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) throws Exception {
    FileInputStream fin = new FileInputStream("C:/Array.txt");
    DataInputStream din = new DataInputStream(fin);

    byte b[] = new byte[10];
    din.read(b);/*from   w  w  w . ja va 2 s  .co  m*/
    din.close();
}

From source file:Main.java

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

    short s = din.readShort();
    System.out.println("short : " + s);
    din.close();/*from w  w w .  jav  a  2s.  c  om*/
}

From source file:Main.java

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

    int i = din.readUnsignedByte();
    System.out.println("Unsinged byte value : " + i);
    din.close();/*from w  ww.j  a  va2s.  c om*/
}

From source file:Main.java

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

    float f = din.readFloat();
    System.out.println("float : " + f);
    din.close();/*  ww  w .j  a v a  2 s .  c om*/
}

From source file:Main.java

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

    // skip bytes from file input stream
    fis.skip(4);/*w  w  w .  jav  a2s.co m*/

    // 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 {

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

    int i = fis.read();

    char c = (char) i;

    System.out.println(c);// w  ww .ja  v a  2  s  . c  om

    // close file input stream
    fis.close();

}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    FileInputStream fileIn = new FileInputStream("data.txt");
    DataInputStream dataIn = new DataInputStream(fileIn);
    System.out.println(dataIn.readUTF());
    int counter = dataIn.readInt();
    double sum = 0.0;
    for (int i = 0; i < counter; i++) {
        double current = dataIn.readDouble();
        System.out.println("Just read " + current);
        sum += current;/*  w  w  w.j  a v  a  2  s  . c o  m*/
    }
    System.out.println("\nAverage = " + sum / counter);
    dataIn.close();
    fileIn.close();
}

From source file:Load.java

public static void main(String args[]) throws Exception {
    Properties p = new Properties();
    p.load(new FileInputStream("colon.txt"));
    p.getProperty("foo");
}

From source file:Main.java

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

    // read and print characters one by one
    System.out.println("Char : " + (char) is.read());
    System.out.println("Char : " + (char) is.read());
    System.out.println("Char : " + (char) is.read());

    // mark is set on the input stream
    is.mark(0);/*from  w  w  w .  ja va 2 s.com*/

    System.out.println("Char : " + (char) is.read());
    System.out.println("Char : " + (char) is.read());

    if (is.markSupported()) {
        // reset invoked if mark() is supported
        is.reset();
        System.out.println("Char : " + (char) is.read());
        System.out.println("Char : " + (char) is.read());
    }
    is.close();
}
