Creates a buffered character-output stream that uses a default-sized output buffer.

Usage

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);/* w  w  w  .ja v a 2 s.c om*/

    bw.flush();

    StringBuffer sb = sw.getBuffer();

    System.out.println(sb);

}

From source file:Main.java

public static void main(String[] args) throws Exception {
    String multilineString = "This is line 1\nthis is line 2\nthis is last line";

    FileWriter fileWriter = new FileWriter("multiline.txt", true);

    BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);
    bufferedWriter.write(multilineString + "\n");
    bufferedWriter.flush();//from w  ww .j ava  2s .  c o m
    bufferedWriter.close();
    fileWriter.close();
}

From source file:Main.java

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

    out.flush();// ww w  .j  a  v a2s . co  m
    in.close();
    out.close();
}

From source file:Main.java

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

    BufferedWriter bw = new BufferedWriter(sw);

    // writing string to writer
    bw.write(str, 1, 4);/*from ww  w  .j ava 2s.c om*/

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

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

    System.out.println(sb);

}
