Question

java 阿拉伯数字转中文小写？

例如： 12 为 十二
不用金额。

Answer 1

public class Test7 {
public static void main(String [] args){
//要输入的数字12
String i=12+"";
transition(i);
}
//阿拉伯数字转中文小写？
public static void transition(String si){
String []aa={"","十","百","千","万","十万","百万","千万","亿","十亿"};
String []bb={"一","二","三","四","五","六","七","八","九"};
char[] ch=si.toCharArray();
int maxindex=ch.length;
// 字符的转换
//两位数的特殊转换
if(maxindex==2){
for(int i=maxindex-1,j=0;i>=0;i--,j++){
if(ch[j]!=48){
if(j==0&&ch[j]==49){
System.out.print(aa[i]);
}else{
System.out.print(bb[ch[j]-49]+aa[i]);
}
}
}
//其他位数的特殊转换，使用的是int类型最大的位数为十亿
}else{
for(int i=maxindex-1,j=0;i>=0;i--,j++){
if(ch[j]!=48){
System.out.print(bb[ch[j]-49]+aa[i]);
}
}
}
}
}

输出结果：
十二

Answer 2

String[] gewei = {"一","二","三","四","五","六","七","八","九"};
String[] shiwei = {"十","百","千","万","十万","百万"};
Scanner input = new Scanner(System.in);
System.out.println("输入第一个数：");
String a = input.next();
char[] char_a = a.toCharArray();
if("0".equals(char_a[char_a.length-1]) && char_a.length == 1){
System.out.println("零");
}else{
for(int i=0; i<char_a.length; i++){
int flag = Integer.parseInt(String.valueOf(char_a[i]));
if((char_a.length-i-2) >= 0 ){
if(flag == 0 && i == (char_a.length-1)){
System.out.print("十");
}else if(flag == 0){
System.out.print("零");
}else {
System.out.print(gewei[flag-1] + shiwei[char_a.length-i-2]);
}
}else {
if(flag == 0 && i == (char_a.length-1)){
}else {
System.out.print(gewei[flag-1]);
}
}
}
System.out.println("");
}
