莫尔斯英语

-2

所以程序的对象是在标题。我已经成功地将英语转换成莫尔斯电码，但相反的方式证明是困难的。我已经浏览了所有的论坛，并没有能够解决我的问题在这里。它似乎可以转换，它只是转换莫尔斯电码的最后一个字符。我也无法想出使用空格区分单词的方法。任何帮助将不胜感激。莫尔斯英语

的[转换摩尔斯电码，以英文文本与Java]可能的复制（http://stackoverflow.com/questions/29572916/converting-morse-code-to-english-text- with-java） –

如果你的当前输出与你想要的输出不匹配，并且你不知道为什么，那么是时候开始调试了。如果你不确定如何去做这件事，那么请看看：[如何调试小程序]（http://ericlippert.com/2014/03/05/how-to-debug-small-程式/）。它不会解决你的直接问题，但它会给你你可以遵循的步骤，应该可以帮助你自己解决它，或者即使这样做不成功，那么至少可以帮助你更好地隔离你的问题，以便你的问题可以更专注，更容易回答。 –

您只需创建一个地图，并添加所有键的莫尔斯电字符串和值的字母，然后遍历单词和从地图得到。有一些事情你必须处理，例如每个莫尔斯码应该由某些东西划定界限，然后单词应该是不同的。就像你目前有一个单词有3个空格，你将不得不划定间距的莫尔斯值，否则我没有看到一种方式来区分。

这里有一个例子：

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));  
    } 
}

修正我的代码！在main方法中不需要调用split（），只需要在convertToEnglish方法中分割即可。这里是我的修订方法：

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]); 
    } 
}
