FileReader

public class FileReader
extends InputStreamReader

java.lang.Object
↳	java.io.Reader
	↳	java.io.InputStreamReader
		↳	java.io.FileReader

Convenience class for reading character files. The constructors of this class assume that the default character encoding and the default byte-buffer size are appropriate. To specify these values yourself, construct an InputStreamReader on a FileInputStream.

FileReader is meant for reading streams of characters. For reading streams of raw bytes, consider using a FileInputStream.

Inherited methods

From class



          java.io.InputStreamReader

`void`	`close()` Closes the stream and releases any system resources associated with it.
`String`	`getEncoding()` Returns the name of the character encoding being used by this stream.
`int`	`read()` Reads a single character.
`int`	`read(char[] cbuf, int offset, int length)` Reads characters into a portion of an array.
`boolean`	`ready()` Tells whether this stream is ready to be read.

From class



          java.io.Reader

`abstract void`	`close()` Closes the stream and releases any system resources associated with it.
`void`	`mark(int readAheadLimit)` Marks the present position in the stream.
`boolean`	`markSupported()` Tells whether this stream supports the mark() operation.
`int`	`read()` Reads a single character.
`abstract int`	`read(char[] cbuf, int off, int len)` Reads characters into a portion of an array.
`int`	`read(char[] cbuf)` Reads characters into an array.
`int`	`read(CharBuffer target)` Attempts to read characters into the specified character buffer.
`boolean`	`ready()` Tells whether this stream is ready to be read.
`void`	`reset()` Resets the stream.
`long`	`skip(long n)` Skips characters.

From class



          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `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 millis, int nanos)` Causes the 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 millis)` Causes the 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 the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

FileReader

added in API level 1

public FileReader (String fileName)

Creates a new FileReader, given the name of the file to read from.

Parameters
`fileName`	`String`: the name of the file to read from

Throws
`FileNotFoundException`	if the named file does not exist, is a directory rather than a regular file, or for some other reason cannot be opened for reading.

FileReader

added in API level 1

public FileReader (File file)

Creates a new FileReader, given the File to read from.

Parameters
`file`	`File`: the `File` to read from

Throws
`FileNotFoundException`	if the file does not exist, is a directory rather than a regular file, or for some other reason cannot be opened for reading.

FileReader

public FileReader (FileDescriptor fd)

Creates a new FileReader, given the FileDescriptor to read from.

Parameters
`fd`	`FileDescriptor`: the FileDescriptor to read from
