Examples of java.io.Writer

java.io.Writer
Abstract class for writing to character streams. The only methods that a subclass must implement are write(char[], int, int), flush(), and close(). Most subclasses, however, will override some of the methods defined here in order to provide higher efficiency, additional functionality, or both. @see Writer @see BufferedWriter @see CharArrayWriter @see FilterWriter @see OutputStreamWriter @see FileWriter @see PipedWriter @see PrintWriter @see StringWriter @see Reader @version 1.29, 05/11/17 @author Mark Reinhold @since JDK1.1
