備忘録No.4「文字列を取得して、その周りを飾る」[Java]

Last updated at Posted at 2020-10-29

#やりたい事
1.任意の文字数の文字列を一つ受け取る
2.受け取った文字列の周囲を"+"で囲うような見た目で出力する

例.「SUN」という文字列を受け取った場合

+++++
+SUN+
+++++

#コード

        Scanner sc = new Scanner(System.in);
        String word = sc.nextLine();
        int wordNum = word.length();//単語の文字数
        int lineNum = wordNum + 2;//単語を囲うのに必要な文字数

        Character [][] plus = new Character[3][lineNum];//
        for(int i = 0; i < plus.length; i ++) {
            for(int j = 0; j < plus[i].length; j++) {
                plus[i][j] = '+';
                for(int k = 0; k < word.length(); k++) {
                    int l = k + 1;
                    plus[1][l] = word.charAt(k);//単語の文字をループで一文字ずつ抽出して、囲われるように要素を更新
                }
                System.out.print(plus[i][j]);
            }
            System.out.println("");
        }

#感想
かなりゴリ押しな作り方をしてしまっている気がする...。三重ループを使ってみた(というかなってしまった)が、こんな使い方をするのかどうかも分からず使ってしまっている。
