Peanut Butter and Jelly Sandwich
Due 03/29/2024 by 11:55pm
Objective:
Practice object-oriented principles by making two Peanut
Butter and Jelly Sandwiches. The program must create two sandwiches based on
user input. The sandwich information for both must then print out their details
and determine if the two sandwiches are equal.
Requirements:
- Functionality. (80pts)
- No Syntax Errors. (80pts*)
- *Code that cannot be compiled due to syntax errors is
nonfunctional code and will receive no points for this entire section.
- Write a class called Bread with the following:
(20pts)
- Instance Variables
- Name: The name brand of the bread. This value should
not be null, and its default value is “none”.
- Calories: The number of calories per slice assumed to
be between 50 and 250 inclusively, and its default value is 50.
- Type: The kind of bread. This can either be “Honey
Wheat”, “White”, “Whole Grain”, or “Whole Wheat”, and its default value
is “Whole Grain”.
- Methods
- Accessors and Mutators for the instance variables
- Make sure in the mutators check for valid values named
in the “Instance Variables” Section.
- If the value that is being set is not valid, then set
the instance variable to its default value.
- Equals: This method takes in another instance of Bread
and only returns true if all of the instance variables match. For name
and type case should be ignored.
- ToString: This method returns a string with all of the
instance variable values concatenated together.
- All above must apply for full credit.
- Write a class called PeanutButter with the
following: (20pts)
- Instance Variables
- Name: The name brand of peanut butter. This value
should not be null, and its default value is “none”.
- Calories: The number of calories per serving assumed to
be between 100 and 300 inclusively, and its default value is 100.
- IsCrunchy: True if the peanut butter is crunchy and
false otherwise, and its default value is false.
- Methods
- Accessors and Mutators for the instance variables
- Make sure in the mutators check for valid values named
in the “Instance Variables” Section.
- If the value that is being set is not valid, then set
the instance variable to its default value.
- Equals: This method takes in another instance of Peanut
Butter and only returns true if all of the instance variables match.
For name case should be ignored.
- ToString: This method returns a string with all of the
instance variable values concatenated together.
- All above must apply for full credit.
- Write a class called Jelly with the following:
(20pts)
- Instance Variables
- Name: The brand name of the Jelly. This value should
not be null, and its default value is “none”.
- Calories: The number of calories per serving assumed to
be between 50 and 200 inclusively, and its default value is 50.
- FruitType: The type of fruit the jelly is made from and
can only be “Apple”, “Blackberry”, “Grape”, “Blueberry”, or “Tomato”.
Its default value is “Grape”.
- Methods
- Accessors and Mutators for the instance variables
- Make sure in the mutators check for valid values named
in the “Instance Variables” Section.
- If the value that is being set is not valid, then set
the instance variable to its default value.
- Equals: This method takes in another instance of Jelly
and only returns true if all of the instance variables match. For name
and fruit type case should be ignored.
- ToString: This method returns a string with all of the
instance variable values concatenated together.
- All above must apply for full credit.
- Write a class called PBJSandwich with the
following: (10pts)
- Instance Variables
- TopSlice: An instance of type Bread representing the
top slice of bread. This type refers to the one that was described
above, and its default value is the default Bread.
- PeanutButter: An instance of type PeanutButter
representing the peanut butter. This type refers to the one that was
described above, and its default value is the default PeanutButter.
- Jelly: An instance of type Jelly representing the
jelly. This type refers to the one that was described above, and its
default value is the default Jelly.
- BottomSlice: Another instance of type Bread
representing the bottom slice of bread. This type refers to the one
that was described above, and its default value is the default Bread.
- Methods
- Accessors and Mutators for the instance variables
- Make sure in the mutators check for valid values named
in the Instance Variable Section.
- Each of the instance variables must not be null.
- Equals: This method takes in another instance of
PBJSandwich and only returns true if all of the instance variables
match by calling their Equals methods.
- ToString: This method returns a string with all of the
instance variable values.
- All above must apply for full credit.
- Write a class called PBJFrontEnd with the
following: (10pts)
- Methods
- Main Method
- The program must create two instances of type
PBJSandwich.
- User must be able to enter all the properties of the
sandwiches which include all the properties of the top slice of bread,
bottom slice of bread, jelly, and peanut butter.
- The program must then print out the values of the two
sandwiches which include all the properties of the top slice of bread,
bottom slice of bread, jelly, and peanut butter.
- The program must then determine if they are the same
sandwich.
- The program must then ask the user if they would like
to restart or quit.
- All above must apply for full credit.
- Coding Style. (10pts)
- Code functionality organized within multiple methods
other than the main method, and methods organized within multiple classes
where appropriate. (5pts)
- Readable Code. (5pts)
- Meaningful identifiers for data and methods.
- Proper indentation that clearly identifies statements
within the body of a class, a method, a branching statement, a loop
statement, etc.
- All the above must apply for full credit.
- Comments. (10pts)
- Your name in every file. (5pts)
- At least 5 meaningful comments in addition to your name.
These must describe the function of the code it is near. (5pts)
Example Dialog:
*The following Example Dialog demonstrates the interactions
between a user and ONE possible implementation of the required software’s
front-end / user interface. The software’s front-end / user interface may
be implemented in MANY different ways and will receive full credit as
long as it meets the most minimal of the above requirements. While you may use
the example dialog as a guide, it is strongly encouraged to create the
front-end / user interface in your own way. *
