Use Netbeans to copy your last lab (Lab 07) to a new project called La.pdf
- 1. Use Netbeans to copy your last lab (Lab 07) to a new project called Lab08. Close Lab07. Work on the new Lab08 project then. The Student class A Student is a Person with 3 extra attributes, major, academic year and gpa. Attributes String major String academicYear double GPA Constructorsone constructor with no input parameterssince it doesn't have input parameters, use the default data below major - IST academicYear - Sr. GPA - 3.0 remember to call the constructor of the superclass with no parameters one constructor with all the parameters all three parameters from Student, one for each attribute since this is a subclass, remember to include also the parameters for the superclass Methods Get and Set methods (a requirement from encapsulation) public String toString() returns this object as a String, i.e., make each attribute a String, concatenate all strings and return as one String. toString() is a special method, you will learn more about it in the next lessons
- 2. it needs to be public it needs to have @override notation (on the line above the method itself). Netbeans will suggest you do it. important : in the subclass toString, remember to make a call to the superclass toString so that the resulting String includes data from the subclass Student data from the superclass Person The Person Class Attributes String firstName String lastName String hometown String state Height height Constructorsone constructor with no input parameterssince it doesn't receive any input values, you need to use the default values below: firstName - No lastName - Name hometown - N/A state - N/A height - use the Height class no parameter constructor one constructor with three parameters firstName using the input parameter lastName using the input parameter height using the input parameter
- 3. use the default values for hometown - N/A state - N/A one constructor with all (five) parameters one input parameter for each attribute Methods Get and Set methods (a requirement from encapsulation) important: You should start generating the default get and set methods using NetBeans automatic generator Then you will change getFirstName and setLastName as specified. getFirstName returns firstName with the first letter in upper case and the remaining of the String in lower case getLastName getHometown getState getHeight setFirstName setLastName updates lastName to be all caps (all upper case) remember to use setLastName in all constructors so the data (the updated lastName) is stored correctly setHometown setState setHeight public String toString()
- 4. returns this object as a String, i.e., make each attribute a String, concatenate all strings and return as one String. toString() is a special method, you will learn more about it in the next lessons it needs to be public it needs to have @override notation (on the line above the method itself). Netbeans will suggest you do it. regarding state , the toString method will have a similar functionality as App had in the first lab. if the state attribute is "PA", display the object's attribute name plus the message "is from Pennsylvania" if the state attribute is not "PA", display the object's attribute name plus the message "is from out-of-state" In short, the toString() method returns all the data from each object as a String public void initials ( )this method gets firstName and lastName extract the initials of each one of them adds a "." period to each of them and uses "System.out.println" to display them as one String public void initials ( int option) this method overloads public void initials( ) . This means, it has the same name, but a different number of parameters. if the value of "option" is 1 gets firstName extract its initials adds a "." period to to a String adds the lastName to this String and uses "System.out.println" to display the String if the value of "option" is 2
- 5. adds firsName to a String gets lastName extract its initials adds a "." period to it adds it to the String and uses "System.out.println" to display the String The Height class uses encapsulation private attributes get and set methods for each attribute Attributes int feet int inches Constructorsone constructor with no input parameterssince it doesn't receive any input values, you need to use the default values below: feet - 5 feet - 6 one constructor with two parameters feet using the input parameter inches using the input parameter Methodspublic String toString() returns this object as a String, i.e., make each attribute a String, concatenate all strings and return as one String. toString() is a special method, you will learn more about it in the next lessons
- 6. it needs to be public it needs to have @override notation (on the line above the method itself). Netbeans will suggest you do it. The Player Class ( now an abstract class ) Player is a Student with some extra attributes Uses encapsulation Player now is an abstract class because it has an abstract methodpublic abstract double getRatings( ); an abstract method is an incomplete method that has to be implemented by the subclasses. Attributes private int number private String sports private gamesPlayed Constructorsone constructor with no input parameterssince it doesn't receive any input values, you need to use the default values below: number - 0 sports - "none" gamesPlayed - 0 one constructor with all parameters one input parameter for each attribute Methods public String toString() returns this object as a String, i.e., make each attribute a String, concatenate all strings and return as one String. toString() is a special method, you will learn more about it in the next lessons
