简单巧妙的罗马数字转换方法

java
public String IntToRoma(int num){

 int[] values={1000,900,500,400,100,90,50,40,10,9,5,4,1}; String[] strs={"M","CM","D","CD","C","XC",                "L","XL","X","IX","V","IV","I"}; StringBuilder sb = new StringBuilder(); for(int i=0;i<values.length;i++) {    while(num >= values[i]) {        num -= values[i];        sb.append(strs[i]);    } } return sb.toString();

}
