How to get instance number

Question

Is there way how to get instance number or id, I mean that what you can see in eclipse Debug>Variables window after class name in value column.

Thanks

Answer 1

See System.identityHashCode which returns the number that would be returned if Object.hashCode had not been overridden on an object. It is not a perfect proxy for identity since multiple objects might have the same identity hash code, but it is pretty useful for debugging.

Answer 2

By default, debugger shows you the result of toString() method with the hashCode of the object. So, you can see the value by executing hashCode() method.
