Join Peggy Fisher for an in-depth discussion in this video Solution: Simple calculation, part of Learning Java.
(gentle music)…- I hope you had fun with that challenge…but I also wanna say don't be discouraged…if this is your first time…and you found it a little difficult.…What I'd like to do is show you one approach…to solving this.…Again, this is my approach…and it might look a little different than yours.…The first thing that I would do would be…to declare my variables.…There's quite a few in this program.…Let's make them doubles…and I'm gonna start by declaring the width for the house…so I'm gonna make a w, the length L,…and the height, H.…
Next, I'm gonna take care of my windows.…Again, I use double.…We'll call it numWin to represent the number of windows…and I need to know the window width…and the window height.…We need to do the same thing with the doors.…Double numDoors, doorWidth, and doorHeight…because we don't need paint for the doors or the windows.…So, when we calculate our final surface area…we're gonna subtract these values.…Remember, our goal is to find the total surface area…that needs to be painted…so I am gonna go ahead…
