Java将数字金额转为大写中文金额
本文实例为大家分享了Java如何将数字金额转为大写中文金额的具体代码，供大家参考，具体内容如下
前言：
输入数字金额参数，运行程序得到其对应的大写中文金额；例如：输入— 12.56，输出— 12.56:壹拾贰元伍角陆分；重点来了：本人亲测有效。
奉上代码：

//小数部分的单位

//转成中文的大写金额

//beyond超出计算能力，直接返回

//判断整数部分是否存在输入012的情况

}
returnstr;
}
booleanisWan=isWan5(integerStr);//设置万单位
int[]decimals=toIntArray(decimalStr);//小数部分数字
Stringresult=getChineseInteger(integers,isWan)+getChineseDecimal(decimals);//返回最终的大写金额
if(flag){

}else{

}
}
//将字符串转为int数组

for(inti=0;i1&&integers[i+1]!=0){
key+=NUMBERS[0];
}
}

}
returnchineseInteger.toString();
