The content doesn't matter. Sending a struct is not a problem. On the receiving end you just have to know what bytes were written onto the wire. It doesn't matter at all if those bytes where part of a struct data structure on the sending side. The "struct" doesn't get sent, but the bytes that make up the struct does. ============================================================================== TOPIC: [OT] Using hobby source code in your job ? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/a60dfe865a7807c4 ============================================================================== == 1 of 4 == Date: Mon, Dec 6 2004 10:23 pm From: Mark McIntyre On Mon, 06 Dec 2004 01:10:09 GMT, in comp.lang.c , "Andrew Koenig" <[EMAIL PROTECTED]> wrote: > >If your employer changed their mind about this policy, there wouldn't be >much you could do about it short of leaving.

A modern engineering company (such as Raytheon) tries very hard to keep it's engineering staff happy and "well fed" with intersting projects. If I create something "on my own time" that the company wants, they will truly make me a very generous offer for that product. In 20 years, I have never heard of the company "comandeering" a hobby project from an employee.

The documentation I have which discusses overloading methods within the same class says: "The overloading type of polymorphism occurs when you have the same method names with a class. You are allowed to do this as long as the methods have different numbers of parameters or different types of parameters. Having different return types does not count toward 'disambiguating' methods and won't help you if you need two methods that have the same names and parameters but return different types." In both of your cases, your methods have the SAME number AND type of parameters. In Case 1, the only difference between the two methods is the public/private and I don't see anything in the documentation that says the Java compiler uses that to distinguish between your first 'aMethod' and your second one. In Case 2, the return type is the only thing that distinguishes your first 'aMethod' and your second one but the documentation clearly states that the return type is not sufficient to distinguish between the two methods. As a result, the Java compiler is not going to let you create either case. You need to change your design so that you don't need to have two methods with exactly the same name and parameters. That shouldn't be too hard; just add a second parameter to one of the 'aMethod's and the compiler will stop complaining.

But I a C++ programer sees this code you would say: Thats not C++ thats Java. C++-Programer have another pholosophy (don't know how to write this in english). You will even be able to write a simple C++ program before you can read a difficult one. An writing a good and real C++ program would take a very lot of time if it's not impossible. The problem of you wouldn't be the HOW, this can be read by any book, but the WHY NOT. Java has a lot of good (and also a little bad) contructs in the library. And the STL (Thats the JDK of C++) is a awfull in my opinion. The other problem is the memory concept. But if you can handle C you will be able to learn that very fast. It's easier than in C but you can also use more hacks. cu Martin P.S. I came from Pascal over C over C++ to Java. I wrote my diploma about C++ and Java, so I think I can write a little about those two languages. == 2 of 3 == Date: Mon, Dec 6 2004 5:05 pm From: Sudsy Rhino wrote: <snip> > I'd be very curious to know how long it took people here who were fluent in > Java to get fairly fluent in C++ if they started with approximately the same > skills I have today.

I've been using Java constantly for about a year and a half. I feel that I could pass the SCJP at any time without studying in advance (an opinion supported by some coworkers who have taken the exam). That said, a couple months ago I picked up a good sized C++ book and read it through in a week (with some hands-on interspersed throughout, of course). After that I felt comfortable reading some simple and not so simple C and C++ source code and writing my own simple little things. If you want an eyeful, download the Quake 2 source code (C only, I believe). If you can even begin to untangle that I'd say you're doing fairly well.

We used coding tests ("Programmer Aptitude Test") at IBM many years ago. It was actually pretty simple and tested logical thinking. However, it ran into legal problems. A test used to select or reject candidates must be shown to be predictive of the work to be done; i.e. does the outcome of the test actually reflect the ability of the candidate to do the actual work? Unless there is some formal proof, the test can be deemed predujicial and restrictive. The burden of proof falls on the employer to show that those persons who do well on the test actually do well at the job. I have found that chatting with a candidate, his hobbies, and previous experience was more useful in evaluating several things, only one of which was how he would do with the work. Work assignments can be tailored, monitored, mentored, and trained for. More interesting is what personality traits I could detect -- would this person "fit in," be interested in solving puzzles, have the temperment to put up with frustration? Granted, it is hard to evaluate with one sitting; thus, we had several persons do interviews, and have call-backs to explore deeper. I still think a person who can solve puzzles and enjoy them can become a good programmer. Anyway, most job positions are so nebulously defined that many levels of skill and experience can fit into them if need be. I always laugh at the "requirements" the HR department puts on openings. Their job is to eliminate candidates from the mix, but they cover the ground so thoroughly that there is never anyone who could fit their requirements. They seem to think an entry level programmer should know C++, Java, Enterprise Editions, XML, UML, SQL Server, Oracle, SAP, and sometimes COBOL and assembly language. Go figure. Here's an example I just pulled from Monster: Requirements for a Java programmer: - 2 years experience working with Documentum products (version 5 preferred). - Knowledge of Documentum APIs, DFCs, DQL, WDK, Application Builder/ Developer Studio, Workflows, and Lifecycles. - Programming experience in Java, JSP, XML, XSL and COM. - Web development skills with knowledge of databases.

