java - JAVA翻译程序

Question

所以，我和我的 friend 用 JAVA 编写了一个英语到 Al Bhed(FFX 的方言)代码。我想实现“括号(或 [])内的字符未翻译”的功能，但我不知道如何实现。有人可以帮我实现它吗？这是代码。它不是完整的数组格式，因为我不太熟悉数组。

import java.io.*;

class albhed
    {
    public static void main (String[] args) throws IOException
        {
            BufferedReader dataIn = new BufferedReader (new InputStreamReader (System.in));

            int a;
            String b;

            System.out.println("English to Al Bhed, input 1.");
            System.out.println("Al Bhed to English, input 2.");
            b = dataIn.readLine();
            a = Integer.parseInt(b);
            if (a == 1)
                {
                    System.out.println("Enter English characters to translate.");
                    String x = dataIn.readLine();
                    int y = x.length();
                    String z[] = x.split("");
                    System.out.println("The translated characters from English to Al Bhed:");
                    for(int i = 0; i < y; i++)
                        {

好吧，您可以使用 boolean 值来存储这样的事实:您不想每次遇到 [ 时都翻译任何字符，直到找到任何 ]

                boolean must_translate = true;
                for(int i = 0; i < y; i++)
                    {
                        if (z[i].equals("[")) { must_translate = false; }
                        else if (z[i].equals("]")) { must_translate = true; }
                        else {
                           if (must_translate) {
                               switch (z[i])
                               // (....)
                           } else {
                               System.out.print(z[i]);
                           }
                        }

当然，您的代码远非最佳，但这不是重点。

(仅供引用:您不必将字符串拆分为较小的字符串。最好直接访问字符串的 soem 索引处的字符。此外，最好构建一个 StringBuffer 对象，并在末尾打印它，而不是为每个字符调用 System.out.print。而且您的 switch 部分很长。最好将翻译规则存储在数组或映射中。)
