Question

The output from the following code is __________.

ArrayList list = new ArrayList();
list.add("New York");
ArrayList list1 = list;
list.add("Atlanta");
list.add("Dallas");
System.out.println(list1);


A. [New York]
B. [New York, Atlanta]
C. [New York, Atlanta, Dallas]
D. [New York, Dallas]

Answer 1

The output from the code is [New York, Atlanta, Dallas].

Step-by-step explanation:

The output from the code is [New York, Atlanta, Dallas]. In the code, an ArrayList called 'list' is created and the string 'New York' is added to it. Then, another ArrayList called 'list1' is created and assigned to the same memory location as 'list'. So, any changes made to 'list' will also be reflected in 'list1'.

The code then adds the strings 'Atlanta' and 'Dallas' to 'list'. When 'list1' is printed using the System.out.println() method, it will display the elements of 'list', which are 'New York', 'Atlanta', and 'Dallas'.
