[英]Unable to translate morse to english
我有一個學校項目,我需要將莫爾斯語翻譯成英語。 我是 Java 的新手,所以我想知道您是否可以幫助我。 問題是我不確定我應該在while循環中放置什么以將莫爾斯電碼轉換為英文。 任何幫助,將不勝感激。 謝謝^^
public static void main(String[]args){
HashMap<Character,String> translations=new HashMap<Character,String>();
translations.put('A', ".-");
translations.put('B', "-...");
translations.put('C', "-.-.");
translations.put('D', "-..");
translations.put('E', ".");
translations.put('F', "..-.");
translations.put('G', "--.");
translations.put('H', "....");
translations.put('I', "..");
translations.put('J', ".---");
translations.put('K', "-.-");
translations.put('L', ".-..");
translations.put('M', "--");
translations.put('N', "-.");
translations.put('O', "---");
translations.put('P', ".--.");
translations.put('Q', "--.-");
translations.put('R', ".-.");
translations.put('S', "...");
translations.put('T', "-");
translations.put('U', "..-");
translations.put('V', "...-");
translations.put('W', ".--");
translations.put('X', "-..-");
translations.put('Y', "-.--");
translations.put('Z', "--..");
translations.put('0', "-----");
translations.put('1', ".----");
translations.put('2', "..---");
translations.put('3', "...--");
translations.put('4', "....-");
translations.put('5', ".....");
translations.put('6', "-....");
translations.put('7', "--...");
translations.put('8', "---..");
translations.put('9', "----.");
translations.put(' ', " ");
HashMap<String, Character> reversedHashMap = new HashMap<String, Character>();
for (char key : translations.keySet()){
reversedHashMap.put(translations.get(key), key);
}Scanner scan=new Scanner(System.in);
System.out.println("Welcome to the translator. Type 1 for English to Morse or type 2 for Morse to English: ");
int choice=scan.nextInt();
if(choice==1)
engToMorse(translations);
else if(choice==2)
morseToEng(reversedHashMap);
else{
System.out.println("Invalid Input!");
}
}
public static void engToMorse(HashMap<Character,String> translations){
Scanner scan=new Scanner(System.in);
System.out.println("Please enter the sentence that you want to translate to Morse here: ");
String sentence=scan.nextLine().toUpperCase();
int i=0;
while(i<sentence.length()){
System.out.printf(translations.get(sentence.charAt(i)));
i++;
}
}
public static void morseToEng(HashMap<String,Character> reversedHashMap){
Scanner scan=new Scanner(System.in);
System.out.println("Please enter the morse code that you want to translate to english: ");
String morse=scan.nextLine().toUpperCase();
int i=0;
while(i<morse.length()){
System.out.print();
i++;
}
}
讀取輸入后,按空格分割輸入字符串。 對於每個元素,查找字符(值)map 的摩爾斯電碼(鍵)並打印值。
for (String singleCode : morse.split(" ")) {
System.out.print(reversedHashMap.get(singleCode));
}
樣品輸入 output
Welcome to the translator. Type 1 for English to Morse or type 2 for Morse to English:
2
Please enter the morse code that you want to translate to english:
... -- ...

您可以簡單地逐個獲取莫爾斯電碼,在每一行中獲取一個莫爾斯電碼,對其進行處理並將其連接為結果字符串,如果您想在一行中獲取多個莫爾斯電碼,請在它們之間使用分隔符,然后根據拆分字符串該拆分器例如a #。
所以你會得到 --#.--#..-- 然后將其拆分為:
for (String singleMorse : morse.split("#")) {
System.out.print(reversedHashMap.get(singleCode));
}
注意:因為你的摩爾斯電碼中有SPACE ,所以使用SPACE以外的拆分器更簡單
