设有3个数组内容如下:String x[]={"zero","one","two","three",four","five","six",seven","eight","ni
设有3个数组内容如下:
String x[]={"zero","one","two","three",four","five","six",seven","eight","nine"} ;
String y[]={ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen" };
String z[]={"twenty","thirty","fourty","fifty","sixty","seventy","eighty","ninety" };
用Java命令行输入一个小于100的整数,将其翻成英文表示.
例如：
输入32,输出：thirty two
输入14,输出：fourteen
输入8,输出：eight
反之,输入英文表示,输出相应的整数.
public class test1 {
public static void main(String []args){
System.out.println(CtoE (32));
System.out.println(CtoE (14));
System.out.println(CtoE (8));
}
public static String CtoE(int a){
String x[]={"zero","one","two","three","four","five","six","seven","eight","nine"} ;
String y[]={"ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen" };
String z[]={"twenty","thirty","fourty","fifty","sixty","seventy","eighty","ninety" };
if(a>=0&a=10&a=20&a

public static void main(String[] args) {
System.out.println(CtoE("twenty two"));
System.out.println(CtoE("ten"));

这是最笨的方法了,其他的我还不知道,这个方法就是数越大,if越多,可以实现大于100的数,如果你常用的话,可以把这个写成一个通用的工具类
