Concept:

Classes in java are the collection of objects which has some similar properties. A class in java contains fields, methods, constructors, blocks, interfaces.

Explanation:

Everything is associated with classes and objects. An object is an instance of the class which has some state and behavior.

An object class(java.lang.object) is the parent class of all the java classes.  It can be used when we do not know about the type of the object. By having the object as the super class , without knowing the type we can pass around objects using the object declaration.

• In the first stage, an initial estimate is arrived at; Over the next two stages, the initial estimate is refined to arrive at a more accurate estimate
• COCOMO uses both single and multivariable estimation models at different stages of estimation
• The three stages of COCOMO estimation technique are basic COCOMO, intermediate COCOMO, and complete COCOMO

Note:

COCOMO stands for Constructive Cost Estimation Model.

Here the pattern is,

0.15552 ÷ 0.3 = 0.5184,

0.5184 ÷ 0.3 = 1.728,

1.728 ÷ 0.3 = 5.76,

Similarly, we have :

5.76 ÷ 0.3 = 19.2
