Actually i know how to create an independent database and how to update it manually. But i just
want to know that how can i make that update thing automatically. Like suppose if i give somekind of
username and password to members of my site and i wish to have them updated , like addition ,
deletion or changes in password, to be automatic how can i do that. i have a rough idea that it can
be done with the help of Java and jdbc but i don't know exactly. I m good at programming
languages C and Java....

I’m probably the only person that is able to do so much with Java3D and yet still can't
even get some of the Java basics down. Anyway is it (and if so how is it) possible to make a
variable editable and readable in multiple class files? It seems like this should be an easy
question to answer, but here is a little code to help you understand what I am talking about. CODE
public class test extends Applet{  public int Col = 0;      if(Col==1){     } } class
TestB extends Behavior {    if(collision == true){   Col = 0;  }else{   Col = 1;  } } Tha...

The purpose of this tutorial is to explain how to create a Java applet. A Java applet is simply a
Java program that runs on a webpage. This tutorial assumes that you have a basic understanding of
Java. If you don't, I would suggest reading a tutorial on Java first. In this tutorial I
will be using Java 1.5 (or 5.0). If you don't have it you can download it from Sun . The
classes and methods used in this tutorial may work for other versions of Java, but I don't know
for sure. During this tutorial I would suggest opening up Java's online documen...

Dear friends I came to know that one can build exe files from java application. How this is
possible? According to me there is no such method in java to cerate exe files. However Microsoft
used to provide a free system development kit (SDK), for Java, which includes the jexegen tool. But
one need install Microsoft Java Virtual Machine to run such application. Some people suggest

Hello everybody I wrote this program a few months back when I wan learning JAVA.I haven't
learned java yet though because its to vast. The program is console based. It uses the util package
of java in a great way. It keeps record in a flat file. You should create a Data file called
phone.dat in same folder where phone.java is kept. So here is the code:-(phone.java) CODE
import java .io .*; import java .util .*; import java.awt.event.*; public class phone {
    public void new_record()     {        String id,name,city,add,number,total,list;

Does any one have experience or solution for this? Here is what I want: I need to develop an
application that would be running on only one computer which is not networked in anyway. It will be
a standalone PC and it would not have internet connection. The application I need to develop would
most probably be written in Java - and it may go for Java swing components. The application would
need a database. I need to install the database on the same computer. What open source or free
database options do I have that would let me develop an application using Java on it?...

Hello Java people! I'm starting to work more on java this spring (university stuff) and I think
I need a proper IDE. So far my java programming has been in little scale so editor and command line
compiling has worked just fine. So I'm looking for a good, free IDE. It does not need to have
fancy features, just what you'd expect from an IDE. My previous experience on IDEs limits
pretty much to MS Visual Studio. I've also tried out Borland's builders but I've hated
them, granted they all were quite old versions. So what IDEs you use and what y...

Chandler choosed Python, arguing that Python is more open source than Java. Apache brought an open
source java to the market. Is Python covering so many domains than Java? Would it be possible to
code every kind of application with Python? For wich reason would you choose Python for an
application development?...

Is it just me ? I see very few Java Hosting Providers compared to the ones with ASP and PHP. Agreed
Java is the first choice in upscale environments, however being open and free, I thought I would
bump into many cost friendly Java Hosting providers, but in vein. It seems Microsoft still rules in
low end market. What should we look for from a Java Hosting Service Provider ? I have listed my
priorities in descending order. Please comment. 1) Look at the file storage and band width
requirement. 20 MB disk space is decent enough size to start with. Band Widths provided b...

 I have been using the picking tool with setShapeCylinderSegment (this returns infinit results but
is capped). It works just fine for me (in terms of what it does) and it wasn't until just
recently I noticed that it has been causing my program to spike the memory. I have looked through
Google to see the problem and apparently it is caused a memory leak. I have tried to solve it by
simply setting all the variables to null after they are used but this doesn't help. Is there
something I can do to or a free software I can use to find the exact variable that is causin...

This question is not as easy as you may think to answer, so please read my post completely before
replying.    I am trying to make an applet that responds to mouse movements but I always have
trouble. I can make it work just fine if I find the distance from a point using getX(); or
getXOnScreen(); but that's not what I want to do. I want to get the direct input from the mouse.
Why? Because when the mouse (cursor) hits the edge of the screen its position stays the same even
when you move it. I have tried using a robot to keep the mouse in the center of the screen (se...

Java was the first programming language that I learned on my own...no teachers, no friends, just me
and the internet. One of the best aspects of Java is the heavy documentation provided by Sun and
every other Java developer out there. Here is a link to a site that lists loads of examples of Java
code. http://javaalmanac.com/egs/ ? They have examples of setting up a JDBC/ODBC connection for
database use, creating ZIP files for archival purposes, and simply showing you how to use vectors.
This site is great for learning the basics and building applications on top of i...

 I have looked all over the web for a solution and none of them seem to work. Anyway, I am trying to
load a 3d object onto a scene with a java applet and I get the following error. CODE
java.security.AccessControlException: access denied (java.io.FilePermission object.obj read) I
think that it has to do with my java.policy permissions, but I cant find anything that will fix it.
Has anyone ever seen this error and/or know a solution to it? I am looking for a solution that will
work on other people's computers without them downloading anything extra (other then ...

The Java Programming Manual Chapter 0: Introduction. What Java is and what it is not Java is
an object oriented programming language that has evolved from and to substitute the C and C++
programming languages. But why? The main reason for Java to have evolved is "platform
independence" we shall come to this part later. When a programming language is designed, certain
trade offs have to be made. 1) Ease of use versus Power 2) Efficiency versus Safety 3) Rigidity
versus Extensibility This also gives a more or less accurate comparison of C++ versus Java Java ha...

Ok, right now I am currently using eclipse, however I can change to whatever if there is something
else that would be better for this. But I have made a number of java applications, but they all
simply use the command line for doing their user input and output. However, I have been interested
in learning how to program graphical user interfaces in java, and was wondering if somebody could
point me in the right direction, with some easy to understand and follow tutorials. Also, once I
have done that, what about making a java program that can be easily executed? (I know t...

Hey i have been searching google and websites to find the answer to my question but i just get
blasted with a bunch of code that isn't explained... So i would like to know how, in either
php or java how i would get something to count down to a certain time, but not specifically a time,
more like count down in days, hours, minutes and seconds and not require a refresh... like it count
downs on the page every second... And that i can specify the days, hours etc in the start of the
function such as function countdown($days, $hours, $minutes, $seconds){ } Thanks...
