一个JAVA问题,怎么考虑零处理问题?
题目：使用Java语言实现输入人民币小写金额，输出相对应的人民币大写金额的功能。
要求：
使用Java语言。
无需使用数据库。
输入界面和显示界面自定义。
输入方式和显示方式自定义。
输入人民币小写金额最高9,999,999,999,999.99。
输入人民币金额最低0.01。
人民币大写内容为：零、壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、佰、仟、万、亿。
人民币单位：分、角、圆。
当输入小写金额没有分、角时需要在大写金额后添加“整”。
例子：
输入：100.00
输出：壹佰圆整
输入：0.01
输出：壹分
输入：9,999,999,999,999.99
输出：玖万玖仟玖佰玖拾玖亿玖仟玖佰玖拾玖万玖仟玖佰玖拾玖圆玖角玖分
输入：1500.08
输出：壹仟伍佰圆零捌分
输入：200.23
输出：贰佰圆贰角叁分
