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命令行输入或在Eclipse中设置参数一个小于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。

好的，我来为您解答这个问题。

如果要将小于100的整数翻译成英文表示，可以按照以下步骤进行操作：

1. 首先，读取用户输入的整数，并将其保存在一个整型变量中。

2. 然后，对于小于20的数字，直接使用数组y中对应的英文单词输出即可。

3. 对于大于等于20的数字，可以将其分解为十位和个位两个数字，然后分别取对应的英文单词输出。

4. 这里需要注意的是，如果个位数字为0，则不需要输出，例如：20应该输出为twenty而不是twenty zero。

下面是一个完整的Java代码示例：

import java.util.Scanner;

public class NumberTranslator {
    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的整数：");
        int num = scanner.nextInt();

        if (num < 10) {
            System.out.println(x[num]);
        } else if (num < 20) {
            System.out.println(y[num - 10]);
        } else if (num < 100) {
            int ten = num / 10;
            int one = num % 10;
            if (one == 0) {
                System.out.println(z[ten - 2]);
            } else {
                System.out.println(z[ten - 2] + " " + x[one]);
            }
        } else {
            System.out.println("输入的数字不合法！");
        }
    }
}

如果要将英文表示的数字翻译成相应的整数，可以按照以下步骤进行操作：

1. 首先，读取用户输入的英文单词，并将其保存在一个字符串变量中。

2. 然后，遍历数组x、y和z，查找对应的英文单词，并记录下对应的数字。

3. 最后，将记录的数字组合起来，即可得到相应的整数。

下面是一个完整的Java代码示例：

import java.util.Scanner;

public class NumberTranslator {
    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的英文数字：");
        String str = scanner.nextLine();

        int num = 0;
        if (str.equals("zero")) {
            num = 0;
        } else if (str.length() <= 2) {
            for (int i = 0; i < y.length; i++) {
                if (str.equals(y[i])) {
                    num = i + 10;
                    break;
                }
            }
            if (num == 0) {
                for (int i = 0; i < z.length; i++) {
                    if (str.equals(z[i])) {
                        num = (i + 2) * 10;
                        break;
                    }
                }
                if (num == 0) {
                    for (int i = 0; i < x.length; i++) {
                        if (str.equals(x[i])) {
                            num = i;
                            break;
                        }
                    }
                }
            }
        } else {
            System.out.println("输入的单词不合法！");
            return;
        }
        System.out.println(num);
    }
}
