java飛行機着座チャートアレイ

Question

2次元配列に問題があり、正しく出力されないため、プログラムが正常に動作していますが、飛行機着座チャートを水平に出力するケース4を選択すると、 。もし誰かが正しい方向に私を指すことができればそれはすばらしいでしょう！

プレーンの行と列を画面の行と列に混在させています。

あなたの水平出力は本当に複雑です。これは、垂直出力と同じくらい簡単でなければなりません。キーは垂直出力のコードを複製しますが、2つのforステートメントを逆にします。

for(int j = 0; j < 3; ++j) { 
    for(int i = 0; i < 10; ++i) { 

魔法のように動作します。

まあ、ほとんど仕事。これは、平面の左右を反転させます。最初のループを少し変更すれば、それも修正されます。生徒に残された
