Returns the current size of the buffer.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    String str = "from java2s.com!";

    CharArrayWriter chw = new CharArrayWriter();

    // create destination character array writer
    CharArrayWriter chwd = new CharArrayWriter();

    chw.write(str);//  ww  w.j  a  v a  2  s  .co  m

    chw.writeTo(chwd);

    // print the destination buffer content as string
    System.out.println(chwd.toString());
    System.out.println(chwd.size());

}
