Question 1

Show the output of the following code:

String[] array = {"red", "green", "blue"};
ArrayList list = new ArrayList<>(Arrays.asList(array));
list.add(0, "red");
System.out.println(list);

◦ ["red", "green", "blue"]
◦ ["red", "red", "green", "blue"]
◦ ["red", "green", "blue", "red"]
◦ ["red", "green", "red", "blue"]

Question 2

Analyze the following code:

Double[] array = {1, 2, 3};
ArrayList list = new ArrayList<>(Arrays.asList(array));
System.out.println(list);

◦ The code is correct and displays [1, 2, 3].
◦ The code is correct and displays [1.0, 2.0, 3.0].
◦ The code has a compile error because asList(array) requires that the array elements are objects.

◦ The code has a compile error because an integer such as 1 is automatically converted into an Integer object, but the array element type is Double.
