用Java逐字符读取文本文件到2D数组中 [英] Reading a text file character by character into a 2D array in Java

问题描述

作为我的面向对象课程的一部分，我们将设计一个战舰游戏，该游戏使用TUI最终实现GUI。
根据设计，我们将从一个类似于b的文本文件中读取AI的飞船位置

As part of my Object Oriented class, we are to design a Battleship game which uses a TUI to eventually implement a GUI. According to the design, we are to read the AI's ship locations from a text file that will look similar to the one b

 ABCDEFGHIJ
1
2 BBBB
3
4       C
5D      C
6D
7AAAAA
8     SSS  
9
0

其中字母代表不同的船。我当前的游戏实现使用二维字符数组，因此我希望能够读取文本文件并创建相应的2D数组。我看到了一些内置函数，可让您读取下一个String或下一个Integer，但我只想逐个字符地读取它。有没有办法做到这一点？
提前谢谢！

Where the letters represent different ships. My current implementation of the game uses a 2 dimensional array of characters, so I would like to be able to read the text file and create the corresponding 2D array. I've seen a few built in functions that allow you to read the next String or the next Integer, but I just want to read it character by character. Is there a way to do this? Thanks in advance!

推荐答案

最简单的方法是先逐行读取文件，然后再读取行逐个字符。通过使用内置实用程序，可以避免处理新行的复杂性，因为它们会因OS / Editor而异。

The simplest way to do this, in my opinion, is to first read the file line-by-line then read those lines character-by-character. By using a built-in utility, you can avoid the complexities of handling new lines because they vary by OS/Editor.

BufferedReader文档

    BufferedReader fileInput = new BufferedReader(new FileReader("example.txt"));
    String s;
    while ((s = fileInput.readLine()) != null) {
        for (char c : s.toCharArray()) {
            //Read into array
        }
    }
    fileInput.close();
