public class Num2Rmb{

private String[] hanArr={"零","壹","贰","叁","肆","伍","陆","柒","仈","玖"};

private String[] unitArr={"拾","佰","仟"};

private String[] divide(double num){

long zheng=(long)num;
long xiao =Math.round(num-zheng)*100;
return new String[] {zheng+"",String.valueOf(xiao)};

}

private String toHanStr(String numStr){

String result="";
int numLen=numStr.length();
for(int i=0;i<numLen;i++){

//将char型的数字转换成int型数字，因为他们的ASCAII码值恰好相差48

//因此将char型的数字减去48即得到int型的数字，如'24'变成24
int num=numStr.charAt(i)-48;

//如果不是最后一位数字且数字不为0，则需添加单位（拾,佰,仟）

    if(i!=numLen-1&& num!=0){
result+=hanArr[num]+unitArr[numLen-2-i];
}
     else
{
          result+=hanArr[num];
    }
   }
return result;
}
public static void main(String[] args){
    Num2Rmb nr=new Num2Rmb();
   System.out.println(Arrays.toString(nr.divide(236711125.123)));
    System.out.println(nr.toHanStr("6109"));

}
