FileReader

Class Overview

A specialized Reader that reads from a file in the file system. All read requests made by calling methods in this class are directly forwarded to the equivalent function of the underlying operating system. Since this may induce some performance penalty, in particular if many small read requests are made, a FileReader is often wrapped by a BufferedReader.

[Expand] Inherited Methods
From class java.io.InputStreamReader void close () Closes this reader. String getEncoding () Returns the canonical name of the encoding used by this writer to convert characters to bytes, or null if this writer has been closed. int read () Reads a single character from this reader and returns it as an integer with the two higher-order bytes set to 0. int read (char[] buffer, int offset, int count) Reads up to count characters from this reader and stores them at position offset in the character array buffer . boolean ready () Indicates whether this reader is ready to be read without blocking.
From class java.io.Reader abstract void close () Closes this reader. void mark (int readLimit) Sets a mark position in this reader. boolean markSupported () Indicates whether this reader supports the mark() and reset() methods. int read () Reads a single character from this reader and returns it as an integer with the two higher-order bytes set to 0. abstract int read (char[] buffer, int offset, int count) Reads up to count characters from this reader and stores them at offset in the character array buffer . int read ( CharBuffer target) Reads characters and puts them into the target character buffer. int read (char[] buffer) Reads characters from this reader and stores them in the character array buffer starting at offset 0. boolean ready () Indicates whether this reader is ready to be read without blocking. void reset () Resets this reader's position to the last mark() location. long skip (long charCount) Skips charCount characters in this reader.
From class java.lang.Object Object clone () Creates and returns a copy of this Object . boolean equals ( Object o) Compares this instance with the specified object and indicates if they are equal. void finalize () Invoked when the garbage collector has detected that this instance is no longer reachable. final Class <?> getClass () Returns the unique instance of Class that represents this object's class. int hashCode () Returns an integer hash code for this object. final void notify () Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. final void notifyAll () Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. String toString () Returns a string containing a concise, human-readable description of this object. final void wait () Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object. final void wait (long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait (long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
From interface java.io.Closeable abstract void close () Closes the object and release any system resources it holds.
From interface java.lang.AutoCloseable abstract void close () Closes the object and release any system resources it holds.
From interface java.lang.Readable abstract int read ( CharBuffer cb) Reads characters into the specified CharBuffer .
