CharArrayWriter Class reset() method

• reset() method is available in java.io package.
• reset() method is used to reset this stream (CharArrayWriter) and it can re-use further without throwing away.
• reset() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• reset() method does not throw an exception at the time of resetting the stream.

Syntax:

    public void reset();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void reset() method of CharArrayWriter

import java.io.*;

public class ResetOfCAW {
 public static void main(String[] args) {
  CharSequence cs = "Java World!!!";
  CharArrayWriter caw = null;

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

   // By using append() method is to
   // append cs to the caw before calling
   // reset()
   caw.append(cs);

   // By using toString() method is 
   // to represent the caw as a string
   System.out.print("caw: " + caw.toString());

   System.out.println();

   // By using reset() method isto reset the
   // caw stream 
   caw.reset();

   // Define CharSequence again
   cs = "Java Programming!!!!";

   // By using append() method is to
   // append new cs to the caw after calling
   // reset()
   caw.append(cs);

   // By using toString() method is 
   // to represent the caw as a string
   System.out.print("caw.reset(): " + caw.toString());

  } catch (Exception ex) {
   System.out.println(ex.toString());

  } finally {

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

Output

caw: Java World!!!
caw.reset(): Java Programming!!!!
