There is a difference between high end and low end systems, but at some point you get diminishing returns.
So while there's a definite difference between $10 and $100 headphones, the difference between $100 and $100 headphones is a lot smaller.

the class changed, therefore any old serialised instances are now incompatible with the new class structure.

by simply installing a decent commercially available virus scanner.
Problem solved for a fraction of the cost of writing your own.

Define the wsdl to have a data structure that contains a collection of records.

btw, whether you use notbeans or not is utterly irrelevant.

Just use a commandline compiler and a text editor.

looks like Dani deleted "zuh koduz" :)

Rest assured, whatever you come up with will not be enough to get a passing score.

it's simple:
1) determine how much of a homework kiddo the person is (in your case, that's 100%)
2) deduct that percentage from 100 to give the maximum IQ of the person (in your case, 0).

you rez a 5 year old zombie for some useless stupidity?

correct. You're calling a method on your object instance before that instance has been fully initialised.
In the call to super you can pass only constructor arguments and static method calls, not instance members and methods.

he was talking about iterating over the structure and "clearing the buffer", so I assumed a simple loop iteration and bulk delete from the data structure, therefore no random access.

you're talking about random inserts and deletes, I'm talking about inserts and deletes only at the end of the list.
That's faster for single linked list as there's less to do (if you keep a pointer to the last element of course so you don't have to traverse the entire list to get to the last element) :)

so? Initialise the variable before using it.

there's a very nice Point2D class that might be just what you're looking for.

Your numbers aren't much exagerrated, except the nanosecond precision (it's more like microsecond) :)

Yes, we're talking about tracking massive amounts of subatomic particles moving extremely rapidly over a short distance accurately.

have you even read the 5 year old discussion above?

Trying to get into your current company's IT department might be a good move.
Maybe they'd be willing to have you spend say 2 days there, 3 days at your current position. That would enable you to gain skills while still being productive.

well, first you don't use JSP for the actual emailing.
You use servlets or EJB for that, the JSP are only the frontend (the screens) to display data and enable to user to interact with the system.

double linked list is slower for insert and delete and uses more memory.
It's only really preferable over a single linked list if you desire iteration in both directions.

The drawbacks are mainly in code maintainability.
Everyone expects to find 1 class per source file, including most IDEs.

See the filename, you know what class is contained in it and vice versa.
Want to change a class? Change that file and all other classes are not touched. Ideal for version control purposes.

Correct. NaN is defined mathematically to not be equal to itself.

JLS: Java Language Specification :)

disk space requirements already outpace CP requirements and have for years now.
Unless you're looking to process those petabytes of data in real time of course, but even CERN isn't that ambitious :)

how con i do this ???

By reading a few tutorials...

neither is "better", both have their place and will usually be employed together.

good luck. Sounds like a fun little project.
If you have specific questions rather than "do my work for me" do come back and ask for help.

First rule: don't do it unless you're using inner classes
Second rule: see first rule

Third rule: if you insist, read the JLS for what's allowed and what's not.

The main problem is the massive amount of data.
The same thing happens in some areas of physics where the amount of data generated in a single experiment can run into the petabytes.

Or you can block the server that generates the ads by adding it as an exclusion to your hosts file or blocking it in your firewall.
That will remove googleads from all websites :)

Just so you know the risks and won't be disappointed. Don't give up your current job yet ;)

The best thing you can probably do is learn the skills in your spare time while holding on to your current job.
When you feel comfortable, consider joining some open source project with a solid background (most are bad. and it can be very hard to figure out which is which) to gain practical experience.
That's the time to start looking for a job as well.

Were the economy and job market different (like it was in the late '90s for example) you could have gotten a junior job now and get on the job training.
In the current market that's no longer the case. There are droves of unemployed people with the right education and work experience who are a lot cheaper and less risky for companies to hire than you are, however talented you may be.

That's some extremely shady business practices your employer wants to use.
Automatically searching websites for semi-random phone numbers (and possibly other contact information) in order to blindly call people with marketing offers is no better than spambots searching usenet and forums for email addresses for their victim databases.

Sounds like what you really want is a single linked list.
That's fast for insert and iteration, slow for delete.

Storing them inside a jar that's loaded by the application is most convenient.
For maintenance reasons it's best this be a separate jar, so it can be delivered by different people once the project grows beyond the size of a single person and tasks get spread out (separate artists, coders, etc.).

Do preload at least the most common images on application startup for performance reasons.

Sounds like some Indian body shop, only interested in stuffing employees' resumees with tons and tons of buzzwords to make them seem competent.

Every recruiter claims to want talent, the "top 5 percentile" of candidates.
In reality, they prefer mediocrity as that's a lot cheaper and less likely to have high demands when it comes to what work to do and under what conditions.

I'll be brutally honest with you: you don't stand a chance.
Most companies won't hire anyone without experience when they're over say 25 years old. Too expensive.
And by the time you get your degree, you'll be 35+, at that age it's hard to get any job in IT at all.

no, we're not going to help you put trojan horses and other nasties on peoples' computers, which is the only real reason to want to put things on computers without the knowledge of the users.

Take pleasure in doing a good job, rather than in counting how many people appreciate the effort you put in.
Because you'll soon realise that hardly anyone appreciates your effort, least of all your customers.

Italian justice system has learned to not be corrupt. Had to deal with the Mafia for decades.
Maybe Google didn't realise that and tried to bribe a judge...

Can you share database for this bank ?

No. Banks typically use Oracle and other high end commercial databases. Sharing those is piracy.

Do your own homework, kiddo.
You can't understand things because you're too lazy to pay attention in class.

where's the urgency? I don't need something like that.

The best data structure to use depends on how you're going to use it.
Some have fast insertion but slow retrieval, others may have slow insert but fast retrieval.
Then again, retrieval speed will be different depending on whether you're doing sequential or random acccess of elements.

...If you haven't ever touched a Java program, shouldn't you be starting with HelloWorld.java?

Don't be silly! Everyone knows you should start straight with a big multitier enterprise application if you have no experience whatsoever!

and? Your question?

the bullies (if caught) would likely be handled unde juvenile law and sent home with a warning to never do it again if Italian law is anything like Dutch law.

Normally you'd use a combination of the two, depending on what is needed.
There is even a school of thought that advocates against the use of http sessions, says that everything should be either passed through the page, through cookies, or persisted in between requests (database for example).
While that's extreme, limiting what's stored in the session can be critical in high load applications as the session does eat up server memory.

use the name of the property, not the name of the getter.
So use RequestBySchedule, not getRequestBySchedule

can you plz tell me how to connect the sign up jsp page to access db???????????????
plz help me

Read reply #1

and anything that's easy AND popular won't pay much. After all, there's tons of people doing it and it's easy to learn so there's nothing special to it.

What pays well are things that are hard to do yet in demand, as there will be few practitioners at a high level of expertise.
