为什么我的Java莫尔斯电码翻译器给出了错误的输出？

Question

import java.util.Scanner;
public static void main ( String [] args )
{

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

    String [] english =  { "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", " "};

    Scanner input = new Scanner ( System. in );
    System.out.println ( "Enter 1 to translate Morse Code to English or 2 to translate English to Morse Code:");
    int userChoice = input.nextInt();
    String translateMe;

    while (userChoice < 1 || userChoice > 2 ) // Ensures user enters a valid choice
    {
        System.out.println( "Not a valid entry. Enter 1 to translate Morse Code to English or 2 to translate English to Morse Code:");
        userChoice = input.nextInt();
    }

   if (userChoice == 1 )
    {
        System.out.println("Please enter a Morse Code statement to translate. Separate letters with spaces and words with a ' | '" );
        translateMe = input.next();

        String [] morseChar = translateMe.split(" ");

        for( int x = 0; x < morseChar.length; x++)
        {
            String letter = morseChar[ x ];
            for ( int index = 0; index < morse.length; index++ )
            {
                if(morse [ index ].equals(letter))
                {
                    System.out.print(english[ index ]); // Display character at matching index position of English array to show translation
                }
            }
        }

        }

    else
    {
        System.out.println("Please enter an English statement to translate:");
        translateMe = input.next();
        translateMe = translateMe.toLowerCase();

        String [] englishChar = translateMe.split("(?!^)");

        for ( int x = 0; x < englishChar.length; x++)
        {
            String letter = englishChar [ x ];

            for (int index = 0; index < english.length; index++)
            {
                if( english [index].equals( letter ))
                {
                    System.out.print(morse[index] + " "); // Display Morse Code array character at matching index position to show translation
                }

            }
        }

    }

}

及其对应的莫尔斯电码

作为测试用语。当我用这个短语把英语翻译成莫尔斯电码时，我得到了

Answer 1

由于使用扫描仪，从莫尔斯到英语的翻译不起作用。您需要使用nextLine()，如下所示：

if (userChoice == 1 )
{
    translateMe = input.nextLine();
    System.out.println("Please enter a Morse Code statement to translate. Separate letters with spaces and words with a ' | '" );
    translateMe = input.nextLine();

之后，它似乎可以很好地翻译，即使使用split命令也是如此。

产出：

[.-, -..., -.-.]
abc

Please enter a Morse Code statement to translate. Separate letters with spaces and words with a ' | '
- --- | -... .
[-, ---, |, -..., .]
