返回数组的函数：向量的加法

public class Main {/* 来 自 N  o w  J a v a . c o m*/


  static int[] VectorAddition(int[] u, int[] v) {

    int[] result = new int[u.length];


    for (int i = 0; i < u.length; i++)

      result[i] = u[i] + v[i];


    return result;

  }


  public static void main(String[] args) {

    int[] x = { 1, 2, 3 };

    int[] y = { 4, 5, 6 };

    int[] z = VectorAddition(x, y);
