Reading lines from file using BufferedReader

Question

Can I read lines of file between two concrete positions (not begin & and) using BufferedReader in Java? I know how to read all lines from file by this method, but I need to read only one fragment of file.

1) Does the file contain records of fixed size? If so, consider using a RandomAccessFile. 2) If not, you can read through the file and start saving the text when you reach your begin position, and then stop reading and close the file once you've passed your end position. — Hovercraft Full Of Eels

Can I write like this line = "SomeString" while (line = reader.readLine() != "endString") — user2842269

No -- never use == or != to compare Strings ever. Use equals(...) or equalsIgnoreCase(...) instead. — Hovercraft Full Of Eels

while (!(currentLine = reader.readLine()).equals(endLine))?? — user2842269

Yes you can

bufferedReader.skip(numberOfCharsToSkip);

See: http://docs.oracle.com/javase/7/docs/api/java/io/BufferedReader.html#skip%28long%29
