What do you meant by Runtime Polymorphism?

Answer

Runtime polymorphisms means the code is called at run time
according to need or given conditions.

suppose there r two methods namely Add() one in super class
and other is in sub class.both have the same name and same

so we have to choose that which method from them should
called at run time i.e. of super class or of sub class.

It can be achieved through the use of virtual functions.

What is the requirement in MIMD ?

Answer

In computing, MIMD (Multiple Instruction stream, Multiple
Data stream) is a technique employed to achieve parallelism.
Machines using MIMD have a number of processors that
function asynchronously and independently. At any time,
different processors may be executing different instructions
on different pieces of data. MIMD architectures may be used
in a number of application areas such as computer-aided
design/computer-aided manufacturing, simulation, modeling,
and as communication switches. MIMD machines can be of
either shared memory or distributed memory categories. These
classifications are based on how MIMD processors access
memory. Shared memory machines may be of the bus-based,
extended, or hierarchical type. Distributed memory machines
may have hypercube or mesh interconnection schemes.

Question { Oracle, 11838 }

What is the difference between in-proc and out-of-proc?

Answer

An in-proc is one which runs in the same process area as
that of the client giving the advantage of speed but the
disadvantage of stability because if it crashes it takes the
client application also with it.Out-of-proc server is one
which works outside the clients memory thus giving stability
to the client, but we have to compromise a bit on speed.

DLL's are In-proc and EXE's are Out-of-Proc servers.

Question { 4196 }

what is the Need of zorder method?

Answer

Three graphical layers are associated with forms and
containers. The back layer is the drawing space where the
results of the graphics methods are displayed. Next is the
middle layer where graphical objects and Label controls are
displayed. The front layer is where all nongraphical
controls like Command Button, CheckBox, or ListBox are
displayed. Anything contained in a layer closer to the front
covers anything contained in the layer(s) behind it. ZOrder
arranges objects only within the layer where the object is
displayed.

Question { Sify, 6905 }

How can I embed a java programme in PHP file and what
changes have to be done in PHP.ini file?

Answer

There are two possible ways to bridge PHP and Java: you can
either integrate PHP into a Java Servlet environment, which
is the more stable and efficient solution, or integrate Java
support into PHP. The former is provided by a SAPI module
that interfaces with the Servlet server, the latter by this
Java extension.
The Java extension provides a simple and effective means for
creating and invoking methods on Java objects from PHP. The
JVM is created using JNI, and everything runs in-process.

Example Code:

getProperty('java.version') . ''; echo 'Java vendor=' .
$system->getProperty('java.vendor') . ''; echo 'OS=' .
$system->getProperty('os.name') . ' ' .
$system->getProperty('os.version') . ' on ' .
$system->getProperty('os.arch') . ' '; // java.util.Date
example $formatter = new Java('java.text.SimpleDateFormat',
"EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz"); echo
$formatter->format(new Java('java.util.Date')); ?>

The behaviour of these functions is affected by settings in
php.ini.
