字符串轉化類Conversion.java源代碼如下：*****************************************************************
import?java.util.Scanner;
public?class?Conversion?{
public?static?void?main(String[]?args)?{ Scanner?sc?=?new?Scanner(System.in); System.out.println("輸入："); Integer?n?=?Integer.valueOf(sc.nextLine()); String[]?ins?=?new?String[n]; for?(int?i?=?0;?i?<?n;?i++)?{ins[i]?=?sc.nextLine().trim();
ins[i]?=?reverse(ins[i]);
} System.out.println("輸出："); for?(String?s?:?ins)?{System.out.println(s);
} } public?static?String?reverse(String?in)?{ byte[]?b?=?in.getBytes(); for?(int?i?=?0;?i?<?b.length;?i++)?{if?((b[i]?>=?65)?&&?(b[i]?<=?77))?{
