De instructie continue wordt gebruikt in de lusbesturingsstructuur wanneer u onmiddellijk naar de volgende iteratie van de lus moet springen. Het kan worden gebruikt met een for-lus of while-lus.
De Java vervolg verklaring wordt gebruikt om de lus voort te zetten. Het zet de huidige stroom van het programma voort en slaat de resterende code bij de opgegeven voorwaarde over. In het geval van een binnenlus wordt alleen de binnenlus voortgezet.
We kunnen de Java continue-instructie gebruiken in alle soorten lussen, zoals for loop, while loop en do-while loop.
Syntaxis:
jump-statement; continue;

Zoals je in de bovenstaande uitvoer kunt zien, wordt 5 niet op de console afgedrukt. Dit komt omdat de lus wordt voortgezet wanneer deze 5 bereikt.
Java Continue-instructie met binnenlus
De binnenste lus wordt alleen voortgezet als u de instructie continue binnen de binnenste lus gebruikt.

Java Continue-instructie met gelabeld For Loop
We kunnen de continue-instructie met een label gebruiken. Deze functie is geïntroduceerd sinds JDK 1.5. We kunnen nu dus elke lus in Java voortzetten, of het nu een buitenste lus of een binnenste lus is.
