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(">");
     }else{
      system.out.print(" ");
     }

    }

    system.out.printf("\t%.2f%%", (float)percent);
   }

}

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);
 }
