need basic information

1.See there are three different types of objects.
tangible
intangible and conceptual i want one example of each of them.

2. why should we use OOA as opposed to Procedural/structural approach.

[Gavin Tranter]

These sound a little like home work to me.

1) Try a google search I am sure this will be able to define each of the 3 concepts and give examples.
2) Google OOA, I am sure there are a lot of articales that will allow you to draw a conclusion as to why we would want to use OOA principles, and hopefully cases where you may not wwant too.

I have never heard of the distinction between "tangible", "intangible" and "conceptual" objects, these are not concepts that have a specific meaning with regard to Java. Where did you learn about these?
