Java Default Method is a method in an interface that has a body and provides a default implementation. This allows an interface to evolve over time without breaking existing implementations. Java Default Methods were introduced in Java 2014 with Java 8 to support the concept of adding new methods to interfaces in a backward-compatible manner. Default methods help ensure that older code still works while allowing newer versions of the interface to offer additional functionality.
