如何处理Java中不可见的换行符？

Question

I am currently working on the code for a game in Java. I am supposed to fill an array with characters from a .txt file. The problem is that my programm also stores the invisible new line characters from the file and as a result the array is not filled correctly. I have already tried to replace the invisible characters but the result was disastrous (my array would only be filled for the first line and the rest would remain empty) here is my block of code used for the array:

    import java.util.*;
    import java.io.*;

    public class Test {
        public static void main(String[] args) throws IOException{
        char background[][] = new char [14][20];

    try {

        FileInputStream fileinput = new FileInputStream("background.txt");
            int r;
            for(int i=0;i<14;i++){
                for(int j=0;j<20;j++){//<<THIS LINE WAS CHANGED
                    while((r = fileinput.read()) != -1){
                        char c = (char) r;
                        background[i][j] = c;
                        break;
                    }
                }
            }
            fileinput.close();
        }

        catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        for (int i=0;i<14;i++){
            for(int j=0;j<20;j++){
                System.out.print(background[i][j]);
            }
        }
}




}

Answer 1

以字符串形式读取该行，在该行上调用.trim（）方法，然后使用.toCharArray（）将其拆分为char。

Answer 2

如果您在Windows上运行，请使用“ \\ r \\ n”检查新行或从系统属性中获取特定于平台的行

String lineSeparator = System.getProperty("line.separator");
