I have the following code snippet which implements the vector of vectors and stores values in a Hashmap like this Vector rows_ = new Vector(); Vector cols_ = null; while((row = dis.readLine())!= null) { StringTokenizer st = new StringTokenizer(row, " "); //for first row if (test==0){ while (st.hasMoreTokens()) { rrow.add(st.nextToken()); } for (Enumeration e = rrow.elements(); e.hasMoreElements();) { String myString = (String) e.nextElement(); row_name.addElement(myString); } test++; continue; } // create a new Vector for each row's columns co   More>>

I have the following code snippet which implements the vector of vectors and stores values in a Hashmap like this

```

Vector rows_ = new Vector();

Vector cols_ = null;

{

StringTokenizer st = new StringTokenizer(row, " ");

//for first row

if (test==0){

while (st.hasMoreTokens())

{

}

for (Enumeration e = rrow.elements(); e.hasMoreElements();)

{

String myString = (String) e.nextElement();

}

test++;

continue;

}

// create a new Vector for each row's columns

cols_ = new Vector();

rowlist = new Vector();

// loop through columns

while (st.hasMoreTokens())

{

}

counter = 0;

for (Enumeration e = cols_.elements(); e.hasMoreElements();)

{

String myString = (String) e.nextElement();

if (counter ==0) {

rec = myString;

counter ++;

continue;

} else {

// print(rowmap);

counter ++;

}

}

row_map.put(rec,rowlist);

// add the column Vector to the rows   Vector

test++;

}

```

rows_ is the outervector and I access each element using the following method
```

String element_ij = (String)(((Vector)(rows_.elementAt(i))).elementAt(j));

```

i was wondering how i could use the toArray method to convert this into a Double dimensional array m[][]. Thanks    <<Less

consider putting the vectors into a DefaultTableModel?
