Dist/Speed Function Question.

Technical Java
#1

For this year’s competition we are going to have a shooter that has a sensor that reads how far it is from the goal and then by means of a predetermined array select the appropriate speed setting.
The only problem is the set speed method requires a double and I’m not sure how to make an array of doubles.
it doesn’t seem to be simply,

double SPEED = new double];

I was wondering if I was going to have to use an ArrayList to achieve my goal.

There are two ways of doing this. If you can determine a mathematical function, use that. Otherwise, try this:


final double] SPEED = {double1, double2, double3...};

The reason your compiler didn’t like the line you posted is because of syntax. It should have looked like this:


double] SPEED = new double[size=];

I don’t recommend using an ArrayList as they use a lot more memory than you need and they require objects, not primitives.[/size]
