4 cards from this section. Quick, good the night before a test.
What method would you use to access private fields of a class?
Think about which method gives you access regardless of visibility.
Which method provides only accessible methods of a class?
Consider what 'accessible' means in this context.
What does getDeclaredFields() return?
Consider what 'declared' implies.
True or False: getMethods() retrieves private methods.
Think about method accessibility.
Write a program using reflection that inspects a custom class with multiple private fields and methods, modifies a field, and invokes a method dynamically. Document your code with comments explaining each step.
Start with defining the class first, then apply reflection methods.
Construct a scenario where using reflection might cause performance issues in a large-scale application. Discuss how you would mitigate this issue.
Consider how often you need to access and modify fields/methods dynamically.
