在这个颜值当道，屌丝闪边的时代，拼不过颜值拼内涵，只有知识丰富才能提升一个人的内在气质和修养，所谓人丑就要多学习，今天给大家分享java实现整数转化为中文大写金额的方法，希望可以对大家能有小小的帮助。
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：
private static String getNumberStr1000 (int num) { if (num 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) { (); (); } //百 if (b 0) { (); (); } else { if (q != 0) {(); } } //十 if (s 0) { (); (); } else { if (b != 0) {(); } } //个 if (g 0) { (); } return (); }
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：
public static String getNumberStr(int num) { if (num 0) { return ""; } if (num == 0) { return NUMBER1[0]; } int split = 10000; int y = num / (split * split); int w = (num / split) % split; int g = num % split; StringBuffer sb = new StringBuffer(); //亿 if (y 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(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(getNumberStr1000(g));} } else {if (y != 0) { ();}sb.append(getNumberStr1000(g)); } } return (); }
