在Java中调用多维数组的更好方法是什么？

我是全新的Java，从我的导师那里得到了一个编码项目。我正在创建一个Java程序，如果某人去另一个国家旅行，它将帮助他们。现在我一直在努力寻找一种更好的方法，将一个短语从英语翻译成我创建的多维数组中列出的一种语言。很抱歉，这篇文章太长了。这是我几个月来第二次使用堆栈溢出

String[][] Phrases = 
{{"Hola", "Adios", "Gracias", "Si", "No", "Lo siento or perdón"},//Spanish
{"Bonjour", "Goodbye", "Au revoir", "Oui", "Non", "Je suis désolé"},//French
{"Merhaba", "Güle güle", "teşekkür ederim", "Evet", "yok hayır", "üzgünüm"},//Turkish
{"Здравствуйте (Zdravstvuyte)", "Прощай (Proshchay)", "Спасибо (Spasibo)", "да (da)", "нет (net)", "прости (prosti)"}};//Russian

我有一个switch语句，在案例4中，我将使用if语句调用数组，根据用户的输入翻译英语短语。把它翻译成西班牙语很好，但是如果我要为其他三种语言做的话，那就有很多事情要做

switch (option){




    case 4: System.out.println("Select which phrase 1 through 6 you would like to translate to.");
        System.out.println("1 - Hello, \n2 - Goodbye, \n3 - Thank you, \n4 - Yes, \n5 - No, \n6 - I'm Sorry");
        int speak = 0;
        speak = info.nextInt();

         if (speak ==1){
        System.out.println("Option " + speak + " translates to " + Phrases[0][0]);
    } else if (speak == 2){
        System.out.println("Option " + speak + " translates to " + Phrases[0][1]);
    }else if (speak == 3){
        System.out.println("Option " + speak + " translates to " + Phrases[0][2]);
    }else if (speak == 4){
        System.out.println("Option " + speak + " translates to " + Phrases[0][3]);
    }else if (speak == 5){
        System.out.println("Option " + speak + " translates to " + Phrases[0][4]);
    }


           break;

    //Give user menu of phrases, store phrase input, call array for phrase,
}

肯定有比写一堆if语句更好的方法。调用数组来翻译用户想要翻译的短语的更好方法是什么？我很抱歉，如果这没有任何意义，但在这一点上，我完全迷失了方向。下面是我到目前为止得到的一切。我用的是蓝色J，我有两门课。我想做的就是找到一种更简单的方法，当用户选择要翻译的短语时，将英语短语翻译成所提供的四种语言之一

您的speak整数比该单词的索引多出一个，因此请使用speak-1访问该单词：

case 4: System.out.println("Select which phrase 1 through 6 you would like to translate to.");
        System.out.println("1 - Hello, \n2 - Goodbye, \n3 - Thank you, \n4 - Yes, \n5 - No, \n6 - I'm Sorry");
        int speak = 0;
        speak = info.nextInt();
        System.out.println("Option " + speak + " translates to " + Phrases[0][speak-1]

---

如果使用此方法，最好使用额外的If语句检查speak是否也在1到5之间。

您已经有了要返回的翻译索引。您根本不需要

if

语句

替换：

         if (speak ==1){
    System.out.println("Option " + speak + " translates to " + Phrases[0][0]);
} else if (speak == 2){
    System.out.println("Option " + speak + " translates to " + Phrases[0][1]);
}else if (speak == 3){
    System.out.println("Option " + speak + " translates to " + Phrases[0][2]);
}else if (speak == 4){
    System.out.println("Option " + speak + " translates to " + Phrases[0][3]);
}else if (speak == 5){
    System.out.println("Option " + speak + " translates to " + Phrases[0][4]);
}

与：

if（说话>0&&speak<5）{
System.out.println（“选项”+speak+”翻译为“+Phrases[0][speak-1]）；
}否则{
//按照您的意愿处理无效输入
}

感谢所有帮助并发布解决方案的人。我从两位发布答案的人那里看到了答案，解决方案奏效了，但只有在翻译成西班牙语时才起作用。我需要它能够根据用户所在的四个位置中的哪一个来翻译短语。所以我添加了一些if语句，得到了这个

 if(spot == 1 && speak > 0 && speak < 7){
      System.out.println("Option " + speak + " translates to " + Phrases[0][speak-1]);
     }else if ((spot == 2 && speak > 0 && speak < 7)) {         
         System.out.println("Option " + speak + " translates to " + Phrases[1][speak-1]);
         //handle the invalid input however you want
      } else if ((spot == 3 && speak > 0 && speak < 7)) {         
         System.out.println("Option " + speak + " translates to " + Phrases[2][speak-1]);

        }else if ((spot == 4 && speak > 0 && speak < 7)) {         
         System.out.println("Option " + speak + " translates to " + Phrases[3][speak-1]);
        }

if（spot==1&&speak>0&&speak<7）{
System.out.println（“选项”+speak+”翻译为“+Phrases[0][speak-1]）；
}如果（（spot==2&&speak>0&&speak<7））{
System.out.println（“选项”+speak+”翻译为“+Phrases[1][speak-1]）；
//按照您的意愿处理无效输入
}如果（（spot==3&&speak>0&&speak<7））{
System.out.println（“选项”+speak+”翻译为“+Phrases[2][speak-1]）；
}如果（（spot==4&&speak>0&&speak<7））{
System.out.println（“选项”+speak+”翻译为“+Phrases[3][speak-1]）；
}

我刚刚在if语句中添加了

spot

，这样它就可以知道用户选择了哪个国家，并将其翻译成特定的语言。然后我让

说<7

，因为它没有翻译选项5和6中的短语。这还是个新概念，但当我告诉你我发现它时有多兴奋时，我非常高兴。

地图是用于此目的的，但是因为你还没有学会它们，你的教授很可能让你这么做。我尝试了下面给我的两种解决方案，它们都起了作用，但只有在将短语翻译成西班牙语时才起作用。如果用户选择了其他三个国家中的一个，如何将其翻译成其他语言？

 if(spot == 1 && speak > 0 && speak < 7){
      System.out.println("Option " + speak + " translates to " + Phrases[0][speak-1]);
     }else if ((spot == 2 && speak > 0 && speak < 7)) {         
         System.out.println("Option " + speak + " translates to " + Phrases[1][speak-1]);
         //handle the invalid input however you want
      } else if ((spot == 3 && speak > 0 && speak < 7)) {         
         System.out.println("Option " + speak + " translates to " + Phrases[2][speak-1]);

        }else if ((spot == 4 && speak > 0 && speak < 7)) {         
         System.out.println("Option " + speak + " translates to " + Phrases[3][speak-1]);
        }
