The code that may throw an exception is placed inside a try block, and any code to handle the exception is placed inside a catch block. Java reflection is a powerful feature that allows Java programs to inspect and modify the behavior of objects at runtime. In Java, exceptions are handled using a try-catch block. Consequently, programmers should avoid using the reflection. Nevertheless, to become an advanced Java developer, gaining a solid understanding of reflection (also. However, it is frequently misunderstood or misused, and certain aspects of its API and design are rather clunky and, in places, out of date. Explain Java reflection and give an example Use of reflection complicates security analysis and can easily introduce security vulnerabilities. Reflection is one of the most flexible and powerful techniques Java developers have at their command.
