  • Constructor Summary

    Constructors

    Creates a FileInputStream to read from an existing file represented by the File object file.

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

    Creates a FileInputStream to read from an existing file named by the path name name.

  • Method Summary

    int

    available()

    Returns an estimate of the number of remaining bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.

    void

    close()

    Closes this file input stream and releases any system resources associated with the stream.

    Returns the unique FileChannel object associated with this file input stream.

    getFD()

    Returns the FileDescriptor object that represents the connection to the actual file in the file system being used by this FileInputStream.

    int

    read()

    Reads a byte of data from this input stream.

    int

    read(byte[] b)

    Reads up to b.length bytes of data from this input stream into an array of bytes.

    int

    read(byte[] b, int off, int len)

    Reads up to len bytes of data from this input stream into an array of bytes.

    byte[]

    readNBytes(int len)

    Reads up to a specified number of bytes from the input stream.

    long

    skip(long n)

    Skips over and discards n bytes of data from the input stream.

    Methods declared in class InputStream

    mark, markSupported, nullInputStream, readAllBytes, readNBytes, reset, skipNBytes, transferTo

    void

    mark(int readlimit)

    Marks the current position in this input stream.

    boolean

    Tests if this input stream supports the mark and reset methods.

    Returns a new InputStream that reads no bytes.

    byte[]

    Reads all remaining bytes from the input stream.

    int

    Reads the requested number of bytes from the input stream into the given byte array.

    void

    Repositions this stream to the position at the time the mark method was last called on this input stream.

    void

    Skips over and discards exactly n bytes of data from this input stream.

    long

    Reads all bytes from this input stream and writes the bytes to the given output stream in the order that they are read.

    Methods declared in class Object

    clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

    Creates and returns a copy of this object.

    boolean

    Indicates whether some other object is "equal to" this one.

    protected void

    Deprecated, for removal: This API element is subject to removal in a future version.

    Returns the runtime class of this Object.

    int

    Returns a hash code value for this object.

    final void

    Wakes up a single thread that is waiting on this object's monitor.

    final void

    Wakes up all threads that are waiting on this object's monitor.

    Returns a string representation of the object.

    final void

    Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

    final void

    wait(long timeoutMillis)

    Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

    final void

    wait(long timeoutMillis, int nanos)

    Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
