read	back to summary
public int read(char[] buff, int off, int len) throws IOException Implements abstract java.io.Reader.read. Doc from java.io.Reader.read. Reads 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. If `len` is zero, then no characters are read and `0` is returned; otherwise, there is an attempt to read at least one character. If no character is available because the stream is at its end, the value `-1` is returned; otherwise, at least one character is read and stored into `cbuf`. Parameters buff:char[] Destination buffer off:int Offset at which to start storing characters len:int Maximum number of characters to read Returns:int The number of characters read, or -1 if the end of the stream has been reached Annotations @Override Exceptions IOException: If an I/O error occurs

public int read(char[] buff, int off, int len) throws IOException

Implements abstract java.io.Reader.read.

Doc from java.io.Reader.read.

Reads 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

buff:char[]: Destination buffer
off:int: Offset at which to start storing characters
len:int: Maximum number of characters to read

Returns:int

The number of characters read, or -1 if the end of the stream has been reached
