如何实现二维向量

核心提示：可以这样: Vector vector1=new Vector(); Vector vector2=new Vector(); ... .. HashTable numbers=new HashTable(); numbers.put("vector1",vector1); numbers.put(

　　可以这样:
Vector vector1=new Vector();
Vector vector2=new Vector();
...
..
HashTable numbers=new HashTable();
numbers.put("vector1",vector1);
numbers.put("vector2",vector2);
...
..
