Java: Default Methods and Multiple Inheritance Rules
Answer
To evolve interfaces without breaking existing code.
Default methods allow interfaces to grow by adding new methods without forcing all implementing classes to provide an implementation. This supports API evolution with backward compatibility. For example, adding a 'log()' method to the 'Logger' interface can be done as a default method, so existing classes remain functional.
