莫爾斯英語

-2

所以程序的對象是在標題。我已經成功地將英語轉換成莫爾斯電碼，但相反的方式證明是困難的。我已經瀏覽了所有的論壇，並沒有能夠解決我的問題在這裏。它似乎可以轉換，它只是轉換莫爾斯電碼的最後一個字符。我也無法想出使用空格區分單詞的方法。任何幫助將不勝感激。莫爾斯英語

的[轉換摩爾斯電碼，以英文文本與Java]可能的複製（http://stackoverflow.com/questions/29572916/converting-morse-code-to-english-text- with-java） –

如果你的當前輸出與你想要的輸出不匹配，並且你不知道爲什麼，那麼是時候開始調試了。如果你不確定如何去做這件事，那麼請看看：[如何調試小程序]（http://ericlippert.com/2014/03/05/how-to-debug-small-程式/）。它不會解決你的直接問題，但它會給你你可以遵循的步驟，應該可以幫助你自己解決它，或者即使這樣做不成功，那麼至少可以幫助你更好地隔離你的問題，以便你的問題可以更專注，更容易回答。 –

您只需創建一個地圖，並添加所有鍵的莫爾斯電字符串和值的字母，然後遍歷單詞和從地圖得到。有一些事情你必須處理，例如每個莫爾斯碼應該由某些東西劃定界限，然後單詞應該是不同的。就像你目前有一個單詞有3個空格，你將不得不劃定間距的莫爾斯值，否則我沒有看到一種方式來區分。

這裏有一個例子：

public static void convertToEnglish(String[] multiMorseWords) { 


     Map<String, String> morse = new HashMap<String, String>(); 
     morse.put(".-", "a"); 
     morse.put("-...", "b"); 
     // etc.. add all the morse code inputs 

    for (String word : multiMorseWords) { 
     System.out.println(morse.get(word));  
    } 
}

修正我的代碼！在main方法中不需要調用split（），只需要在convertToEnglish方法中分割即可。這裏是我的修訂方法：

public static void convertToEnglish(String morseSentence) 
{ 
    int i, j; 

    String alphabet = ("abcdefghijklmnopqrstuvwxyz1234567890 "); 

    String [] morse = new String[] { ".-","-...","-.-.","-..",".","..-.","--.","....","..",".---","-.-",".-..","--", 
    "-.","---",".--.","--.-",".-.","...","-","..-","...-",".--","-..-","-.--","--..", 
    ".----","..---","...--","....-",".....","-....","--...","---..","----.","-----", "|" };  

    String [] morseChars = morseSentence.split(" "); 
    String selectedMorse; 
    char [] englishAns = new char[morseChars.length]; 

    for(i = 0; i < morseChars.length; i++) 
    { 
    selectedMorse = morseChars[i]; 

    for(j = 0; j < morse.length; j++) 
    { 
     if(selectedMorse.equals(morse[j])) 
     { 
     englishAns[i] = alphabet.charAt(j); 
     } 
    } 
    } 

    for(i = 0; i < englishAns.length; i++) 
    { 
    System.out.print(englishAns[i]); 
    } 
}
