Explanations “Top Java Quiz Questions”

What is the result of the following?

List<String> one = new ArrayList<String>();
one.add("abc");
List<String> two = new ArrayList<>();
two.add("abc");
if (one == two)
 System.out.println("A");
else if (one.equals(two))
 System.out.println("B");
else
 System.out.println("C");

❌ A. A
✅ B. B
❌ C. C
❌ D. An exception is thrown.
❌ E. The code does not compile.

Explanation:
The first if statement is false because the variables do not point to the same object.
The second if statement is true because ArrayList implements equality to mean the
same elements in the same order.
