Question

I want to create an ArrayList<Float> of length 350. I did this:

x = new ArrayList<Float>(350);

No i want this array to have ‘zero’ float value at each point. i can do this:

for (int i = 0; i< 350 ; i++){
            x.add((float) 0.0);
}

So my question is if there is another way to do the same thing without iterating. I want minimum iterating to increase efficiency.

Answer 1

If you want efficiency I wouldn’t use ArrayList or Float here. I wouldn’t recommend using float even as it’s precision is so poor, unless you really know what you are doing.

I suggest you use an array of double.

double[] x = new double[350]; // all 0.0
