The Segment class describes a segment of the real line with a given start and end point. Have the class implement the Measurable interface. The measure of a segment is the length. For example, the segment from 1 to 5 has length 4, as does the segment from 5 to 1.

CODE:

public class Segment { private double start; private double end;

/** Constructs a linear segment. @param from the starting point @param to the ending point */ public Segment(double from, double to) { start = from; end = to; }

public String toString() { return start + "->" + end; } }

Measurable.java 1 2 Describes any class whose objects can be measured 4 public interface Measurable k x Computes the measure of the object. @return the measure 10 double getMeasure()
