Question

I have this function to read text file with BufferedReader. I want to know if I can called another function and pass the readline/continue to read text file. If it can pass, can it loop the same function?

Answer 1

A BufferedReader object is self-contained (thanks to Java’s heavy emphasis on Object Orientation), so you are free to pass it between functions and inside loops, and it will retain it’s state – including the read line.

However, if you are trying to call a method to process the line you have just read, then it would be much more efficient to pass the line itself to the method as a String, instead of passing the entire BufferedReader object.

while( myBufferedReader.ready() ) {
    String line = myBufferedReader.readLine();
    processLine( line );
}
