Example

The following example shows the usage of java.io.BufferedWriter.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:
