请写一个java程序，要求如下：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" }; 设置参数一个小于100的英文，将其翻成数字示。例如输入fifty one,输出51

好的，以下是一个简单的 Java 程序，可以将小于 100 的英文翻译成数字：

import java.util.Scanner;

public class EnglishToNumber {
    public static void main(String[] args) {
        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","forty","fifty", "sixty","seventy", "eighty","ninety" };
        
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入一个小于100的英文单词或数字：");
        String english = scanner.nextLine().trim().toLowerCase();
        
        int number = 0;
        if (english.matches("\\d+")) {
            // 如果输入的是数字，直接将其转成整数
            number = Integer.parseInt(english);
        } else {
            // 如果输入的是英文单词，按照题目要求进行翻译
            String[] words = english.split(" ");
            for (int i = 0; i < words.length; i++) {
                String word = words[i];
                int index = -1;
                if (i == 0) {
                    // 处理十位数
                    index = indexOf(z, word);
                    if (index >= 0) {
                        number += (index + 2) * 10;
                        continue;
                    }
                } else {
                    // 处理个位数
                    index = indexOf(x, word);
                    if (index >= 0) {
                        number += index;
                        continue;
                    }
                    index = indexOf(y, word);
                    if (index >= 0) {
                        number += index + 10;
                        continue;
                    }
                }
                System.out.println("无法识别的单词：" + word);
                return;
            }
        }
        
        System.out.println("翻译结果：" + number);
    }
    
    private static int indexOf(String[] array, String word) {
        for (int i = 0; i < array.length; i++) {
            if (array[i].equals(word)) {
                return i;
            }
        }
        return -1;
    }
}

可以按照提示输入一个小于 100 的英文单词或数字，程序会将其翻译成数字并输出。例如输入 fifty one，输出 51。注意，程序对于无法识别的单词会直接退出。
