Intro to JAVA:

The Segment class describes a segment of the real line with a given start and end point. Have the class implement the Moveable interface. To move a segment, move its start and end points.

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; } }
