Example:

// Java program to demonstrate the example 
// of String toString() method of CharArrayWriter

import java.io.*;

public class ToStringOfCAW {
 public static void main(String[] args) {
  CharArrayWriter caw = null;
  char[] c = {
   'j',
   'a',
   'v',
   'a'
  };

  try {
   // Instantiates CharArrayWriter
   caw = new CharArrayWriter();

   // By using write() method is to
   // write the character array (c)
   // to the stream caw
   caw.write(c);

   // By using toString() method is 
   // to represent the caw as a string
   System.out.print("caw.toString(): " + caw.toString());
   System.out.println();
  } catch (Exception ex) {
   System.out.println(ex.toString());

  } finally {
   // Free all resources linked with this
   // stream
   if (caw != null)
    caw.close();
  }
 }
