Getting a methods Return type via reflection

I am getting the attributes from an 开发者_JAVA百科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?

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)

---

You can use result.getClass()

No.

Use Class.isAssignableFrom()
