Question

JAVA PROGRAMMING:

Modify the following class to be a generic class. The generic types usable by FilteredData should implement the Comparable interface. Your tester (whether it be a tester class with a main method or a JUnit class) should test your new FilteredData class with at least two different generic types, say String and Integer, for example.

import java.util.ArrayList;

public class FilteredData {

   private ArrayList ds;
   private Measurable min;
   private Measurable max;

   public FilteredData() {
       ds = new ArrayList<>();
       min = null;
       max = null;
   }

   public void add(Measurable ele) {
       if ((min == null) || (min.getMeasure() > ele.getMeasure())) {
           min = ele;
       }

       if ((max == null) || (max.getMeasure() < ele.getMeasure())) {
           max = ele;
       }

       ds.add(ele);
   }

   public Measurable getMin() {
       return min;
   }

   public Measurable getMax() {
       return max;
   }

}

Explanation / Answer

public class BST { private class BSTNode implements Comparable { BSTNode left, right; E data; @Override public int compareTo(E o) { return 0;//implement method here } } private BSTNode root; public BST() { root = new BSTNode();//while comparing you would need to case E to comparable and call compareTo method } public static void main(String[] args) { BST messages = new BST(); } }
