FileWriter

Class Overview

Convenience class for writing character files. The constructors of this class assume that the default character encoding and the default byte-buffer size are acceptable. To specify these values yourself, construct an OutputStreamWriter on a FileOutputStream.

Whether or not a file is available or may be created depends upon the underlying platform. Some platforms, in particular, allow a file to be opened for writing by only one FileWriter (or other file-writing object) at a time. In such situations the constructors in this class will fail if the file involved is already open.

FileWriter is meant for writing streams of characters. For writing streams of raw bytes, consider using a FileOutputStream.

Summary

[Expand] Inherited Fields
From class java.io.Writer protected Object lock The object used to synchronize operations on this stream.

[Expand] Inherited Methods
From class java.io.OutputStreamWriter void close() Closes the stream, flushing it first. void flush() Flushes the stream. String getEncoding() Returns the name of the character encoding being used by this stream. void write(char[] cbuf, int off, int len) Writes a portion of an array of characters. void write(String str, int off, int len) Writes a portion of a string. void write(int c) Writes a single character.
From class java.io.Writer Writer append(CharSequence csq) Appends the specified character sequence to this writer. Writer append(CharSequence csq, int start, int end) Appends a subsequence of the specified character sequence to this writer. Writer append(char c) Appends the specified character to this writer. abstract void close() Closes the stream, flushing it first. abstract void flush() Flushes the stream. void write(char[] cbuf) Writes an array of characters. void write(String str) Writes a string. abstract void write(char[] cbuf, int off, int len) Writes a portion of an array of characters. void write(String str, int off, int len) Writes a portion of a string. void write(int c) Writes a single character.
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() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, 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 timeout) 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.
From interface java.io.Closeable abstract void close() Closes this stream and releases any system resources associated with it.
From interface java.io.Flushable abstract void flush() Flushes this stream by writing any buffered output to the underlying stream.
From interface java.lang.Appendable abstract Appendable append(CharSequence csq) Appends the specified character sequence to this Appendable. abstract Appendable append(CharSequence csq, int start, int end) Appends a subsequence of the specified character sequence to this Appendable. abstract Appendable append(char c) Appends the specified character to this Appendable.
