Question

In Java for [computing] please. Thanks.

Implement a method public static double[] difference(double[] vec1, double[] vec2) to compute the (component-wise) difference of vectors vec1 and vec2 as a new vector. Assume that vec1 and vec2 are of the same length. The difference of vectors (a1, a2, . . . , an) and (b1, b2, . . . , bn) is (a1 − b1, a2 − b2, . . . , an − bn). For example, the difference of (−2, −4, 9) and (3, −2, 4) is (−2 − 3, −4 − (−2), 9 − 4) = (−5, −2, 5). (7 marks)

Answer 1

Main.java

public class Main
{
   public static double[] difference(double[] vec1, double[] vec2){
   int l = vec1.length;
   double[] diff_vec = new double[l];
  
   for(int i=0; i<l; i++)
   diff_vec[i] = vec1[i] - vec2[i];
  
   return diff_vec;
   }
  
   public static void main(String[] args) {
   double[] vec1 = {-2, -4, 9};
   double[] vec2 = {3, -2, 4};
  
   double[] diff_vec = difference(vec1, vec2);
  
   System.out.print("Difference vector: ");
   for(int i=0; i<diff_vec.length; i++)
       System.out.print(diff_vec[i] + " ");
   }
}
