Solutions

Expert Solution

1.

Utility class category has static methods and constants, but no objects.

Utility class can't allow to do the instantiation.

Utility class found to be as stateless.

Utility class has static methods which are reused.

Option C

2.

InitialLevel an appropriate name for a game-related class.

Starting of the game execute a class which is an appropriate name for a game-related class.

Don't think about first, second, .. levels to include the name.

Option B

3.

A class (ClassOne) is considered to have a dependency on class (ClassTwo) under condition

ClassOne uses objects of ClassTwo

In this dependent class is ClassOne

ClassTwo contains the required data which is needed by the ClassOne.

The usage of one class by the other class done using the objects.

Option D

4.

A UML class diagram would be most useful in visually illustrating dependencies between classes.

Dependency relation is referred as relationship an element or the group of elements required by the other model.

In UML class diagram one class elements used by the other class for their, so one class is dependent and other class is supplier.

Option C

You shall implement six static methods in a class named BasicBioinformatics. Each of the methods will perform some analysis of data considered to be DNA. DNA shall be represented arrays of chars containing only the characters A, C, G and T. In addition to the six methods you will implement, six other methods exist in the class, which use Strings instead of char arrays to represent DNA. These other methods simply invoke the methods you are to implement, so all...

Write a Java application, and an additional class to represent some real-world entity such as a technology item, an animal, a person, a vehicle, etc. Keep in mind that a class is a model in code of something real or imagined, which has attributes (member variables) and behaviors (member methods). The class will: Create a total of 5 member variables for the class, selecting the appropriate data types for each field. For example, a class to represent a lamp might...
