Java BufferedOutputStream write(int b) method example

public void write(int b)
throws IOException

This method returns void.

Requires Java 1.0 and up

Below is a java code demonstrates the use of write(int b) method of BufferedOutputStream class. The example presented might be simple however it shows the behaviour of the write(int b) method.

package com.javatutorialhq.java.examples;

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Scanner;

/*
 * This example source code demonstrates the use of  
 * write() method of BufferedOutputStream class

public class BufferedOutputStreamWriteExample {

    public static void main(String[] args) {	
        
        
        try {
            // initialize File object
            File f = new File("C:javatutorialhqoutputtest_out.txt");
            
            // instantiate a new FileOutputStream
            FileOutputStream fos = new FileOutputStream(f);
            
            // using the above FileOutputStream
            // instantiate a BufferedOutputStream object
            BufferedOutputStream buffOut = new BufferedOutputStream(fos);
            
            // initialize variables
            String writeString = "This is a test string";
            
            // convert above String to character array
            char[] value = writeString.toCharArray();
            
            // write the values of the character array
            for(char c:value){
                buffOut.write((int)c);
            }
            // close the BufferedOutputStream
            buffOut.flush();
            buffOut.close();
            
            // read the output file
            System.out.println("*****Contents of output file*****");
            Scanner s = new Scanner(f);
            while(s.hasNextLine()){
                System.out.println(s.nextLine());
            }
            s.close();
            
        } catch (FileNotFoundException e) {
            System.out.println("File path not found");
        } catch (IOException e) {
            System.out.println("IOException occured");
        }		

    }

}
