Program: How to read a file using BufferedInputStream?

package com.java2novice.files;

import java.io.BufferedInputStream;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

public class MyFileReadBybis {

	public static void main(String a[]){
		
		InputStream is = null;
		BufferedInputStream bis = null;
		DataInputStream dis = null;
		try {
			is = new FileInputStream("/Users/ngootooru/sample.txt");
			bis = new BufferedInputStream(is);
			dis = new DataInputStream(bis);
			String temp = null;
			while((temp = dis.readLine()) != null){
				System.out.println(temp);
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

This is a test file, here we are
trying to read a file using BufferedReader.
We are trying to convert input stream object 
to reader object.
