- void print ()
- void println()
- void newLine(
- void clear()
- void clearBuffer()
- void flush()
- boolean isAutoFlush()
- int getBufferSize()
- int getRemaining()
Void print () -:This method is written to String for output without newline character (ln). For example
out.print(“Out Implicit Object - netnic”);
void println()-: String is written to output with this method newline character (ln). For example
<%
out.println("Hello netnic");
out.println("Hello users");
%>
void newLine()-: This method It adds newline to the output. For example of new line methods

out.print("Hello netnic");
out.clear();
%>
void clearBuffer() -:The clearBuffer () method is used to clear the buffer from the output. If the buffer is already flush, the exception is not thrown by this method. For example ..
<%
if (out.getBufferSize() != 0){ out.clearBuffer();
}
%>
void flush()-:The flush () method clears the buffer in the same way as the clear () method. But it writes data to output before flush it. For example
<% out.flush(); %> <jsp:forward page="myhtmlfile.html" />
boolean isAutoFlush()-:isAutoFlush () method used output buffer; Boolean value returns by checking whether it has been flushed automatically or not. for example..
<%@ page autoFlush="true" %> <% out.print(out.isAutoFlush()); %>
int getBufferSize() -:This method returns the size of the output buffer to byte. For example
<%@ page buffer="5kb" %>
<% out.print("Buffer Size : " + out.getBufferSize()/1024 + "kb"); %>
int getRemaining()-: getRemaining () method returns empty output buffer to byte. For example ..
<%@ page buffer="5kb" %>
<% out.print("Buffer Size : " + out.getRemaining()/1024 + "kb"); %>
