Question

I have two Arrays that are initialized as such:

    public static double[] arrayweight= new double[100];
    public static double[] arraypulse= new double[100];

They are filled with data e.g. 23.0,25.8….etc.

I need to combine the two Arrays into one array of double[]

I have chosen to use the following approach which does not work. Any ideas?

     ArrayList <Double> al = new ArrayList<Double>();

// The following methods do not work ;(     
     al.add((double[]) Global.arrayweight);
     al.add(new Double(Global.arraypulse));

I like Nammari’s answer best, but just in case you are not using Commons Lang and want to stick with pure Java:

double[] result = Arrays.copyOf(Arrayweight, Arrayweight.length + Arraypulse.length);
System.arrayCopy(Arraypulse, 0, result, Arrayweight.length, Arraypulse.length);
