Java.io.BufferedOutputStream.Write() Method
Description
The java.io.BufferedInputStream.Write(byte[], int, int) method writes to the stream starting at offset off of len bytes from the specified byte array b. For the length as large as this stream's buffer will flush the buffer and write the bytes directly to the output stream.
Declaration
Following is the declaration for java.io.BufferedOutputStream.write(byte[] b, int off, int len) method.
public void write(byte[] b, int off, int len)
Parameters
b − byte array as source data
off − The start offset in the source
len − number of bytes to write to the stream
Return Value
This method does not return any value.
Exception
IOException − If an I/O error occurs.
Example
The following example shows the usage of java.io.BufferedOutputStream.write(byte[] b, int off, int len) method.
package com.tutorialspoint; import java.io.BufferedOutputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; public class BufferedOutputStreamDemo { public static void main(String[] args) throws Exception { BufferedOutputStream bos = null; try { // create new output streams. baos = new ByteArrayOutputStream(); bos = new BufferedOutputStream(baos); // assign values to the byte array byte[] bytes = {1, 2, 3, 4, 5}; // write byte array to the output stream bos.write(bytes, 0, 5); // flush the bytes to be written out to baos bos.flush(); for (byte b:baos.toByteArray()) { // prints byte System.out.print(b); } } catch(IOException e) { // if any IOError occurs e.printStackTrace(); } finally { // releases any system resources associated with the stream if(baos!=null) baos.close(); if(bos!=null) bos.close(); } } }
Let us compile and run the above program, this will produce the following result −
