LAB3 PART1
READ THE REQUIREMENT, CREATE UML FOR DATATYPE CLASS AND THE PSEUDO-CODE FOR main() BEFORE WRITING THE CODE
REQUIREMENT
You must use Object Oriented Programming to provide this project.
The project has two classes:
- datatype class: SU2022_Adult_yourLastName (DOWNLOAD CLASS Adult.java FROM ECAMPUS THEN PASTE ITS CONTENT TO YOUR DATATYPE CLASS SU2022_Adult_yourLastNaame)
- driver class:
DATA TYPE CLASS
From now and on, before writing the code of a data type class, you must create the UML of the data type
If you do not have any tool to create UML, you can create in Word one table with 1 column x 3 rows as below.
|
SU2022_Adult_White |
|
-name: String -height: int -expectedBMI: float |
|
+SU2022_Adult_White() +SU2022_Adult_White(name:String, height:int, respectedBMI:float) +setName(name:String) +setHeight(height:int) +setBMIExpected(BMI:float) +getName():String +getHeight():int +getBMIExpected():float +calculateWeight(): float +toString(): String |
|
|
-the first row for class name in the middle
-the second row for the list of data members (variables) with the minus sign (-) at the beginning of each one. Minus(-) means private access.
-variableName:dataType
-the third row lists all constructors and methods with the plus sign (+) at the beginning of each one. Plus sign (+) means public access
Constructors:
+className()
+className(parameterName:type, …)
Methods:
+methodName():returnType
+methodName(parameterName:type, …): returnType
WRITE THE CODE OF DATATYPE CLASS:
To write the code for Datatype class, you should base on the UML above
This is the first time you learn how to write the code of a datatype class. Therefore, to help you to understand how the datatype class looks like, download the class Adult from eCampus, then copy and paste the code of the class Adult to your datatype class SU2022_Adult_yourLastName.
Compare the code with the UML to learn how to write the code of datatype class to apply for other datatype class in other labs.
For any questions, contact your instructor at LiemLe@dcccd.edu to get help.
DRIVER CLASS
Before writing the code, you must create the pseudo-code for the main().
The driver class named SU2022_YourtWeightManagement_yourLastName includes the function public static main(String[] args)
In the function main(), after reading all the information of one adult including name (String), height(int) and expected BMI rate (float), you must create the object of the datatype class above SU2022_Adult_yourLastname by calling parameterized constructor of the datatype class, then use this object to access the method toString() to display the result of the weight.
The syntax to create the object of one datatype class as below:
ClassName objectName = new ClassName(information1, information2, etc. );
The syntax to use the object to access methods of datatype class as below:
objectName.methodName();
To learn more how to create an object with parameterized constructor and how to use object to access methods of datatype class, read topics in HOW TO DO LAB
After using the object to access the method toString() the output should be, for example:
---------------------------------------------
File: SU2022_YourWeightManagement_White.java
Your Weight Management – McKINLEY WHITE
Standard BMI: 18.5 – 24.9
---------------------------------------------
Name: Mary Lane
Height: 82
BMI Expected: 19.65
---------------------------------------------
Weight: 187.95
