用java代码将阿拉伯数字金额转换成中文大写

思路：首先，利用String的特性，将金额分成整数部分和小数部分，进行分开处理，然后再用if条件进行判断，具体代码如下：

public class getChineseMoney(){
    public static void main(String srgs[]){
        System.out.println("转换之前的金额为：1824512.54");
        System.out.print("转换之后的金额为：");
        System.out.print(ChineseMoney(1824512.54)):
    }
    public static String ChineseMoney(String money){
        String text = transChineseMoney1(money) +                     transChineseMoney2(money);
        /*这里的思路是，如果金额没有小数部分，则在后面加上“零分”
        “Pattern.CASE_INSENSITIVE”的意思是不对大小写进行区分*/
        Pattern p = Pattern.compile("零分",Pattern.CASE_INSENSITIVE);
        Matcher m = p.matcher(text);         
    return text; 
    }
    /* 截取金额的整数部分，并将其转换成中文大写格式 */ 
    public static String transChineseMoney1(String s){  
        String ss = s; 
        String tmpnewchar = ""; 
//以“.”将ss分成两段,part[0]为整数部分，part[1]为小数部分
        String[] part = ss.split("\\.");  
        if (part[0].length() > 10) { // 超出可转换位数
             return"";        
        } 
        for (int i = 0; i < part[0].length(); i++) { 
            char perchar = part[0].charAt(i); 
            if (perchar == '0') 
                tmpnewchar = tmpnewchar + "零"; 
                if (perchar == '1') 
                tmpnewchar = tmpnewchar + "壹";
