Java.io.BufferedWriter.write() Method
Description
The java.io.BufferedWriter.write(char[] cbuf, int off, int len) methods writes a section of character buffer to the writer. Offset off from which to start reading characters and the len is the length of the section from the character buffer.
Declaration
Following is the declaration for java.io.BufferedWriter.write(char[] cbuf, int off, int len) method:
public void write(char[] cbuf, int off, int len)
Parameters
cbuf -- Character array to be written
off -- Offset off to start reading character buffer
len -- Number of characters to be written 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 public void write(char[] cbuf, int off, int len) method.
package com.tutorialspoint; import java.io.BufferedWriter; import java.io.IOException; import java.io.StringWriter; public class BufferedWriterDemo { public static void main(String[] args) throws IOException { StringWriter sw = null; BufferedWriter bw = null; char[] cbuf = "ABCDEFGHIJKLMN".toCharArray(); try{ // create string writer sw = new StringWriter(); //create buffered writer bw = new BufferedWriter(sw); // write from specified character buffer to stream bw.write(cbuf, 2, 5); // forces out the characters to string writer bw.flush(); // string buffer is created StringBuffer sb = sw.getBuffer(); //prints the string System.out.println(sb); }catch(IOException e){ // if I/O error occurs e.printStackTrace(); }finally{ // releases any system resources associated with the stream if(sw!=null) sw.close(); if(bw!=null) bw.close(); } } }
Let us compile and run the above program, this will produce the following result:
