How to read a file in Java

In Java, you can use the BufferedReader class as follows in order to read a file:

package demo;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

public class MyTextFileReader {

public static void main(String args[]){
try {
BufferedReader br = new BufferedReader(new FileReader(new File("F:/test.txt")));
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch ( IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
