Question :

You have developed a Web-based application for a bank. The application stores all the information about its employees and customers. The database used in the bank application also stores photographs of its employees and customers along with their personal details. In the testing phase, you have realized that the application is taking a long time to display the output. As a result, you decided to change the design of the application to improve its performance.

Question :

Consider that you have an abstract base class, Shape, with an abstract method, makeShape(), to draw a shape on the screen. Two classes, Circle and Square, are derived from the Shape class and provide definitions of the makeShape() method. Depending upon the specification by an end user, either a circle or an square is drawn. To draw the any shape, you need to create and use object of either Circle class or Square class and use the makeShape() method of the Shape abstract class.

To solve this problem you apply a design pattern, according to which, you need another class that provides a method to create the objects of the Circle and Square classes. Which design pattern is applied here?

1,Facade

2,Decorator

3,Factory

4,Proxy

Question :

You are assigned to create an application for the bank that calculated interest amount on each type of the bank account. Consider that you have an abstract base class, Account, with an abstract method, CalculateInterest(), to calculate interest on saving account, current account, loan account. Three classes, SavingsAccount and CurrentAccount, and LoanAccount are derived from the Account class and provide definitions of the CalulateInterest() method. Depending upon the specification by a bank clerk, either the interest amount on a saving account or current account or loan account is calculated. To calculate interest, you need to create and use object of either SavingsAccount or CurrentAccount, or LoanAccount class and use the CalculateInterest() method of the Account abstract class.

Which design pattern will you implement on the Account Manager class?

Question :

You are assigned the task of developing an RAS application. Currently you are working in the designing phase of the application. When you create a blueprint for the application, you observe the following conditions applicable to the design:

-- A class can record the instances of another class.

-- A class can use the objects of another class.

-- A class can provide information to initialise the objects of another class.

Keeping all these conditions in mind, which design pattern should you implement in the application so that it become more reusable and manageable?
