(B) True or False. 10
1 Class is group of objects with common properties and is like a blueprint from where
objects are created.
2 Two objects are said to be concurrent if two objects are same.
3 Dynamic model describes about the time of performing an event.
4 Encapsulation is a method of bundling data and methods which make use of data.
5 The advantages of using object modeling it cannot models the problem domain
objects
6 Meta data summarizes basic information about data.
7 Functional model describes the function of internal processes of a system
8 While designing an object classes and objects are encapsulated in a package.
9 In modeling design is a problem related to object domain in programming.
10 Object model is use to reduce development risk
