continue ステートメントは、ループの次の繰り返しにすぐにジャンプする必要がある場合に、ループ制御構造で使用されます。 for ループまたは while ループと一緒に使用できます。
ジャワ 継続ステートメント ループを継続するために使用されます。プログラムの現在のフローを継続し、指定された条件で残りのコードをスキップします。内側のループの場合は、内側のループのみを継続します。
Java の continue ステートメントは、for ループ、while ループ、do-while ループなど、あらゆるタイプのループで使用できます。
構文：
jump-statement; continue;
Java Continue ステートメントの例

内部ループ内で continue ステートメントを使用した場合にのみ、内部ループが続行されます。

ラベル付きの continue ステートメントを使用できます。この機能は JDK 1.5 以降に導入されました。したがって、Java では、外側のループであっても内側のループであっても、ループを続行できるようになりました。
