# Interface IncrementInstruction

All Superinterfaces:
  `ClassFileElementPREVIEW`, `CodeElementPREVIEW`, `InstructionPREVIEW`

public sealed interface IncrementInstruction extends InstructionPREVIEW
`IncrementInstruction` is a preview API of the Java platform.
Programs can only use `IncrementInstruction` when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Models a local variable increment instruction in the `code` array of a `Code` attribute. Corresponding opcodes will have a `kind` of `Opcode.Kind.INCREMENT`PREVIEW. Delivered as a `CodeElement`PREVIEW when traversing the elements of a `CodeModel`PREVIEW.
