Question
Chapter 9, Problem 18PE
Program Plan Intro
Display average height and name of the tallest person
Program plan:
- In a file “Measurable.java”,
- Create the interface “Measurable”,
- Declare a method “getMeasure()”.
- Create the interface “Measurable”,
- In a file “Data.java”, create a class “Data”,
- Define a method “average()”,
- Initialize the “sum” variable.
- Create “for” loop to iterate objects,
- Update sum value.
- Check whether the value is positive,
-
- Return the value.
- Otherwise,
-
- Return “0”.
- Update sum value.
- Define a method “max()”,
- Check whether the measure of object is “0”,
- If it is true, return null value.
- Assign the object.
- Make “for” loop to traverse objects,
-
- Check whether the current object measure is greater than the maximum object measure.
- If it is true, assign the maximum measures of object.
- Check whether the current object measure is greater than the maximum object measure.
- Return the value that has maximum measures.
- If it is true, return null value.
- Check whether the measure of object is “0”,
- Define a method “average()”,
- In a file “Person.java”, create a class “Person” that implements “Measurable” interface,
- Declare the necessary variables.
- Define the parameterized constructor,
- Assign the initial values.
- Define a method “getHeight()” to return the height.
- Define a method “getName()” to return the name of the person.
- Define a method “getMeasure()” to return the height for Measurable interface.
- In a file “PersonTest.java”, create a class “PersonTest”,
- Define the method “main()”,
- Create an array of objects.
- Call the constructor to assign the values.
- Assign the value returned from the method “average()”.
- Assign the value returned from the method “max()”.
- Print the average and expected height.
- Print the name of the tallest person.
- Define the method “main()”,
