You may not add any instance variables to any class, though you may create local variables inside of a method to accomplish its task. No other methods should be created other than the ones listed here. (I need step 2 please.)
Step 1
Develop the following class:
Class
Name: CollegeDegree
Access Modifier: public
Instance variables
Name: major
Access modifier: private
Data type: String
Name: numberOfCourses
Access modifier: private
Data type: int
Name: courseNameArray
Access modifier: private
Data type: String [ ]
Name: courseCreditArray
Access modifier: private
Data type: int [ ]
Static variables
Name: maximumNumberOfCourses
Access modifier: private
Data type: int
Initial Value: 40
Constructor
Name: CollegeDegree
Access modifier: public
Parameters: none (default constructor)
Task: sets major to the empty string
Sets numberOfCourses to 0
Sets courseNameArray to refer to an array of Strings with the number of elements equal to the value of the static variable maximumNumberOfCourses
Sets courseCreditArray to refer to an array of ints with the number of elements equal to the value of the static variable maximumNumberOfCourses
Non-static Methods
Name: setMajor
Access modifier: public
Parameters: newMajor
Return type: void
Task: sets the value of the instance variable major to the value of newMajor
Name: getMajor
Access modifier: public
Parameters: none
Return type: String
Task: returns the value of the instance variable major
Name: addCourse
Access modifier: public
Parameters: courseName (data type String), numberOfCredits (data type int)
Return type: void
Task: if numberOfCredits is greater than or equal to 1 and less than or equal to 5 and numberOfCourses is less than the length of the courseNameArray then place the value of courseName into the courseNameArray in the element whose index is equal to the instance variable numberOfCourses and place the value of numberOfCredits into the courseCreditArray in the element whose index is equal to the instance variable numberOfCourses and then increase the value of the instance variable numberOfCourses by 1
Name: getCourses
Access modifier: public
Parameters: none
Return type: String
Task: returns the concatenation of the name of each course located in the courseNameArray (Note: This can be accomplished by looping through the part of the courseNameArray that is filled with course names and concatenating each of these values into a single string)
Name: getNumberOfCourses
Access modifier: public
Parameters: none
Return type: int
Task: returns the value of the instance variable numberOfCourses
Name: getTotalNumberOfCredits
Access modifier: public
Parameters: none
Return type: int
Task: returns sum of the all the credits in the courseCreditArray (Note: This can be accomplished by looping through the part of the courseCreditArray that is filled with course credits and summing these into a single int)
Static Methods
Name: increaseMaximumNumberOfCourses
Access modifier: public
Parameters: nexMaximumNumberOfCourses
Return type: void
Task: if the value of nexMaximumNumberOfCourses is greater than the value of the static variable maximumNumberOfCourses then change the value of maximumNumberOfCourses to the value of newMaximumNumberOfCourses
Name: getMaximumNumberOfCourses
Access modifier: public
Parameters: none
Return type: int
Task: returns the value of the static variable maximumNumberOfCourses
Step 2
Develop a class with only a main method in it:
import java.util.Scanner;
public class CollegeDegreeDemo {
public static void main(String[] args) {
/* Inside of this main method do the following:
Create an object of the Scanner class that takes input from System.in and refer to this object as keyboard
Create an object of the CollegeDegree class and refer to this object as myDegree
Create a variable of the int data type called option
Open a do/while loop
Prompt the user to pick one of the following options:
Press 1 to change the major of the degree
Press 2 to view the major of the degree
Press 3 to add a course to the degree
Press 4 to view all the courses required for the degree
Press 5 to view the number of courses required for the degree
Press 6 to view the total number of credits required for the degree
Press 7 to increase the maximum number of courses for all degrees
Press 8 to view the maximum number of courses for all degrees
Press 9 to the end the program
Save the user’s input into the option variable
if the user picks option 1, prompt the user for the major of the degree and save their input into a variable called newMajor and change the major of myDegree to the newMajor
else if the user picks option 2, display the major of myDegree
else if the user picks option 3, prompt the user for the name of the course and save this input into variable called courseName and prompt the user for the number of credits and save this input into a variable called numberOfCredits and add this course to myDegree
else if the user picks option 4, display the names of all the courses that are required for myDegree
else if the user picks option 5, display the number of courses that are required for myDegree
else if the user picks option 6, display the total number of credits that are required for myDegree
else if the user picks option 7, prompt the user for the new maximum number of courses and save this input into a variable called newMaximumNumberOfCourses and increase the number of maximum courses for all college degrees
else if the user picks option 8, display maximum number of courses for all degrees
else if the user picks option 9, display Goodbye.
else if the user picks any other option, display Error!
close the do/while loop and make it so that it continues to run as long as the user does not pick option 9
*/
}
