一、题目描述
题目和要点：
1、中文大写金额数字前应标明“人民币”字样。中文大写金额数字应用壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、佰、仟、万、亿、元、角、分、零、整等字样填写。
2、中文大写金额数字到“元”为止的，在“元”之后，应写“整字，如￥ 532.00应写成“人民币伍佰叁拾贰元整”。在”角“和”分“后面不写”整字。
3、阿拉伯数字中间有“0”时，中文大写要写“零”字，阿拉伯数字中间连续有几个“0”时，中文大写金额中间只写一个“零”字，如￥6007.14，应写成“人民币陆仟零柒元壹角肆分“。
二、代码
import java.util.Scanner; public class Main { public static void main(String []args){ Scanner sc=new Scanner(System.in); while(sc.hasNext()){ double n=sc.nextDouble(); System.out.println(change(n)); } } public static String change(double n){ StringBuffer result = new StringBuffer(""); String str = String.valueOf(n); String[] arr = str.split("\\."); String[] arr1 = arr[0].split(""); String[] arr2 = arr[1].split(""); if(!(arr1.length == 1 && arr1[0].equals("0"))){ for(int i = 0; i < arr1.length; i++){ String s = getUnit(arr1[i],arr1.length - i); if(s.equals("零")){ if(i == arr1.length - 1){ result.append("元"); }else if(!arr1[i + 1].equals("0")){ result.append(s); } }else{ result.append(s); } } } if(arr1.length == 2 || arr1.length == 6 || arr1.length == 10){ result = new StringBuffer(result.substring(1)); } String jiao = arr2[0]; String fen = "0"; if(arr2.length != 1){ fen = arr2[1]; } if(jiao.equals("0") && fen.equals("0")){ //都为0为整 result.append("整"); }else{ //其他则加小数 jiao = getUnitArr2(jiao); fen = getUnitArr2(fen); if(!jiao.equals("0")){ result.append(jiao + "角"); } if(!fen.equals("0")){ result.append(fen + "分"); } } StringBuffer qz = new StringBuffer("人民币"); result = qz.append(result); return result.toString(); } private static String getUnitArr2(String s) { String s1 = s; switch (Integer.valueOf(s)){ case 1: s1 = "壹";break; case 2: s1 = "贰";break; case 3: s1 = "叁";break; case 4: s1 = "肆";break; case 5: s1 = "伍";break; case 6: s1 = "陆";break; case 7: s1 = "柒";break; case 8: s1 = "捌";break; case 9: s1 = "玖";break; } return s1; } public static String getUnit(String s,int i){ String s1 = ""; String s2 = ""; switch (i){ case 1: s2 = "元";break; case 2: s2 = "拾";break; case 3: s2 = "佰";break; case 4: s2 = "仟";break; case 5: s2 = "万";break; case 6: s2 = "拾";break; case 7: s2 = "佰";break; case 8: s2 = "仟";break; case 9: s2 = "亿";break; case 10: s2 = "拾";break; case 11: s2 = "佰";break; case 12: s2 = "仟";break; } switch (Integer.valueOf(s)){ case 1: s1 = "壹";break; case 2: s1 = "贰";break; case 3: s1 = "叁";break; case 4: s1 = "肆";break; case 5: s1 = "伍";break; case 6: s1 = "陆";break; case 7: s1 = "柒";break; case 8: s1 = "捌";break; case 9: s1 = "玖";break; case 0: return "零"; } return s1 + s2; } }
