Document

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:MainClass.java

public static void main(String args[]) throws Exception {
    Properties p = new Properties();
    p.load(new FileInputStream("colon.txt"));
    p.list(System.out);/*w w  w .  java2s.  c  om*/
}

From source file:Main.java

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

    // new input stream created
    InputStream is = new FileInputStream("C://test.txt");

    // returns true if the mark()/reset() supported.
    boolean bool = is.markSupported();
    is.close();/*from  ww w  .  ja v a2 s  . c o m*/
    System.out.print(bool);

}

From source file:Main.java

public static void main(String[] a) {
    FileInputStream inputFile = null;
    try {/*w w w . j a va  2s . com*/
        inputFile = new FileInputStream("C:/myFile.txt");
    } catch (FileNotFoundException e) {
        e.printStackTrace(System.err);
    }
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    File file = new File("C:/String.txt");
    FileInputStream fin = new FileInputStream(file);

    byte fileContent[] = new byte[(int) file.length()];
    fin.read(fileContent);//from w ww  . j ava  2s. co m
    System.out.println(new String(fileContent));
}

From source file:Main.java

public static void main(String[] args) throws IOException {
    FileInputStream fis = new FileInputStream("C://test.txt");

    // get file descriptor
    FileDescriptor fd = fis.getFD();

    // tests if the file is valid
    boolean bool = fd.valid();

    System.out.println("Valid file: " + bool);

}

From source file:MainClass.java

public static void main(String[] args) throws Exception {
    FileChannel in = new FileInputStream("source.txt").getChannel(),
            out = new FileOutputStream("target.txt").getChannel();
    in.transferTo(0, in.size(), out);/*w  w w . j  a v a2  s . c  o m*/
    // Or:
    // out.transferFrom(in, 0, in.size());
}

From source file:Main.java

public static void main(String args[]) throws Exception {
    Properties prop = new Properties();
    FileInputStream fis = new FileInputStream("sampleprops.xml");
    prop.loadFromXML(fis);/*w  w  w.j a va  2s . c o m*/
    prop.list(System.out);
    System.out.println("\nThe foo property: " + prop.getProperty("foo"));
}

From source file:Main.java

public static void main(String[] args) throws IOException {
    FileInputStream fis = new FileInputStream(FileDescriptor.in);

    // skip bytes from file input stream
    fis.skip(4);/*from w  ww.  j a  v  a 2  s  .  com*/

    // read bytes from this stream
    int i = fis.read();

    // converts integer to character
    char c = (char) i;
    System.out.print("Character read: " + c);
}

From source file:Main.java

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

    int i = 0;//from w  w w.j a v a2s .c o m

    FileInputStream fis = new FileInputStream("C://test.txt");

    // read till the end of the stream
    while ((i = fis.read()) != -1) {
        // available bytes
        int available = fis.available();

        // convert integer to character
        char c = (char) i;

        System.out.println("Available: " + available);
        System.out.println("Read: " + c);
    }

}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    FileChannel srcChannel = new FileInputStream("srcFilename").getChannel();
    FileChannel dstChannel = new FileOutputStream("dstFilename").getChannel();

    dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
    srcChannel.close();/*from   w w  w. jav  a2 s  . c  o m*/
    dstChannel.close();
