小白求教，这道题怎么解啊

[不羡仙丶]

我的困惑在于怎么把拆分开的每个数字的拼音找到，并拼接在一起呢？

纯小白，才刚开始学，拜托大佬们指点下迷津

用枚举类：

package cddn;

import java.util.Scanner;

public class TestNumchn {
	public static void main(String[] args) {
		System.out.println("请输入一个数字：");
		Scanner sc = new Scanner(System.in);

		String input = sc.next();
		StringBuffer sb = new StringBuffer();
		int j = 1;
		if(Integer.parseInt(input) < 0){
			sb.append("fu ");
			j = 2;
		}
		String[] c = input.split("");
		for(;j < c.length;j++){
			sb.append(NUMCHN.getValue(Integer.parseInt(c[j])));
			sb.append(" ");
		}
		System.out.println(sb);
		sc.close();
	}
}
enum NUMCHN{
	YI(1,"yi"),
	ER(2,"er"),
	SAN(3,"san"),
	SI(4,"si"),
	WU(5,"wu"),
	LIU(6,"liu"),
	QI(7,"qi"),
	BA(8,"ba"),
	JIU(9,"jiu"),
	LING(0,"ling");
	private final int num;
	private final String chn;
	
	private NUMCHN(int num,String chn){
		this.num = num;
		this.chn = chn;
	}

	public int getNum() {
		return num;
	}

	public String getChn() {
		return chn;
	}
	
	public static String getValue(int num){
		for(NUMCHN numchn : NUMCHN.values()){
			if(num == numchn.getNum()){
				return numchn.getChn();
			}
		}
		return "";
	}
	
	
}

0-9 分别映射一个拼音 用switch 数字 就可以了

package com.huaxinhui.test;

import java.util.Scanner;

public class Tets02 {

public static void main(String[] args) {
Scanner scanneer = new Scanner(System.in);
int input=scanneer.nextInt();
String temp=input+"";
String output="";
for (int i = 0; i < temp.length(); i++) {
switch (temp.charAt(i)) {
case '-':
output=output+fu+" ";

case '1':

System.out.println(output.substring(0, output.lastIndexOf(" ")));
