compare method Null safety

int compare (
  1. Comparable a,
  2. Comparable b
)

A Comparator that compares one comparable to another.

It returns the result of a.compareTo(b). The call may fail at run-time if a is not comparable to the type of b.

This utility function is used as the default comparator for ordering collections, for example in the List sort function.

Implementation

static int compare(Comparable a, Comparable b) => a.compareTo(b);
