- 17. Implementation (software) The System dynamically loads and activates a corresponding Java Class for each tile ID. Each Java program also dynamically checks nearby tile classes and interfaces. public class WebCamTile extends Tile implements ImageCreateInterface , TimeMachineInterface , … { …… …… } …… Tile t = getLeftTile(); if (t instanceof TimeMachineInterface ) { … .. } … .
