Where is the a and b coming from? Is that some lambda specific stuff? Seems like a and b need to be defined in order for this to work?

What will be the output of the following code?
--------------------
public static void main(String[] args) {
List<Integer> list = Arrays.asList(1, 2, 3, 4, 5);
list.sort((a, b) -> b - a);
System.out.println(list);
}
