Java - 按字符输入扫描？ [英] Java - input scanned character-by-character?

问题描述

我的朋友告诉我他需要编写一个代码，将莫尔斯代码翻译成英文，他真的很挣扎（他的老师向他们展示了该程序的界面，但实际上并没有给他们提供源代码，我发现真的很愚蠢，因为你不能真正制作一个程序，而没有引用一些界面元素，如按钮和复选框）。我虽然自己也尝试过，因为我喜欢挑战。



无论如何，我希望逐个字符地检查用户的输入，这意味着如果有人输入Hi，代码将不会检查Hi，而是分别检查h和i，然后显示两者的莫尔斯代码。 （大小写并不重要。现在，我只想把翻译下来）



我该怎么做？



我尝试了什么：



我还没有尝试过任何东西。

My friend just told me he needs to write a code that translates Morse code to English, and he's really struggling (his teacher showed them the interface for the program, but didn't actually give them the source code for it, which I find really stupid, since you can't really make a program, without making some reference to interface elements such as button and checkboxes). I though I'd try doing it myself, since I like a challenge.

Anyway, so I want the input of the user to be checked character-by-character, which means if someone puts in "Hi", the code won't check for "Hi", but instead for "h" and "i" separately, and then display the Morse code equivalent for both. (upper and lower case don't matter much. Right now, I just want to get the translation down)

How would I do this?

What I have tried:
