    输入数字输出汉字读法

    (参考:http://tieba.baidu.com/p/4101663044)

    例如,输入7865,输出:七千八百六十五

    解决一:

    (事先定义一个装有“个十百千万”,一个装有“零一二三四五.....”的数组或者集合A和B,首先获取用户输入数字的长度,然后获得各个位,每个位数就是B的下标,然后长度就是A的下标减一,比如: 485 4对应B[4]为“四”,A[2]为百 8对应B[8]为八,A[1]为十 。)

    public class Test {
    	public static void main(String[] args) throws IOException {
    		String [] A={"","十","百","千","万"};
    		String [] B={"零","一","二","三","四","五","六","七","八","九"};
    		BufferedReader buffer = new BufferedReader(new InputStreamReader(System.in));
    		String inputString = buffer.readLine();
    		//String inputString ="4859";
    		StringBuilder result= new StringBuilder();
    		int intNum= Integer.parseInt(inputString);
    		int len = inputString.length();
    		for(int i=0;i<len;i++) {
    			int yu = intNum%10;
    			result.insert(0, A[i]);
    			result.insert(0, B[yu]);
    			intNum/=10;
    		}
    		System.out.println(result.toString());
    	}
    }
    

    解决二:

    (定好模板:x万x千x百x十x,逐个提取阿拉伯数字,自右向左替换模板的x,当然阿拉伯数字还是要映射成中文,最后把替换后的模板由左数起至最后一个x的下一位截掉,剩下的就是结果)

    public class Test {
    	public static void main(String[] args) throws IOException {
    		String template= "x万x千x百x十x";
    		char[] ch=template.toCharArray();
    		char [] B={'零','一','二','三','四','五','六','七','八','九'};
    		BufferedReader buffer = new BufferedReader(new InputStreamReader(System.in));
    		String inputString = buffer.readLine();
    		//String inputString ="4859";
    		int intNum= Integer.parseInt(inputString);
    		int len = inputString.length();
    		for(int i=0;i<len;i++) {
    			int yu = intNum%10;
    			int index= template.lastIndexOf("x");
    			ch[index]=B[yu];
    			intNum/=10;
    			template=String.valueOf(ch);
    		}
    		int index= template.lastIndexOf("x");
    		System.out.println(template.substring(index+2));
    	}
    }
