今天去面試卻遇到了這樣一道題“如何將字符串或者數(shù)字轉(zhuǎn)換成大寫(xiě)貨幣”，當(dāng)時(shí)沒(méi)有做出來(lái)，很氣憤，于是就在網(wǎng)上查涉及如何將字符串或者數(shù)字轉(zhuǎn)換成大寫(xiě)貨幣的方法，終于找出了如何做的方法^_^

主要功能：

1.???String convertToCapitalMoney(String moneyStr)?
??????將字符串轉(zhuǎn)換成中文的大寫(xiě)貨幣值

2.???String convertToCapitalMoney(double moneyValue)
??????將數(shù)字轉(zhuǎn)換成中文的大寫(xiě)貨幣值

文件：MoneyConvert.java

???? ?Result = Result + tempCapital + tempUnit;???

}

測(cè)試代碼：

?public static void main(String[] args) {
?
??? ?String money1 = MoneyConvert.convertToCapitalMoney("33333.214");
??????? System.out.println(money1);
??????? String money = MoneyConvert.convertToCapitalMoney(33333.214);
??????? System.out.println(money);
}

輸出結(jié)果：

叁萬(wàn)叁仟叁佰叁拾叁圓貳角壹分
叁萬(wàn)叁仟叁佰叁拾叁圓貳角壹分
