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();
}
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);
}
