收集这道题目原因是以前做过,但是实现的很麻烦,这次看到别人写的感觉简单易懂。
从一个pdf看到,出处就不贴了 = 。=
public class RenMingBi { private static final char[] data = new char[] { '零', '壹', '贰', '叁', '肆',
'伍', '陆', '柒', '捌', '玖' };
private static final char[] units = new char[] { '元', '拾', '佰', '仟', '万',
'拾', '佰', '仟', '亿','拾', '佰', '仟'}; // 简单那整数 int:-2147483648~2147483647
public static String convert(long money) {
StringBuffer sbf = new StringBuffer(40);
int unit = 0;
while (money != 0) {
sbf.insert(0,units[unit++]);
int number = (int) money % 10;
sbf.insert(0, data[number]);
money /= 10;
}
// System.out.println(sbf.toString());
return sbf.toString().replaceAll("零[拾佰仟]", "零").replaceAll("零+亿","亿").replaceAll("零+万", "万")
.replaceAll("零+元", "元").replaceAll("零+", "零").replaceAll("亿万", "亿");
}
//复杂带小数 long :-2^63 +2^63-1
public static String convert(double value) {
long midVal = (long) (value * 100);
String valStr = String.valueOf(midVal); // 转化成字符串
String rail = valStr.substring(valStr.length() - 2); // 取小数部分 long preint = (midVal / 100);
String prefix = convert(preint);
String suffix = "";
// 处理小数点后面的数
if (rail.equals("00")) {
suffix = "整";
} else {
suffix = data[rail.charAt(0) - '0'] + "角" + data[rail.charAt(1) - '0'] + "分";
}
return prefix + suffix; // 返回正确表示
} public static void main(String[] args) {
System.out.println(convert(2000000007));
System.out.println(convert(2000000007.211));
} }
