◦ x.getLength(0)

Question 2

Analyze the following code:

ArrayList list = new ArrayList();
list.add("Beijing");

list.add("Shanghai");
list.set(3, "Hong Kong");

◦ If you replace the last line by list.add(3, "Hong Kong"), the code will compile and run fine.
◦ The last line in the code causes a runtime error because there is no element at index 3 in the array list.
◦ The last line in the code has a compile error because there is no element at index 3 in the array list.
