本文介绍了一个使用Java实现的简单程序，该程序可以将整数转换为对应的罗马数字表示形式。通过定义一个二维字符串数组来对应各个位数上的罗马数字，并利用简单的数学运算确定每个位数上应该使用的罗马数字。

import java.util.Scanner;

public class Main {

   public static void main(String[] args) {
       // TODO Auto-generated method stub
      Scanner a=new Scanner(System.in);
      String[][] lm= {
              {"","I","II","III","IV","V","VI","VII","VIII","IX"},
              {"","X","XX","XXX","XL","L","LX","LXX","LXXX","XC"},
              {"","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"},
              {"","M","MM","MMM"}
   };
    int m=a.nextInt();
    StringBuffer b=new StringBuffer();
    b.append(lm[3][m/1000%10]);
    b.append(lm[2][m/100%10]);
    b.append(lm[1][m/10%10]);
    b.append(lm[0][m%10]);
    System.out.println(b);

}
}
