Invoking Private Methods through Reflection

Can you invoke a private method through reflection in Java?

Solution:

Yes, it is possible to invoke private methods using reflection. To do so, modify the code as follows:

Method method = object.getClass().getDeclaredMethod(methodName);
method.setAccessible(true);
Object r = method.invoke(object);

Additional Considerations:

• getDeclaredMethod only retrieves methods declared in the current class, not inherited methods.
• A security manager might restrict the use of setAccessible, requiring it to run as a privileged action.

By following these steps, you can access and invoke private methods via reflection.
