java阿拉伯数字转中文数字

本文实例为大家分享了java阿拉伯数字转换成中文数字的具体代码，供大家参考，具体内容如下

package org.lulu.learn.work;

import java.io.*;

/**

public class Work02 {
 public static void main(String[] args) {
//  int num = 0;
//  System.out.println(tranWan(num));

  try(BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("res/data.txt")));
   BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("res/result.txt")))
    ){

   String str = "";
   int percent = 0;

   while ((str = br.readLine()) != null) {
    bw.write(tranWan(Integer.parseInt(str)));
    bw.newLine();
    percent++;

    Thread.sleep(100);

    System.out.print("\r[");
    for (int i = 0; i < 20; i++) {
     if(i < percent/5){
      System.out.print("=");
     }else if(i == percent/5){
      System.out.print(">");

   }


  } catch (FileNotFoundException e) {

  } catch (IOException e) {

 }
}

再为大家分享一段：java实现阿拉伯数字转换为汉字数字

private static String toChinese(String str) {
  String[] s1 = { "零", "一", "二", "三", "四", "五", "六", "七", "八", "九" };
  String[] s2 = { "十", "百", "千", "万", "十", "百", "千", "亿", "十", "百", "千" };
  String result = "";
  int n = string.length();
  for (int i = 0; i < n; i++) {
   int num = string.charAt(i) - '0';
   if (i != n - 1 && num != 0) {
    result += s1[num] + s2[n - 2 - i];
   } else {
    result += s1[num];
   }
   System.out.println(" "+result);
  }
  System.out.println(result);
  return result;
 }

 public static void main(String[] args) {
  Scanner scanner = new Scanner(System.in);
  System.out.println("输入字符串：");
  String str = scanner.next();
  // 将字符串数字转化为汉字
  toChinese(str);
 }
