Java Reflection Utility

Question

Is there a utility to get a property which isnt prefixed by get from an object using reflection similar to BeanUtils? e.g. if I specify "hashCode" and I want to get the object.hashCode() value.

Thanks.

Answer 1

You can call hashCode() on every Object. You don't need reflection for this.

Otherwise, you can use the standard reflection classes - java.lang.Class and its method getMethod(..) which returns java.lang.reflect.Method.

Answer 2

The java reflection API allows you to access any property on a given instance of a class, including private variables.

Reflection is a powerful tool that allows you to do many things, including instantiating objects with private constructors.

Here is a decent tutorial for reflection that a quick google search turned up.
