Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:Main.java

public static void main(String[] args) {

    String s = "from java2s.com!";

    try {//  w ww  . j a v  a  2s .  c om

        OutputStream os = new FileOutputStream("test.txt");
        OutputStreamWriter writer = new OutputStreamWriter(os, java.nio.charset.StandardCharsets.UTF_8);

        FileInputStream in = new FileInputStream("test.txt");

        writer.write(s, 0, 5);

        writer.flush();

        for (int i = 0; i < 5; i++) {
            System.out.print((char) in.read());
        }
        writer.close();
        in.close();
    } catch (Exception ex) {
