I need to write a java program that to estimate the cost of painting a house, a painter needs to know the surface area of the exterior (assume the doors or windows have uniform size). I am a beginner at programming in java and have run into a lot of trouble trying to write the program).The input are the width,length, and height of the house, the number of windows and doors and their dimensions.

Sorry, this is in 2D, but it's already drawn so I'm not turning back now:

//GET HOUSE SIZE //GET # OF WINDOWS AND DOORS //SUBSTITUTE INTO EQUATION surfaceArea = (houseWidth * houseHeight * 4); surfaceArea -= (numberOfDoors * (doorWidth * doorHeight)); surfaceArea -= (numberOfWindows * (windowWidth * windowHeight));

For a cube house with

**4 walls**.
