Answer 1

public class Predction implements Function<Double[], Double> {
   private final double[] t_vector;


   Predction(double[] t_vector) {
      this.t_vector = Arrays.copyOf(t_vector, t_vector.length);
   }


   public Double apply(Double[] f_vector) {
      assert f_vector[0] == 1.0;
      double predc = 0;
      for (int j = 0; j < t_vector.length; j++) {
         predc += t_vector[j] * f_vector[j];
      }
      return predc;
   }
