Class CharArrayWriterjava.lang.Object
public class CharArrayWriter extends WriterThis 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(). 该类实现了一个字符缓冲，可以作为Writer使用。当数据写入该流时，缓冲会自动增长。 使用toCharArray()和toString()可以获取数据。
Since: JDK1.1 Field Summary
protected char[]
The buffer where data is stored. 数据存入的缓冲。
protected int
The number of chars in the buffer. 缓冲中的字符数。
Fields inherited from class java.io.Writer
Constructor Summary
Creates a new CharArrayWriter. 创建一个CharArrayWriter。
CharArrayWriter(int initialSize)
Creates a new CharArrayWriter with the specified initial size. 创建一个指定初始大小的CharArrayWriter。
Method Summary
void
close()
Close the stream. 关闭流。
void
flush()
Flush the stream. 刷新流。
void
reset()
Resets the buffer so that you can use it again without throwing away the already allocated buffer. 重置缓冲，可以使你再次使用，而不用抛出已分配的缓冲。
int
size()
Returns the current size of the buffer. 返回缓冲的当前大小。
char[]
Returns a copy of the input data. 返回输入数据的拷贝。
toString()
Converts input data to a string. 将输入数据转换成字符串。
void
,]write(char[] c, int off, int len)
Writes characters to the buffer. 向缓冲写入字符。
void
write(int c)
Writes a character to the buffer. 向缓冲写入一个字符。
void
write(String str, int off, int len)
Write a portion of a string to the buffer. 向缓冲写入一段字符串。
void
Writes the contents of the buffer to another character stream. 将缓冲的内容写入另一个字符流。

throws IOException
Writes the contents of the buffer to another character stream. 将缓冲的内容写入另一个字符流。
Parameters: out - the output stream to write to 写入的输出流 Throws: IOException - If an I/O error occurs. 如果I/O错误发生时抛出。resetpublic void reset()
Resets the buffer so that you can use it again without throwing away the already allocated buffer. 重置缓冲，可以使你再次使用，而不用抛出已分配的缓冲。

Flush the stream. 刷新流。
Specified by: flush in class Writerclosepublic void close()
Close the stream. This method does not release the buffer, since its contents might still be required. 关闭流。该方法不释放缓冲，因为它的内容可能仍有需要。
