Using the computational language in JAVA it is possible to write a code that at least passes an unspecified number of integers

<em>for(int i=0;i<args.length;i++)</em>
<em>sum=sum+Integer.parseInt(args[i]);//converting string to integer and then adding it with sum variable and storing back in sum</em>

Answer:
b. size
Explanation:
We can use the size() method of java.util.ArrayList to determine the size of an ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.
Below is an example code to illustrate the use of the size() method of the ArrayList:-
ArrayList<Integer> aList = new ArrayList<Integer>(5);
aList.add(25);
aList.add(2);
aList.add(5);
aList.add(22);
System.out.println("Size of the array list: " + aList.size());
This will print the size of the array list as 4 since we've added four numbers into the array list.
