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);/*w w w.  j  av a2 s.c o  m*/

    chw.writeTo(chwd);

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

}

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

    chw.write(str);//from  ww  w .  j  ava  2s.co m

    chw.writeTo(chwd);

    // print the destination buffer content as string
