倒,真的是很简单，不会看api啊：（
read
public int read()
throws IOExceptionRead a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.
Subclasses that intend to support efficient single-character input should override this method.Returns:
The character read, as an integer in the range 0 to 65535 (0x00-0xffff), or -1 if the end of the stream has been reached
Throws:
IOException - If an I/O error occurs
为什么是*Reader？指的事reader派生出来的类？嘿嘿，那有没有重载就要看不同的类了

public int read()
throws IOException
Read a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.
Subclasses that intend to support efficient single-character input should override this method.
Returns:
The character read, as an integer in the range 0 to 65535 (0x00-0xffff), or -1 if the end of the stream has been reached
Throws:
IOException - If an I/O error occurs--------------------------------------------------------------------------------read
public int read(char[] cbuf)
throws IOException
Read characters into an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached. Parameters:
cbuf - Destination buffer
Returns:
The number of characters read, or -1 if the end of the stream has been reached
Throws:
IOException - If an I/O error occurs--------------------------------------------------------------------------------read
public abstract int read(char[] cbuf,
int off,
int len)
throws IOException
Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached. Parameters:
cbuf - Destination buffer
off - Offset at which to start storing characters
len - Maximum number of characters to read
Returns:
The number of characters read, or -1 if the end of the stream has been reached
Throws:
IOException - If an I/O error occurs
看Returns:
The character read, as an integer in the range 0 to 65535 (0x00-0xffff), or -1 if the end of the stream has been reached
就知道这个函数返回什么了
来了这么多人,我就顺便问问--它与C#的system.io中的各reader的Read()方法有什么不同,没试过课千万不要做答啊!
原来看来一样的东西会有很多区别的啊!
