CharArrayWriter Class size() method

• size() method is available in java.io package.
• size() method is used to get the current size of this buffer (CharArrayWriter).
• size() 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.
• size() method does not throw an exception at the time of returning the current size.

Syntax:

    public int size();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is int, it returns the current size of this stream.

Example:

// Java program to demonstrate the example 
// of int size() method of CharArrayWriter

import java.io.*;
public class SizeOfCAW {
 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 size() method isto return
   // the size of this stream
   int size = caw.size();

   // Display size of the stream 
   System.out.print("caw.size(): " + size);
  } 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.size(): 13