- 7. it needs to be public it needs to have @override notation (on the line above the method itself). Netbeans will suggest you do it. Get and Set methods public int getNumber() public void setNumber(int number) public String getSports() public void setSports(String sports) public int getGamesPlayed() public void setGamesPlayed(int gamesPlayed) public abstract getRatings(); The SoccerPlayer Class SoccerPlayer is a Player with some extra attributes Uses encapsulation SoccerPlayer will implement the method getRatings (an abstract method from the superclass Player) toString has to include the result of getRatings() too Attributes private int goals private int yellowCards Constructorsone constructor with no input parameterssince it doesn't receive any input values, you need to use the default values below: goals - 0 yellowCards - 0 one constructor with all (two) parameters
- 8. one input parameter for each attribute Methods public String toString() returns this object as a String, i.e., make each attribute a String, concatenate all strings and return as one String. toString() is a special method, you will learn more about it in the next lessons it needs to be public it needs to have @override notation (on the line above the method itself). Netbeans will suggest you do it. should also include the value of getRatings() in the string Get and Set methods public int getGoals() public void setGoals(int goals) public int getYellowCards() public void setYellowCards(int yellowCards) public double getRatings()calculate and return the ratings using this formula:(double) (goals - yellowCards)/gamesPlayed the (double) is called casting, forcing the expression that comes afterwards to become a double. it is necessary to avoid getting 0 as a result because of the precision loss in the division by integers if goals or gamesPlayed is 0, return 0 (you need to do this test to avoid the application crashing in case one of them is 0) The FootballPlayer Class FootballPlayer is a Player with some extra attributes Uses encapsulation
- 9. FootballPlayer will implement the method getRatings (an abstract method from the superclass Player) toString has to include the result of getRatings() too Attributes private int yards private int minutesPlayed Constructorsone constructor with no input parameterssince it doesn't receive any input values, you need to use the default values below: yards - 0 minutesPlayed - 0 one constructor with all (two) parameters one input parameter for each attribute Methods public String toString() returns this object as a String, i.e., make each attribute a String, concatenate all strings and return as one String. toString() is a special method, you will learn more about it in the next lessons it needs to be public it needs to have @override notation (on the line above the method itself). Netbeans will suggest you do it. should also include the value of getRatings() in the string Get and Set methods public int getYards() public void getYards(int yards) public int getMinutesPlayed()
- 10. public void setMinutesPlayed(int minutesPlayed) public double getRatings()calculate and return the ratings using this formula:(double) ( (yards - minutesPlayed/10.0) ) /gamesPlayed be careful with the parenthesis to avoid getting 0 as a result the (double) is called casting, forcing the expression that comes afterward to become a double. it is necessary to avoid getting 0 as a result because of the precision loss in the division by integers use 10.0 instead of 10 to force Java to use more precision in the calculation if yards or gamesPlayed is 0, return 0 (you need to do this test to avoid the application crashing in case one of them is 0) The App class create a SoccerPlayer object called sp0 using the no-parameter constructor create a SoccerPlayer object called sp1 using the all-parameter constructor with the values goals - 5 yellowCards - 2 number - 7 sports - Soccer gamesPlayed - 10 major - Cyber academicYear - Sr. GPA - 3.5 firstName - jillian (see the different capitalization used to test the get/set methods) lastName - Jennings height 5 7 hometown - Montclair
- 11. state - NJ create a FootballPlayer object called fp0 using the no-parameter create a FootballPlayer object called fp1 using the all-parameter constructor with the values yards - 60 minutesPlayed -30 number - 26 sports - Football gamesPlayed - 10 major - IST academicYear - Jr. GPA - 3.5 firstName - KEATON (see the different capitalization used to test the get/set methods) lastName - Ellis height 5 11 hometown - State College state - PA display all the data from each object Output Important you need to display each class toString( ) in a separate line. You can do this by adding a "n" at the end of the string. In the last toString you will also add a "==============================================================" String to close the line.
- 12. PLEASE PROVIDE ALL CODE FOR APP, PERSON, HEIGHT, STUDENT, PLAYER(ABSTRACT), FOOTBALLPLAYER, AND SOCCER PLAYER. THE OUTPUT SHALL BE THE SAME AS PICTURED. Person { firstName=No, lastName=NAME, hometown=N/A, state=N/A, height=Height { feet = 5 , inches = 6 }} Student { major = I ST , academicYear = S r , GP A = 3.0 } Player { number = 0 , sports=none, gamesplayed = 0 } SoccerPlayer { goals = 0 , yellowCards = 0 , ratings = 0.0 } Person { firstName=Jillian, lastName=JENNINGS, hometown=Montclair, state=out-of-state, height=Height { feet=5, inches=7 }} Student { major = Cyber, academicYear = Sr , GPA = 3.5 } Player { number = 7 , sports=Soccer, gamesPlayed = 10 } Soccerplayer { goals = 5 , yellowCards = 2 , ratings = 0.3 } Person { firstName=No, lastName=NAME, hometown=N/A, state=N/A, height = Height { f feet = 5 , inches = 6 }} Student { major = I ST , academicYear = Sr , GPA = 3.0 } Player { number = 0 , sports=none, gamesPlayed = 0 } FootballPlayer { yards = 0 , minutes 1 layed = 0 , ratings = 0.0 } Person { firstName=Keaton, lastName=ELLIS, hometown=State College, state=Pennsylvania, height=Height { feet = 5 , inches=11 }} Student { major = I ST , academicYear = J r . , GPA = 3.5 } Player { number = 26 , sports = Football, gamesPlayed = 10 } Footballplayer { y ards = 60 , minutesplayed = 30 , ratings = 5.7 }
