总结两个向量

Question

我可以知道如何在java中对两个向量求和吗？

public void CosineSimilarity(ArrayList<Integer> h,String a, Object[] array) throws Exception { 
           Vector value  = new Vector();
           double cos_sim=(cosine_similarity(vec1,vec2))*60/100;
           System.out.println(cos_sim); //I get [0.333] and [0.358]
           value.add(cos_sim);   
           CompareType(value,a,array);
}

这里是CompareType函数

 public void CompareType(Vector value,String a,Object[] array ) throws Exception {
                // TODO Auto-generated method stub
                String k;
                double c = 0;
                String sql="Select Type from menu ";
                DatabaseConnection db = new DatabaseConnection();
                Connection  conn =db.getConnection();
                PreparedStatement  ps = conn.prepareStatement(sql);
                ResultSet rs = ps.executeQuery();
                Vector value1 = new Vector();
                while (rs.next()) 
                {
                k=rs.getString("Type");
                if(a.equals(k))
                {
                    c=10.0/100;
                    value1.add(c);
                    }
                else
                {
                    c=0;
                    value1.add(c);  
                }
                 }
                System.out.println(value1); // I get [0.0] and [0.1]
                Sum(value,value1);

                ps.close();
                rs.close();
                conn.close();

            }

我应该在下面的函数中写什么，这样可以将两个值向量相加并返回两个总值？

private void Sum(Vector value, Vector value1) {

        // TODO Auto-generated method stub

    }
