2015-06-21T03:23:00.002-07:00

Given a date and calculate day of the week:

import java.util.*;

public class Datetoday {

final static String[] WEEK_DAYS = {

"Saturday", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday",

"Friday"

};

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter the date in dd/mm/yyyy form: ");

String[] partofdate = input.nextLine().split("/");

int d = Integer.parseInt(partofdate[0]);

int m = Integer.parseInt(partofdate[1]);

int y = Integer.parseInt(partofdate[2]);

if (m < 3) {

m += 12;

y -= 1;

}

int k = y % 100;

int j = y / 100;

int day = ((d + (((m + 1) * 26) / 10) + k + (k / 4) + (j / 4)) +

(5 * j)) % 7;

System.out.println("That date was " + WEEK_DAYS[day] + ".");

Websphere Application Server Basic Stuffs Outlined

2015-03-28T05:14:00.003-07:00

Today we will be discussing on one of the heavily used Application Server that accepts not only HTTP/HTTPS request but also dynamic request like server programming and various calls like IIOP,RMI,Socket Server communication etc.

Websphere Application Server an IBM Product

WebSphere Virtual Enterprise has the ability to prioritize requests based on administrator-defined rules to adjust to server response times according to Service Level Agreements and application priority. WebSphere’s administration console is really good, easy to maintain one's application and for security setting.There are many “automatic” things that are done in “autopilot” mode by WVE that greatly simplify administration and improve qualities of services.Websphere is a nice choice if your needs fit a high end architecture products such as you are building an Telecommunication Softwares etc.

It is one of finest and Expensive product but it is best in performance,Scalibility,Automatic migrations are also possible with so many enhanced Features.

---2 QUESTION--

· Create a database named ‘ Employee’.

· Use the database ‘Employee’ and create a table ‘Emp’ with attributes ‘ename’,’ecity’,’salary’,’enumber’,’eaddress’,’depttname’.

· Create another table ‘Company’ with attributes ‘cname’,’ ccity’,’numberof emp’,’empnumber’ in the database ‘Employee’.

create database employee
use employee
create table emp
(
ename varchar(20),ecity varchar(20),salary float,enumber int,eaddres varchar(40),deptname varchar(20));
Create table Company
