What is the output of the following code snippet?
Public static int check(ArrayList<Integer> listData)
{
Int sum = 0;
For (int i = 0; i < listData.size() ; i++)
{
Sum = sum + listData.get(i) ;
}
Return sum;
}
Public static void main(String[] args)
{
ArrayList<Integer> vdata = new ArrayList<Integer>() ;
Int rsum;
For (int cnt = 0; cnt < 3; cnt++)
{
Vdata.add(cnt + 1) ;
}
Rsum = check(vdata) ;
System.out.println(rsum) ;
}

The check method takes an ArrayList of integers as input and returns the sum of all values in the list.

In the main method, an ArrayList vdata is created and populated with the values 1, 2, and 3. Then, the check method is called with vdata as the argument, and the returned value is stored in rsum.

Since the sum of 1, 2, and 3 is 6, the output of the program will be 6. Therefore, the correct option is D.
