for文中でreturnしてはならない

More than 1 year has passed since last update.

for文の中にreturnを書くと、1回しか回らない。
下のサンプルコードの
for (; ;)
は無限ループのはずだが、
returnでループが打ち切られて即終了となる。

まともなコードを書くのであれば、
returnはforの外に書く必要がある。

public class ForReturn {

    public static void main(String[] args) {
        // TODO 自動生成されたメソッド・スタブ
        String result = forReturn(2);
        System.out.println(result);
    }

    public static String forReturn(int i){
        for (; ;){
        return "不合格";
        }
    }
}
実行結果
不合格

ということを今更になって学んだ今日でした。。。。。
