Příkaz continue se používá ve struktuře řízení smyčky, když potřebujete okamžitě přejít na další iteraci smyčky. Lze jej použít se smyčkou for nebo while.
Java pokračování prohlášení se používá k pokračování smyčky. Pokračuje v aktuálním toku programu a přeskočí zbývající kód za zadaných podmínek. V případě vnitřní smyčky pokračuje pouze vnitřní smyčkou.
Můžeme použít příkaz Java continue ve všech typech smyček, jako je smyčka for, smyčka while a smyčka do-while.
Syntax:
jump-statement; continue;
Příklad příkazu Java Continue

Java Continue Statement with Inner Loop
Pokračuje ve vnitřní smyčce, pouze pokud použijete příkaz continue uvnitř vnitřní smyčky.

Můžeme použít příkaz continue s popiskem. Tato funkce je zavedena od verze JDK 1.5. Takže nyní můžeme pokračovat v jakékoli smyčce v Javě, ať už je to vnější smyčka nebo vnitřní.
