Getting a methods Return type via reflection

Question

I am getting the attributes from an incoming object which I will check it's values.

I wish to know if there is a way via reflection that I can obtain not only the value from attribute but also it's type?

would

result instanceof Integer.Class

work for example?

Answer 1

This should be the safest and most universal way. It's null-safe, you don't need an extra != null check:

SomeClass.class.isInstance(result)

Reference:

Class.isInstance(Object)

Answer 2

您可以使用result.getClass()

Answer 3

No.

Use Class.isAssignableFrom()
