The abstract shape class Example 23.13: The abstract shape class package elharo.vrml; public abstract class shape { double x = 0.0; double y = 0.0; double z = 0.0; public void moveTo(double x, double y, double z) { this.x = x; this.y = y; this.z = z; } public void moveRelative(double x, double y, double z) { this.x += x; this.y += y; this.z += z; } public abstract String draw() ; } This class is subclassed to provide implementations for specific shapes like cubes, spheres and cones.
