Question
Here is the Data class code:
package Unit5;
public class Data
{
/**
Computes the average of the measures of the given objects.
@param objects an array of Measurable objects
@return the average of the measures
*/
public static double average(Measurable[] objects)
{
double sum = 0;
for (Measurable obj : objects)
{
sum = sum + obj.getMeasure();
}
if (objects.length > 0) { return sum / objects.length; }
else { return 0; }
}
}
The assignment is to:
Add a method
public static Measurable max(Measurable[] objects)
to the Data class (given in the example files) that returns the object with the largest measure.
A person has a name and height in centimeters. Use the Data class of Exercise 1 to process an array of Person objects. Display the average height and the name of the tallest person.
Add a method to the Data class the returns an object with the largest measure, as measured by the supplied measurer:
public static Object max(Objects[] objects, Measurer m)
