英語 - 莫爾斯翻譯器

Question

從莫爾斯翻譯成英文就像是一種魅力，但是將短語或句子（用空格分隔的多個單詞）從英語翻譯成莫爾斯只會產生翻譯成莫爾斯的第一個單詞。例如，如果我輸入'Hello World'，翻譯人員只會返回

'.... .- .. .- .. ---'。

爲了從翻譯者處獲得完整的句子，我需要改變什麼？我已經指出我認爲問題在哪裏，並且注意翻譯者忽略標點符號。 TIA

我相信，基於http://www.tutorialspoint.com/java/util/scanner_next.htm（java.util.Scanner.next的定義），您String englishInput = scan.next();線在本節：

if(answer.equals("E")) 
{ 
    Scanner scan2 = new Scanner(System.in); 
    System.out.print("Enter a word or phrase in English: "); 
    String englishInput = scan.next(); 
    System.out.println(toMorse(englishInput)); 
    scan2.close(); 
} 

只讀取第一個記號，這是第一個單詞，因爲單個空格是空白的，而不是nextLine（），它正確接受了整個句子。
