Creates a buffering character-input stream that uses a default-sized input buffer.

Usage

From source file:Main.java

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

    String s = "from java2s.com";

    StringReader sr = new StringReader(s);

    // create new buffered reader
    BufferedReader br = new BufferedReader(sr);

    // Destination source is created
    CharBuffer target = CharBuffer.allocate(s.length());

    // ready is invoked to test if character stream is ready
    if (br.ready()) {
        br.read(target);/*w  w w.j  av  a 2s  . com*/
    }
    System.out.print(target.array());

}

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
    System.out.println(stdin.readLine());
    BufferedReader in = new BufferedReader(new FileReader("Main.java"));
    String s, s2 = new String();
    while ((s = in.readLine()) != null)
        s2 += s + "\n";
    in.close();/* w ww . j a v  a  2s  .  co  m*/
    StringReader in1 = new StringReader(s2);
    int c;
    while ((c = in1.read()) != -1)
        System.out.print((char) c);
    BufferedReader in2 = new BufferedReader(new StringReader(s2));
    PrintWriter out1 = new PrintWriter(new BufferedWriter(new FileWriter("IODemo.out")));
    int lineCount = 1;
    while ((s = in2.readLine()) != null)
        out1.println(lineCount++ + ": " + s);
    out1.close();
}
