A. b = nf.parse(input);<br />
B. b = nf.format(input);<br />

<span style="font-size: medium;">Ans: B </span><br />
<br />
<span style="font-size:medium;"> 解說:<br />
14行插入那一行設定了b物件的值為314.159,26<br />
parse(剖析)的語意一般是從字串轉成所要的類別型態物件，如Integer.parseInt<br />
NumberFormat中的format方法是將數值以所指定的格式輸出，回傳值型態是String<br />
