La instrucció continue s'utilitza a l'estructura de control de bucle quan necessiteu saltar immediatament a la següent iteració del bucle. Es pot utilitzar amb bucle for o bucle while.
El Java continuar declaració s'utilitza per continuar el bucle. Continua el flux actual del programa i salta el codi restant en la condició especificada. En el cas d'un bucle intern, només continua el bucle intern.
Podem utilitzar la instrucció de continu de Java en tot tipus de bucles, com ara bucle for, bucle while i bucle do-while.
Sintaxi:
jump-statement; continue;
Exemple de declaració Java Continue

És perquè el bucle es continua quan arriba a 5.
Declaració Java Continue amb Inner Loop
Continua el bucle intern només si feu servir la instrucció continue dins del bucle intern.

Podem utilitzar la instrucció continue amb una etiqueta. Aquesta característica s'ha introduït des de JDK 1.5. Per tant, ara podem continuar qualsevol bucle a Java, ja sigui un bucle extern o intern.
