Proper way to read file line by line?


In java, what's the proper method to read a file, line by line? In my case, the data is human readable characters. It seems there are many different ways on the net. I guess I just want one large string representing the contents of the file.

.readline() from BufferedReader.

BufferedReader reader = new BufferedReader(file);
for (String line = reader.readLine(); line != null; line = reader.readLine()) {
   // process line

BufferedReader in  = new BufferedReader(new FileReader("somefile")); would be good.
