java实现整数转化为中文大写金额的方法

前端之家收集整理的这篇文章主要介绍了java实现整数转化为中文大写金额的方法前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

在日常生活中,我们经常会将阿拉伯数字转化为中文大写的情况:"零","壹","贰","叁","肆","伍","陆","柒","捌","玖","拾","佰","仟","万","亿",因此自己就编写一个类,实现该功能的转化。

实现过程:

对于这个问题的实现,我们首先把数字按四位一个拆开(符合我们读数字的习惯),然后对这四位数,做出他的读法,具体代码如下:

9999 || num < 0) { return ""; } int q = num / 1000; int b = (num / 100) % 10; int s = (num / 10) % 10; int g = num % 10; StringBuffer sb = new StringBuffer(); //千 if (q > 0) { sb.append(NUMBER1[q]); sb.append(NUMBER2[3]); } //百 if (b > 0) { sb.append(NUMBER1[b]); sb.append(NUMBER2[2]); } else { if (q != 0) { sb.append(NUMBER2[0]); } } //十 if (s > 0) { sb.append(NUMBER1[s]); sb.append(NUMBER2[1]); } else { if (b != 0) { sb.append(NUMBER2[0]); } } //个 if (g > 0) { sb.append(NUMBER1[g]); } return sb.toString(); }

下面我们只需要在编写一个方法,实现每个四位数的读法以及对应的单位即可,具体代码如下:

0) { sb.append(getNumberStr1000(y)); sb.append(NUMBER2[5]); } //万 if (w > 999) { sb.append(getNumberStr1000(w)); sb.append(NUMBER2[4]); } else { if (w > 0) { if (y != 0) { sb.append(NUMBER2[0]); } sb.append(getNumberStr1000(w)); sb.append(NUMBER2[4]); } } //万以下 if (g > 0) { if (w != 0) { if (g > 999) { sb.append(getNumberStr1000(g)); } else { sb.append(NUMBER2[0]); sb.append(getNumberStr1000(g)); }

} else {
if (y != 0) {
sb.append(NUMBER2[0]);
}
sb.append(getNumberStr1000(g));
}
}
return sb.toString();
}
