Ok. I have written a code and it works as I want it to. Can you please tell me if there are any better ways of doing it?

for #1, I did

Code:

arrOfArr.add(arr);
String tempStr[] = (String[])arr.toArray(new String[arr.size()]);
arr = new ArrayList<String>( Arrays.asList(tempStr));

This solved the problem of arrOfArr getting deleted when arr.remove() was used to delete elements.



for #2, I did

Code:

String[][] dataOutput = new String[row][col];
for(i=0; i<row; i++)
{
        tempArr = arrOfArr.get(i);
	tSize = tempArr.size();
	for(j=0; j<tSize; j++)
	{
	        dataOutput[i][j]=tempArr.get(j).toString();
	}				
}

This helped me convert ArrayList of Arraylists to String[][]
