JSP built-in object values out object and some common methods of it

Out object:

An Out object is an instance of the JspWriter class and is an object commonly used to output content to the client.

Common methods are as follows:

void println () prints a string to the client

void Clear () clears the contents of the buffer and throws an exception if called after flush

void Clearbuffer (); Clears the contents of the buffer if the call does not throw an exception after flush

void Flush () outputs the buffer contents to the client

int GetBufferSize () returns the buffer in the size of the number of bytes, or 0 if no buffer is set

int getremaining () returns how much of the buffer is left available

Boolean Isautoflush () returns whether the buffer is full, automatically emptied or throws an exception

void Close () to close the output stream

int allbuf=out.getbuffersize (); Gets the size of the buffer
int remainbuf=out.getremaining ();//Gets the size of the remaining buffer
int usedbuf=allbuf-remainbuf;//already used buffer
