Amazon Software Development Engineer, II interview questions

// You are on a team that is creating a program to model stress on furniture. // Your task is to model the behavior of furniture under abuse such as // excessive weight or application of fire. There exists a prototype that // defines the following: class Furniture { /** * Furniture becomes unusable if enough weight is applied; the * algorithm depends on shape of furniture, the strength of material, and * the location where the weight is applied */ void applyWeight(double x, double y, double weight, double seconds); /** * Furniture becomes unusable if it is made of wood, and fire is applied * long enough; wood will change from brown to black if it is burnt * (whether or not the furniture becomes unusable) */ void applyFire(double x, double y, double fireStrength, double seconds); /** * possible values: Gray, Brown, Black, etc */ Color getColor(); /** * possible values: OK, UNUSABLE */ FurnitureState getState(); } class WoodChair extends Furniture {...} class SteelChair extends Furniture {...} class WoodTable extends Furniture {...} class SteelTable extends Furniture {...} class RubbrCouch // We will need to start adding other furniture like couches, beds, bookcases, and desks, and also new materials such as plastic, cloth, rubber, etc. Try to improve the class design - you are free to modify it however you wish since it is only a prototype.
