24.4. Limitations of Reflection

Try these first

1. 1.

   What is the main performance concern when using Reflection?

   Hint

   Think about how types are processed at runtime.

2. 2.

   What limitations does Reflection impose on accessing class members?

   Hint

   Consider how security policies affect access.

3. 3.

   What is a major drawback of using Reflection in Java?

   • A) Fast execution
   • B) Compile-time safety
   • C) Performance overhead

   Hint

   Think about how Reflection affects execution speed.

4. 4.

   True or False: Reflection can always access private members safely.

   • True
   • False

   Hint

   Recall the effect of security policies.

5. 5.

   Create a Java program that demonstrates the use of Reflection to access a private field along with a SecurityException handling mechanism.

   Hint

   Be aware of the Java access modifiers and how security managers work.

6. 6.

   Analyze a given code snippet using Reflection to show how it could lead to runtime errors and propose a strategy to reduce these risks.

   Hint

   Consider adding type checks before reflection operations.
