    Instances newData = init;
    Scanner s = new Scanner(System.in);
    Double in;/*from   w ww  .ja v  a  2s . c o  m*/
    System.out.println("Jumlah Atribut : " + (nAttributes - 1));

    for (int i = 1; i <= nAttributes - 1; i++) {
        //Attribute a = train.attribute(i - 1);
        System.out.print("Attribute " + i + " : ");
        in = s.nextDouble();
        ins.setValue(i, in);
        //newIns[i] = in;
    }
    newData.add(ins);
    double nomorKelas = classifyInstance(newData.lastInstance());
    return init.attribute(init.numAttributes() - 1).value((int) nomorKelas);
