Now if there were a number with positive significance between these two...


A good example is 1 us$ = 6.66 chinese yuan.
"6.66" in chinese means that everything goes well, forever.

I agree with all you guys. After went through the Sierra-Bates' book twice, I took the exercise questions in each chapter and got around 80%. I also picked 3 of the Dan's, but only scored about 35%. In addition, I completed the Marcus's with 46/60.
BTW, does the SCJP exam focus on the concepts more than the details, for example the APIs?

Congrats!
You must be an extremly excellent coder and be detail-oriented. Without rigorous preparation, it is not easy to pass with 95% even for an experienced programmer.

Thanks for help.
Looks like using the "split" method is a way to go. Just found this was mentioned in Java 1.4.2 documention.

"StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead."

I heard that the regular expression is a good thing.

I have a string with is retrieved from database.
The string looks like "1,2,15,23,232", which is a type of SET in the database.
In the Java program, I need to obtain each separate index from the string "1,2,15,23,232". Can any one let me know how to do that EFFICIENTLY?
Thanks a lot.

While preparing for the SCJP exam, I come across the statement in various situations:
"Be careful not every JVM enforces the rule... "
What does that implys? Why people make such difference between the different versions of JVM?
Any ideas? Thanks.
Not only IT, every industry will get influenced by Globalization.
Both China and India have a large pool of well-educated labors. While we have a unemployment rate of 6.4%, the figure of either China or India is 20+%.

C is just so difficult not many students like it.


C language itself isn't more difficult than Java itself. People tend to use C, not Java, to solve more technically challenge problems.

Simply speaking, when you run http over SSL, http becomes Https. Implementation of SSL/Https would be the job of administrator, since it is not the security of application level.

I am writing a simple channel for my company's portal. Basicly the channel get job advertising from a companys's internal server via http call. Since the channel will get very high traffic, I hope it as thin as possible.
Background:
When user clicks the "serach" button, the channel will eat in 5-10 job feeds (as separate XML stream). A single feed can contain no job or 100 jobs. The feeds have to be assembled for transformation.
Solutions:
1. Concantenate the feeds using StringBuffer().
2. Parse the feeds and generate a now DOM.
Which is better considering the performance? Any other solutions?
Thanks

Why?
You have BSc (3 year) degree in CS and you and the MSc in CS. Why does a four year bachelor still counts?
You have 3 year WORKING experience in all major fields in J2EE. But you wage is only US$150 per month? Even if you are inh India, still does not make sense to me.
You may go for SAP. But the training would be extremely expensive, at least here in US.
cheers,

Of course, as a J2EE developer I do not want EJB goes away and would like to see its continuing progress.
However, if you compare the 2 J2EE tutorials, the 1.3 and the newer 1.4, you may find that Sun still keeps all the old chapters (Servlets, JSA, security,...) except those on EJBs, stressed significantly the web services. What does that mean to newcomers? Looks to me what suggested by Sun is obviuos. Poor Sun.
As for the IBM, the sell point of their new WebSphere 5 series is the web services. They also want people to use their WS 5 express, which has no support for EJB.
Since I got 2 vouchers (another is the IBM 484 J2EE 1.3), I will take the tests anyway.
I got the voucher as well. But please take look at the Sun's J2EE 1.4 tutorial
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
Among the total 21 chapters, only the 17th is specifically talking about EJB. Even that is from a perspective of the WebService. Actually the tutorial is all for web_service stuffs.
I am wondering the future of the EJB? Why do we spend time on what seems to be disappearing?
Please clarify, since my work touches very little EJB, but is heavily on XML/Servlets/SOAP.
