为我的编程课创建一个摩尔斯电码翻译器，输出出现问题 [英] Creating a Morse Code translator for my programming class,having troubles with the output
问题描述
这是我在该平台上的第一篇文章，对Java编程来说还很新，而且英语也不太好:p
我的老师要求一个莫尔斯电码翻译器，它能对字母进行莫尔斯电击，反之亦然.
这是我想出的代码:
import java.util.Scanner;
public class Morse2 {
public static void main(String[] args){
String[] letras = { "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"};
String[] MORSE = {
".-" ,"-...","-.-.","-.." ,"." ,
"..-.","--." ,"....",".." ,".---",
"-.-" ,".-..","--" ,"-." ,"---" ,
".--.","--.-",".-." ,"..." ,"-" ,
"..-" ,"...-",".--", "-..-","-.--",
"--.."};
System.out.println("Insira uma frase em codigo morse para uma traducao para texto ou vice-versa");
Scanner in=new Scanner(System.in);
String frase =in.nextLine();
String resp="";
frase=frase.toLowerCase();
String[] paraletras=frase.split("");
String[]paraMorse=frase.split(" ");
for(int i=0;i< paraletras.length;i++){
for(int j=0;j< letras.length ;j++){
if (paraletras[i].equals(letras[j])){
resp=resp+ MORSE[j]+" ";}
}
}
for(int k=0;k<paraMorse.length;k++){
for (int l=0;l<MORSE.length;l++){
if(paraMorse[k].equals(MORSE[l])){
resp=resp+letras[l]+ " ";}}
}
System.out.print(resp);}
}
该类编译良好，但是我的输出出现了一些问题，更具体地说是输出的顺序:
例如我的输入"a b -.- c" 我想要的是".- -... k -.-". 我得到的是".- -... -.-.k" 我相信这是因为我使用2代替了1周期，但我真的无法告诉该怎么做. 同样，当用户写一个不可能的字符(如"*")时，我认为该字符可能会加上?"在那个位置上，即时通讯也在苦苦挣扎，我不知道是否应该使用if循环或其他方式
请帮助我，谢谢大家^^
很抱歉成为这样的菜鸟，但可能也是因为ive从8个小时前就已经在这里了，但是为什么这段代码只给我这封信的莫尔斯电码"a"几次?
import java.util.Scanner;
public class Morse2 {
public static void main(String[] args){
String[] abecedario = { "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"};
String[] MORSE = {
".-" ,"-...","-.-.","-.." ,"." ,
"..-.","--." ,"....",".." ,".---",
"-.-" ,".-..","--" ,"-." ,"---" ,
".--.","--.-",".-." ,"..." ,"-" ,
"..-" ,"...-",".--", "-..-","-.--",
"--.."};
System.out.println("Insira uma frase em codigo morse para uma traducao para texto ou vice-versa");
Scanner in=new Scanner(System.in);
String frase =in.nextLine();
String resp="";
frase=frase.toLowerCase();
String[] palavra=frase.split(" ");
for(int i=0;i< palavra.length;i++){
String letra=palavra[i];
String novochar="";
for (int j=0;j<abecedario.length;j++){
if (abecedario[j].equals(letra));
novochar=MORSE[j];
break;
}
if(novochar==""){
for (int j=0;j<MORSE.length;j++){
if (MORSE[j].equals(letra));
novochar=abecedario[j];
break;
}
}
if(novochar==""){
novochar="?";
continue;
}
resp=resp+novochar+" ";
}
System.out.println(resp);
}
}
this is my first post on this platform ,im kinda new to this java programing and also not that good at english :p
My teacher asked for a morse code translator that does morse to letters and vice versa
Here's the code i came up with:
import java.util.Scanner;
public class Morse2 {
public static void main(String[] args){
String[] letras = { "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"};
String[] MORSE = {
".-" ,"-...","-.-.","-.." ,"." ,
"..-.","--." ,"....",".." ,".---",
"-.-" ,".-..","--" ,"-." ,"---" ,
".--.","--.-",".-." ,"..." ,"-" ,
"..-" ,"...-",".--", "-..-","-.--",
"--.."};
System.out.println("Insira uma frase em codigo morse para uma traducao para texto ou vice-versa");
Scanner in=new Scanner(System.in);
String frase =in.nextLine();
String resp="";
frase=frase.toLowerCase();
String[] paraletras=frase.split("");
String[]paraMorse=frase.split(" ");
for(int i=0;i< paraletras.length;i++){
for(int j=0;j< letras.length ;j++){
if (paraletras[i].equals(letras[j])){
resp=resp+ MORSE[j]+" ";}
}
}
for(int k=0;k<paraMorse.length;k++){
for (int l=0;l<MORSE.length;l++){
if(paraMorse[k].equals(MORSE[l])){
resp=resp+letras[l]+ " ";}}
}
System.out.print(resp);}
}
The class compiles fine but im having some issues with my output,more specifically the order of the output:
e.g My input " a b -.- c " What i wanted ".- -... k -.-." What i got ".- -... -.-. k" I believe that's because i used 2 for cycles instead of 1 but i cant really tell how to do it.Would apreciate some help Also when the user writes an impossible character like "*" im suppossed to put an "?" in that position and im also strugling on that i dont know if i should use a if else cycle or what
Please help me and thank you everybody ^^
Sorry to be such a noob,but probably is also because ive been here since 8 hours ago but why is this code giving me only the morse code to the letter 'a' a couple times?
import java.util.Scanner;
public class Morse2 {
public static void main(String[] args){
String[] abecedario = { "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"};
String[] MORSE = {
".-" ,"-...","-.-.","-.." ,"." ,
"..-.","--." ,"....",".." ,".---",
"-.-" ,".-..","--" ,"-." ,"---" ,
".--.","--.-",".-." ,"..." ,"-" ,
"..-" ,"...-",".--", "-..-","-.--",
"--.."};
System.out.println("Insira uma frase em codigo morse para uma traducao para texto ou vice-versa");
Scanner in=new Scanner(System.in);
String frase =in.nextLine();
String resp="";
frase=frase.toLowerCase();
String[] palavra=frase.split(" ");
for(int i=0;i< palavra.length;i++){
String letra=palavra[i];
String novochar="";
for (int j=0;j<abecedario.length;j++){
if (abecedario[j].equals(letra));
novochar=MORSE[j];
break;
}
if(novochar==""){
for (int j=0;j<MORSE.length;j++){
if (MORSE[j].equals(letra));
novochar=abecedario[j];
break;
}
}
if(novochar==""){
novochar="?";
continue;
}
resp=resp+novochar+" ";
}
System.out.println(resp);
}
}
