Program: How to convert byte array to reader or BufferedReader?


Sometimes we need to convert byte array object to reader object. Below example shows how to convert byte array to bufferedreader object.


package com.java2novice.files;

import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class MyByteArrayToReader {

	public static void main(String a[]){
		
		String str = "converting to input stream"+
						"\n and this is second line";
		byte[] content = str.getBytes();
		InputStream is = null;
		BufferedReader bfReader = null;
		try {
			is = new ByteArrayInputStream(content);
			bfReader = new BufferedReader(new InputStreamReader(is));
			String temp = null;
			while((temp = bfReader.readLine()) != null){
				System.out.println(temp);
			}
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			try{
				if(is != null) is.close();
			} catch (Exception ex){
				
			}
		}
		
	}
}

Output:
converting to input stream
 and this is second line

Transient and Volatile Modifiers
Transient: The transient modifier applies to variables only and it is not stored as part of its object's Persistent state. Transient variables are not serialized.

Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.
