Public constructors
`PushbackReader(Reader in)` Creates a new pushback reader with a one-character pushback buffer.
`PushbackReader(Reader in, int size)` Creates a new pushback reader with a pushback buffer of the given size.

Public methods
`void`	`close()` Closes the stream and releases any system resources associated with it.
`void`	`mark(int readAheadLimit)` Marks the present position in the stream.
`boolean`	`markSupported()` Tells whether this stream supports the mark() operation, which it does not.
`int`	`read()` Reads a single character.
`int`	`read(char[] cbuf, int off, int len)` Reads characters into a portion of an array.
`boolean`	`ready()` Tells whether this stream is ready to be read.
`void`	`reset()` Resets the stream.
`long`	`skip(long n)` Skips characters.
`void`	`unread(char[] cbuf, int off, int len)` Pushes back a portion of an array of characters by copying it to the front of the pushback buffer.
`void`	`unread(char[] cbuf)` Pushes back an array of characters by copying it to the front of the pushback buffer.
`void`	`unread(int c)` Pushes back a single character by copying it to the front of the pushback buffer.
