More than one return parameters

When we need more than one return parameters##

Method 1

使用容器：
Vector, HashSet, HashMaq and so on

Method 2

将返回值当做参数传入
例如：

  import java.util.HashSet;
  
  public class Return {
      
      public static void main(String[] args) {

            HashSet<Integer> set = new HashSet<Integer>();
            Alphabet alphabet = null;
            Integer a = new Integer(1);
            Double b = new Double(2.0);
            int c = 3;
            System.out.println("Before~~~");
            System.out.println("Set:"+set.size());
            System.out.println("a: "+a);
            System.out.println("b: "+b);
            System.out.println("c: "+c);
            myReturn(set, alphabet, a, b, c);
            System.out.println("After~~~");
            System.out.println("Set:"+set.size());
            System.out.println("a: "+a);
            System.out.println("b: "+b);
            System.out.println("c: "+c);
        }

      public static void myReturn(HashSet<Integer> set, Alphabet alphabet, Integer a, Double b, int c){

            set.add(new Integer(2));
            alphabet = new Alphabet();
            a = new Integer(3);
            b++;
            c++;
        }

  }
