java忽略空行读文件,Java：如何通过忽略“ \n”来逐行读取文件

I'm trying to read a tab separated text file line per line. The lines are separated by using carriage return ("\r\n") and LineFeed (\"n") is allowed within in tab separated text fields.

Since I want to read the File Line per Line, I want my programm to ignore a standalone "\n".

Unfortunately, BufferedReader uses both possibilities to separate the lines. How can I modify my code, in order to ignore the standalone "\n"?

try

{

BufferedReader in = new BufferedReader(new FileReader(flatFile));

String line = null;

while ((line = in.readLine()) != null)

{

String cells[] = line.split("\t");

System.out.println(cells.length);

System.out.println(line);

}

in.close();

}

catch (IOException e)

{

e.printStackTrace();

}

解决方案

Use a java.util.Scanner.

Scanner scanner = new Scanner(new File(flatFile));

scanner.useDelimiter("\r\n");

while (scanner.hasNext()) {

String line = scanner.next();

String cells[] = line.split("\t");

System.out.println(cells.length);

System.out.println(line);

}
