英语 - 莫尔斯翻译器

Question

从莫尔斯翻译成英文就像是一种魅力，但是将短语或句子（用空格分隔的多个单词）从英语翻译成莫尔斯只会产生翻译成莫尔斯的第一个单词。例如，如果我输入'Hello World'，翻译人员只会返回

'.... .- .. .- .. ---'。

为了从翻译者处获得完整的句子，我需要改变什么？我已经指出我认为问题在哪里，并且注意翻译者忽略标点符号。 TIA

我相信，基于http://www.tutorialspoint.com/java/util/scanner_next.htm（java.util.Scanner.next的定义），您String englishInput = scan.next();线在本节：

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(); 
} 

只读取第一个记号，这是第一个单词，因为单个空格是空白的，而不是nextLine（），它正确接受了整个句子。
