Given the code fragment:
1. ArrayList<Integer> list = new ArrayList<>(1);
2. list.add(1001);
3. list.add(1002);
4. System.out.println(list.get(list.size()));
What is the result?
A.
Compilation fails due to an error on line 1.
B.
An exception is thrown at run time due to error on line 3
C.
An exception is thrown at run time due to error on line 4
D.
1002
Explanation:
The code compiles fine.
At runtime an IndexOutOfBoundsException is thrown when the second list item is added.
I think the correct answer is : A.
Because ArrayList list = new ArrayList(1);
missing “Integer” between “”
ArrayList list= new ArrayList(1);
without Integer there is a compilation error.
The correct answer is C, because list.size()=2 and ArrayList has 2 positions: 0 and 1.
You can’t execute list.get(2)because doesn’t exist that position.
