objects even if their types are unknown during compile time. Java Course in Pune
Reflection allows you to access private methods and fields, call methods dynamically, create instances of classes and modify array types. This feature is especially useful for frameworks, libraries and applications that require generic algorithms to be able to work with any object type or when configuration and extensibility play a key role. Reflection should only be used sparingly, as its dynamic nature can result in less maintainable code and lower performance due to the potential to break encapsulation.
Reflection in Java provides flexibility and dynamic to Java applications. It allows developers to write generic, adaptable and reusable codes. However, it should only be used sparingly, with consideration for its impact on performance and design. Java Classes in Pune
