我正在尝试将英文字母转换为莫尔斯电码，但是当涉及多个输入字母时，我遇到了困难。我可以说出我的问题是什么，但不能解决。
我对Java还是很陌生，我知道我的做法很草率和重复，但这是我到目前为止所能掌握的全部方法。
我做了一些场景，例如，找出输入中有多少个字母，然后转换每个字母；但同样，我不确定这是否可行或什至可行。

morseA = "•-";

}
System.out.println(morseTranslation.charAt(0) + " " + morseTranslation.charAt(1));
}
}
}
// if statements
// long but might work
// charAt find out how many letters they typed in/inputed
// make something that uses chatAt for each character depending on how many there are,
// and individually translate each letter
最佳答案
请尝试使用此编辑后的代码，它将以莫尔斯电码打印输入的单词
