Java BufferedReader Example

If you want to read a file in java using BufferedReader, use below code as template and reuse it the way you like.

BufferedReader reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.

1) Use BufferedReader without try-with-resources (Before Java 7)

package com.howtodoinjava.examples.io;

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

public class BufferedReaderExample 
{
	public static void main(String[] args)
	{
		BufferedReader bufferedReader = null;

		try 
		{

			String currLine;

			bufferedReader = new BufferedReader(new FileReader("C:\\temp\\testOut.txt"));

			while ((currLine = bufferedReader.readLine()) != null)
			{
				System.out.println(currLine);
			}

		}
		catch (IOException e) 
		{
			e.printStackTrace();
		} 
		finally 
		{
			try 
			{
				if (bufferedReader != null)
					bufferedReader.close();
			} 
			catch (IOException ex) 
			{
				ex.printStackTrace();
			}
		}
	}
}

2) Use BufferedReader with try-with-resources (Java 7 Onwards)

package com.howtodoinjava.examples.io;

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

public class BufferedReaderExample 
{
	public static void main(String[] args)
	{
		try (BufferedReader bufferedReader = new BufferedReader(new FileReader("C:\\temp\\testOut.txt")))
		{
 
			String currLine;
 
			while ((currLine = bufferedReader.readLine()) != null) 
			{
				System.out.println(currLine);
			}
 
		} 
		catch (IOException e) 
		{
			e.printStackTrace();
		}
	}
}
