Vector of vector...

[lokesh rajarathnam]

Hi...

I need to know how to add an vector to another vector.

Issue...
The text file contains N number of lines and each line contains 12 number of words. I need to store an 12 words(one line)in vector after that
the vector will be stored into another new vector.

I will able to do split the line into words...

any help please...

The add(E o) method will do this.

Why have you decided to use a Vector? Normally there isn't a good reason to use this class.

Why aren't you using a String[][]?

As Paul has suggested, ArrayList<String> and ArrayList<ArrayList<String>> are better implementations.

That's never a good solution. Use ArrayList<List<String>>. That can still store ArrayList<String>, but also LinkedList<String> if needed.

The declaration and initialization would be
<blockquote>code:

---

<pre name="code" class="core">List<List<String>> list = new ArrayList<List<String>>();
list.add(new ArrayList<String>());</pre>

---
