Usage

From source file:Main.java

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

    String letters = "from java2s.com";

    StringWriter sw = new StringWriter();

    BufferedWriter bw = new BufferedWriter(sw);

    for (char c : letters.toCharArray()) {

        bw.append(c);/*from   ww  w .j a v  a 2s .c o m*/

        bw.flush();

        System.out.println(sw.getBuffer());
    }

}

From source file:Main.java

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

    char[] cbuf = "from java2s.com".toCharArray();

    StringWriter sw = new StringWriter();

    BufferedWriter bw = new BufferedWriter(sw);

    bw.write(cbuf, 2, 5);//from  w ww .  ja  v  a2  s .  c  o m

    bw.flush();

    StringBuffer sb = sw.getBuffer();

    System.out.println(sb);

}

From source file:Main.java

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

    String str = "from java2s.com!";

    // create string writer
    StringWriter sw = new StringWriter();

    // create buffered writer
    BufferedWriter bw = new BufferedWriter(sw);

    // writing string to writer
    bw.write(str, 1, 4);/*from  w w w  .  j a v a2 s .co  m*/

    // forces out the characters to string writer
    bw.flush();

    // string buffer is created
    StringBuffer sb = sw.getBuffer();

    System.out.println(sb);
