Translate this ADT into a Java interface:
ADT: Point
amplitude(): Real
distanceTo(Point): Real
equals(Point): Boolean
magnitude(): Real
toString(): String
xCoordinate(): Real
yCoordinate(): Real

Output:

None

Solution:

public interface Point {
 public double amplitude();
 public double distanceTo(Point point);
 public boolean equals(Object object);
 public double magnitude();
 public String toString();
 public double xCoordinate();
 public double yCoordinate();
}
