How to clear Vector of arrays???

I have a vector data that has arrays, I want to clear it when I test it
if it's not empty this is what I did :

if(!data.isEmpty()){
for(int i = 0; i < V_size; i++)
data.setElementAt(null,i); }



But it does not work, please help

how about Vector.removeAllElements() ?

Simple solution.

data.clear();

This will clear the vector for you
