public class EmptyStatement
extends StatementRepresents an empty statement that performs no operation. An empty statement is a valid statement that can appear wherever a statement is expected but has no executable code. Empty statements are often used as default cases or as placeholders in control flow structures.
An immutable singleton INSTANCE is provided for use when source position or other occurrence-specific metadata is not needed. Using the singleton reduces memory overhead.
