The program is written 3 files namely :RMI.java , RMIserver.java, RMIclient.java. This program implements RMI concept in java .
The Java Remote Method Invocation Application Programming Interface, or Java RMI, is a Java API that performs the object-oriented equivalent of remote procedure calls , with support for direct transfer of serialized Java objects and distributed garbage collection.
CODE:
RMI.java
import java.rmi.*;
public interface RMI extends Remote
{
void receiveMessage(String x) throws RemoteException;
}
RmiServer.java
import java.rmi.*;
import java.rmi.registry.*;
import java.rmi.server.*;
import java.net.*;

import java.io.*;
class student
{
int rn;
void getNumber(int n)
{
rn = n;
}

Validation is very important when we deal with anything processing on web. The data must be validated before it is entered into the database. Validation could be on server side as well as client side. We are going to focus on validation using java script on the client side.With The below code you can validate Names which is a string , Age which is a number and a email which has syntax such as email@email.com.
To run this code you just need a java script enabled browser to test.
copy the code and rename the file with .html extension.
Code:(Put it into text file and rename the file with .html extension)

Here is the code in C++ for simplex method problem .This code is well tested for number of inputs .
You need VB 6 or TURBO C complier to run this code.
PROGRAM:
#include <stdio.h>#include <math.h>
#define CMAX 10 #define VMAX 10
int NC, NV, NOPTIMAL,P1,P2,XERR; double TS[CMAX][VMAX];
void Data() { double R1,R2; char R; int I,J; printf("\n SIMPLEX METHOD\n\n"); printf(" MAXIMIZE (Y/N) ? "); scanf("%c", &R); printf("\n NUMBER OF VARIABLES OF THE FUNCTION ? "); scanf("%d", &NV); printf("\n NUMBER OF CONSTRAINTS ? "); scanf("%d", &NC); if (R == 'Y' || R=='y') R1 = 1.0; else R1 = -1.0; printf("\n INPUT COEFFICIENTS OF THE FUNCTION:\n"); for (J = 1; J<=NV; J++) { printf(" #%d ? ", J); scanf("%lf", &R2);...
