Class Overview

A file input stream is an input stream for reading data from a File.

Summary

Public Constructors
	FileInputStream(String path) Creates a FileInputStream by opening a connection to an actual file, the file at the indicated path.
	FileInputStream(File file) Creates a FileInputStream by opening a connection to an actual file, the file named by the File object file in the file system.

Public Methods
int	read() Reads the next byte of data from the input stream.

Inherited Methods

From class java.io.InputStream

int	available() Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.
void	close() Closes this input stream and releases any system resources associated with the stream.
synchronized void	mark(int readlimit) Marks the current position in this input stream.
boolean	markSupported() Tests if this input stream supports the `mark` and `reset` methods.
abstract int	read() Reads the next byte of data from the input stream.
int	read(byte[] b, int off, int len) Reads up to `len` bytes of data from the input stream into an array of bytes.
int	read(byte[] b) Reads some number of bytes from the input stream and stores them into the buffer array `b`.
synchronized void	reset() Repositions this stream to the position at the time the `mark` method was last called on this input stream.
long	skip(long n) Skips over and discards `n` bytes of data from this input stream.

From class java.lang.Object

boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
final Class<?>	getClass() Returns the runtime class of an object.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait(long timeout, int nanos) Causes current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
final void	wait() Causes current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public Constructors

public FileInputStream (String path)

Creates a FileInputStream by opening a connection to an actual file, the file at the indicated path.

Parameters

path	the path of the file to open

Throws

	IOException} if the file at the specified path cannot be opened
IOException

public FileInputStream (File file)

Creates a FileInputStream by opening a connection to an actual file, the file named by the File object file in the file system.

Parameters

file	the file to be opened for reading

Throws

	IOException} if the file cannot be opened
IOException

Public Methods

public int read ()

Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

A subclass must provide an implementation of this method.

Returns

the next byte of data, or -1 if the end of the stream is reached.

Throws

IOException
