    Re: Why we use initialization block

    One last thing I forgot to say: one of the main useful purposes of having the initializer blocks is so that the same code to initialize can happen no matter which constructor is called, without...

    Re: FileArrayProvider?

    If you look at the first comment, the FileArrayProvider is the class he is creating as an example. Look at the package it exists in (com.acme), that should tell you right away that it is not...

    Re: Cannot find Symbol Error

    To add a little to Albert's, it is generally considered bad practice to name your variables and methods the same. It can cause confusion when reading the code (yes, I know: methods have the parens,...

    Re: Why we use initialization block

    The reason you would use initializers over the constructors is mainly useful for when you have final variables that may require programming logic to set them. Remember, a final variable MUST be set...

    Re: Insert data into mysql using jsf ?

    Sorry for getting back to you late on this, I have been away.

    Re: Insert data into mysql using jsf ?

    You have to create a bean class and reference it in the faces-config.xml. Create the bean class (nothing special unless you are using some tag library).

    Referencing it in the faces-config.xml is...

    Re: Insert data into mysql using jsf ?

    No. YOU provide the code, with error messages, and we will help you. Nobody is going to do your work for you. Do some reading up on how to do this, there are thousands of web sites that show...
  12. Re: question reagrding byte and integer size holder

    This is because the '+' operator is not overloaded to handle bytes. Instead it converts them to ints and performs the calculation. The possible loss of precision is because you now have an int...

    Please enlighten me and show me where it says in the rules for the discussion forum that I cannot "sleep for 2 or 3 days" and join a discussion? Oh, is this some sort of 'unspoken' rule from...
  14. Re: This exercise is not particularly difficult, but the concepts are new.Can u Solve

    Also, I would suggest that nobody click on the links he has provided. NONE of the Java2s links reroute you to anything like www.java2s.clanteam.com, all of them stay at www.java2s.com. There is no...

    So what you are saying, is that we should all learn to speak in broken English so that foreigners can understand better? Maybe we should use internet leet speak as well, or even Ebonics. :rolleyes:...

    Re: FileEncryption using PGP in Java

    PGP (Pretty Good Privacy) is not supported in the Java libraries. You have to download a third party library, like bouncy castle, and use that to encrypt the data with PGP.

    Opinions are fine, but insulting other people's choices is just uncalled for. Most of us can appreciate the fact that Java isn't the strongest language for desktop applications, but some people...

    Re: do scp from my java application

    This sounds like a UNIX/LINUX problem and not a Java one. Have you tried to run the exact command in the quotes at the command line?

    If that 'does' work, have you checked to ensure that the Java...

    I think you need to look at how you are processing the XML instead of how to increase the heap size. There are several different ways to process XML in Java, one of which is buffered so that you can...
