Are two null values 'a' and 'b' considered equal in comparison?

In the context of comparison in Android (Java or Kotlin), two null values a and b are considered equal if both are null.

For example, in Java:

String a = null;
String b = null;
boolean areEqual = (a == b); // true, since both are null

However, it is important to distinguish between reference comparison (==) and content comparison (.equals()). When comparing with null, == is usually used, as calling .equals() on null will cause an error.

Thus, two values that are null are considered equal when comparing references.
