Converting CSV File To Array

There is a csv file that contain 10 rows and two columns. I want to convert this csv file to array. Each cell contains several line of string. But the output is wrong. After printing output, each cell of array contains a line of one cell of csv file.

for example csv file contain

book, this book is good. that book is good.
cook, cooking is enjoyable.

After printing output of array:

book,this one is good
that book is good, null

what is wrong with this code?

Code is :

public static void main(String[] args) throws Exception {
Scanner main = new Scanner(new File("C:UsersaDesktopook1.csv"));
int line=0;
String [][] temp1=new String [10][2];
while (main.hasNext()) {
temp1[line]=main.nextLine().split(",");
line++;
}
}
