java编程 数字转换成汉字

我自己写的，匆忙写的。我有时间再改进改进。

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.util.HashMap;

import java.util.Stack;

/*

* 本程序

*/

public class Transfer {

public StackInteger transfer(int n){

StackInteger st = new StackInteger();

int division = 0; //余数

while(n=10){

division = n%10;

st.push(division);

n = n/10;

}

st.push(n); //将最高位压栈

return st;

}

public static void main(String[]args){

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

String in = "";

try {

in = reader.readLine();

} catch (IOException e) {

e.printStackTrace();

}

int n = 0;

try{

n = Integer.parseInt(in);

} catch(NumberFormatException e){

e.printStackTrace();

}

Transfer tf = new Transfer();

StackInteger s = tf.transfer(n);

/*

while(!s.empty()){

System.out.print(s.pop()); //测试语句

}

*/

HashMapInteger, String hp1 = new HashMapInteger, String(); //第一个映射表

hp1.put(0, "零"); //根据所在位的数值与中文对应

hp1.put(1, "一");

hp1.put(2, "二");

hp1.put(3, "三");

hp1.put(4, "四");

hp1.put(5, "五");

hp1.put(6, "六");

hp1.put(7, "七");

hp1.put(8, "八");

hp1.put(9, "九");

HashMapInteger, String hp2 = new HashMapInteger, String(); //第二个映射表

hp2.put(2, "十"); //根据所在位数，与中文对应

hp2.put(3, "百");

hp2.put(4, "千");

hp2.put(5, "万");

hp2.put(6, "十万");

hp2.put(7, "百万");

hp2.put(8, "千万");

hp2.put(9, "亿");

//System.out.println(s.size());

String out = "";

while(!s.isEmpty()){

int temp = s.pop();

if(s.size()==0){

if(temp !=0){

out = out + hp1.get(temp);

}

}

else{

if(temp==0){

out = out + hp1.get(temp);

}

else{

out = out + hp1.get(temp) + hp2.get(s.size()+1);

}

}

}

System.out.println(out);

}

}

对于如2008之类的数，输出的是二千零零八，还需要加以判断，我再去处理下。

还有涉及万以上的数，比如

123456

输出的是一十万二万三千四百五十六，也必须增加判断。

使用Java程序如何让阿拉伯数字转换成中文?

import java.util.Scanner;

public class Num

{

public Num() {}

static String []bigNum={"零","一","二","三","四","五","六","七","八","九"};

static String getNUM(String str)

{

int t=Integer.parseInt(str);

return bigNum[t];

}

public static void main(String[] args)

{

try

{

String strbig=new String("");

System.out.print("请输入数字：");

Scanner sc=new Scanner(System.in);

long num=sc.nextLong();

String temp=String.valueOf(num);

int b=temp.indexOf(".");

int s=temp.length()-(b+1);

int j=b;

for (int i =0; ib;i++) {

strbig+=getNUM(temp.substring(i,i+1));

j--;

}

temp=temp.substring(b+1,temp.length());

for (int i = 0; i s; i++)

{

strbig+=getNUM(temp.substring(i,i+1));

}

System.out.println("转换结果："+strbig);

}

catch(Exception ex)

{

System.out.println("请输入整数");

}

}

}

java数字转换汉字

25187是汉字‘扣’的字符编码。

每一个汉字，字母，标点符号都有自己的字符编码。

你看这个地址里的表就明白了。键盘上你按住alt键，在先键盘（数字区）输入对应的数字，显示出来的也是数字代码对应的字符。

比如：在能输入文字的地方：按住alt，在小键盘（数字区）上依次按下3,5放开所有键，你看到光标处显示的是‘#’

如何在java中将汉字输出成数字

java 中将数字变成字符输出常用的有两种方法:

第一种,直接使用系统强制类型转换进行输出.

例:

1

2

int i = 1;

System.out.println(i + "");

第二种,使用字符串 String 的 valueOf() 方法进行转换输出.

例:

1

2

int i = 1;

System.out.println(String.valueOf(i));

java怎么把字符转换成数字？

下面这个方法可以转换，前提是你的字符内容是数字类型。比如 String str = "123" 或者 char str = '2'\x0d\x0a\x0d\x0achar a = '1';\x0d\x0aString b = String.valueOf(a);\x0d\x0aint c = Integer.parseInt(b);\x0d\x0a\x0d\x0a上面你说的 c - '0' 这一步应该就是转换格式的 ，我知道类似的在 js 中把一个变量转换成字符串 可以用 var str = str+""; 加两个引号就相当于格式转换了。
