How to read a file in java with example program
We can read java file using buffered reader class in java
We need to import java.io.BufferedReader in order to read java text file.
Create object of java.io.BufferedReader class by passing new FileReader("C:\\Sample.txt") object to the constructor.
In order to read line by line call readLine() method of BufferedReader class which returns current line. Initially first line of java text file
Program #1: Write a java program to read a file line by line using BufferedReader class
package com.instanceofjava.javareadfile;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class ReadFileBufferedReader {
/**

* @category: How to read java read file line by line using buffered reader
*/
public static void main(String[] args) {
BufferedReader breader = null;
try {
String CurrentLine;
breader = new BufferedReader(new FileReader("E://Sample.txt"));
while ((CurrentLine = breader.readLine()) != null) {
System.out.println(CurrentLine);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (breader != null)
breader.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
}
Output:
