Java reads files by row

In the past, I used Java to read a lot of data and process strings. I read files by row many times. Later I used the Perl class library and I didn't write it myself, for a long time, you don't have to forget how to use Java to read files by row. For future convenience, remember here. It mainly uses bufferedreader to read data.
SimpleCodeAs follows:
 

Filereader reader = new filereader ("C: test.txt"); // The parameter here is the file path, which can read all common types of files bufferedreader BR = new bufferedreader (Reader ); string STR = NULL; while (STR = BR. readline ())! = NULL) {// Response Processing...} // closes the read/write stream Br. Close (); reader. Close ();
