CharArrayWriter

public class CharArrayWriter extends Writer

This class implements a character buffer that can be used as an Writer. The buffer automatically grows when data is written to the stream. The data can be retrieved using toCharArray() and toString().

Note: Invoking close() on this class has no effect, and methods of this class can be called after the stream has closed without generating an IOException.

Field Summary

protected char[] buf The buffer where data is stored.
protected int count The number of chars in the buffer.