How does it hinder refactoring? Search-and-replace the old class name for the new class name in one source file and it's done. Not a problem.

Would you by chance know to set it up to send logging info to a file? I have this class as part of a web app, package app.model; //import java.util.*; import org.apache.log4j.Logger; import org.apache.log4j.BasicConfigurator; public class Log4j { static Logger logger = Logger.getLogger(Log4j.class); // debug, info, warn, error, fatal public String logMessage(String sText, String level) { BasicConfigurator.configure(); if (level.equals("debug")) { logger.debug(sText); } if (level.equals("info")) { logger.info(sText); } return("yes") ; } } ...and I modified the original LogonAction.java file with this(instead of getDegug()) String sText ="LogonAction: User " + username + " logged on in session " + session.getId(); Log4j log = new Log4j(); log.logMessage(sText, "debug"); This code compiles and runs but I can't figure out where the output is going. This is the log4j.properties file, which is located in the same directory as the class file. log4j.rootCategory=DEBUG, dest1 log4j.appender.dest1=org.apache.log4j.FileAppender #log4j.appender.dest1.layout=org.apache.log4j.PatternLayout # Appender dest1 writes to the file "test" in user's home. log4j.appender.dest1.File=${CATALINA_HOME}/webapps/EP/WEB-INF/classes/app/log # Truncate 'test' if it aleady exists. log4j.appender.dest1.Append=false Thanks, Peter == 2 of 2 == Date: Mon, Dec 6 2004 7:39 pm From: "Ryan Stewart" "zpetero" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] >I got that and have since set up and tested Log4j, > > The tricky part is getting it to output to the file I want. > > Would you by chance know to set it up to send logging info to a file?

One thing I do notice is the first line should be "log4j.rootLogger=..." and not "rootCategory". Did someone do a global find and replace? Those are very dangerous. The ".File" tells it what file to write to, which should be in the specified directory within your Tomcat installation directory (assuming it is expanded properly; I don't think I've tried EL in here). Finally, I don't recognize that last line with the ".Append". ============================================================================== TOPIC: How to initialize a big (String-)Array fast? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/7a849e4e56de0eae ============================================================================== == 1 of 1 == Date: Mon, Dec 6 2004 5:46 pm From: "Tim" I was replying to Patrick's original post so maybe I should have bypassed Michael's response. Didn't yet see the "Threads" option in Googles' new beta DejaNews interface. Doesn't Java run on some 64-bit processors? I too was surprised 1.5 did not integrate 64-bit addressing. OS's incorporated this in the mid-90's so Java not having it is questionable. As always, when the processor cannot access available RAM then the "OS magic" for accessing secondary memory (disk, swap, pagefile) comes to bear. In this case, create a class that implements Collection but serves Strings. Back it with File or RandomAccessFile. You can even amortize the initialization by initializing on access and make it "faster" in total time used because you will not allocate Strings unless they are used. Of course, the simple fix is to allocate an array of array of Strings and make accessors. John, about 64MB memory-mapped blocks, I guess this is like on a 64MB RAM machines? For this RandomAccessFile, at least with 1.4.1_05, barfs if you try to access more than the given amount of RAM. TIJ refers to this limit correctly as length(). http://www.eastons.org/tij/TIJ314.htm#Index1408. This memory is not GC'ed either AFAICT! Anybody know if the filename given can be used by other code (non-Java) to access the same RAM? That's one thing cool I remember about Winders createFile.
