JAVA: VarArgs add variables -

JAVA: VarArgs add variables -

i have method:

public static double[] averages(double[]... input) { double[] result = new double[input.length]; for(int = 0; i< result.length; i++) { result[i] = arrays.stream(input[i]).average().getasdouble(); } homecoming result; }

i not know priori how many double arrays should switch method. how can add together method variable double [] loop?

in case i:

arraylist<double[]> sim=new arraylist<double[]>(); arrays.add(new double[]{0.25,0.97,0.47,0.31,0.71}); arrays.add(new double[]{0.51,0.91,0.88,0.12,0.15}); arrays.add(new double[]{0.47,0.71,0.42,0.17,0.71}); arrays.add(new double[]{0.41,0.55,0.53,0.64,0.81}); arrays.add(new double[]{0.91,0.14,0.71,0.11,0.61});

but unfortunately, not know arrays double[] before running program.

should go method averages() 5 double arrays nowadays in arraylist "sim"

i should this:

averages(arrays.get(0),arrays.get(1),arrays.get(2),arrays.get(3),arrays.get(4))

but content dell'arraylist "sim" not know prior execution!

first, made typo, didn't mean:

sim.add(new double[]{0.25,0.97,0.47,0.31,0.71});

would made much more sence.

then can phone call method follows:

double[] results = averages(sim.toarray(new double[]{}));

i didn't seek run though, new arrays there because method toarray() returns object[] , not t[] reason.
