I am unable to find a scenario where java.lang.Void wrapper class can be used.
Can you please help me in finding where java.lang.Void wrapper class can be used in my code?

One use - possibly the only one - is as the object returned by java.lang.reflect.Method.getReturnType(), for a method with void return type.
Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.

You can search for "java.lang.Void" in this forum as it has been discussed earlier. Basically you may understand it while getting the return type of a void method using reflection api.

Is it not also used in JNI to represent void return types from the native layer (assuming the native layer is C/C++).
Been awhile since I have used JNI.
I agree. Here's the link:
