What will be the output of the program?
import java.util.*;
public class Demo25
{
public static void main(String[] args)
{
List<String> a = Arrays.asList("x", "y");
List<String> b = Arrays.asList("y", "x");
System.out.println(a.equals(b));
}
}
Answer: A
List equality is defined by order as well as contents: two lists are equal only when the elements at each position match. Reversing them therefore makes the lists unequal. A Set comparison of the same two collections would have been true, since a Set has no positions.
