このインスタンスでdo-whileループを停止する方法

Question

ここにコードがあります。入力された辺のすべて3つが0で、1または2だけでなく、ループを停止できるようにする必要があります。入力された辺の1つまたは2つが0の場合、ユーザーにもう一度プロンプトが表示されます。すべての3つの条件が満たされたときにプログラムを終了する演算子はありますか？

ありがとうございます！

状態ならば、すべての3が0 が {// ゲット側面 System.out.printを（「三角形の辺1を入力してください。」）を実行しているかどうかを確認するために別のものを追加します。 side1 = key.nextInt（）; System.out.print（ "三角形の2辺を入力してください："）; side2 = key.nextInt（）; System.out.print（ "三角形の3辺を入力："）; side3 = key.nextInt（）;

 double longest = 0; 
     double shorter1 = 0; 
     double shorter2 = 0; 
     if (side1 == 0 && side2 == 0 && side3 == 0){ 
       break;

     if (side1 == 0 || side2 == 0 || side3 == 0)
