  • Fonts look horrible in any java application

    - by Eirik Berg
    All fonts in java applications look horrible. I have seen a few questions about this previously, but they are quite old now(11.04 was the most recent, but that didn't seem to be the same problem). For some reason java applications do not use the system font (Ubuntu 11), but rather some elongated font that doesn't seem to have any anti-aliasing. So

  • Should Swing knowledge be required from Java programmers?

    - by Anto
    Swing is an integral part of the Java API. It is also the most popular GUI framework for Java. I still wonder, should every Java programmer still know, or at least be pretty familiar with, Swing (possibly excluding web developers)? There are alternatives (e.g. SWT), but they are not very widely used (compared to Swing). What do you think about

  • What do you think was a poor design choice in Java

    - by Phobia
    Java has been one of the most (the most?) popular programming languages till this day, but this also brought controversy as well. A lot of people now like to bash Java simply because "it's slow", or simply because it's not language X, for example. My question isn't related to any of these arguments at all, I simply want to know what

  • Is Java's ElementCollection Considered a Bad Practice?

    - by SoulBeaver
    From my understanding, an ElementCollection has no primary key, is embedded with the class, and cannot be queried. This sounds pretty hefty, but it allows me the comfort of writing an enum class which also helps with internationalization (using the enum key for lookup in my ResourceBundle). Example: We have a user on a media site

  • Do you need to know Java before trying Scala

    - by gizgok
    I'm interested in learning Scala. I've been reading a lot about it, but a lot of people value it because it has an actor model which is better for concurrency, it handles xml in a much better way, solves the problem of first class functions. My question is do you need to know Java to understand/appreciate the way things

  • Can't copy from clipboard to any Java applet

    - by Thomas O
    The clipboard does not work with any Java applet on my install of Ubuntu 10.04. I am using the IcedTea plugin. I cannot copy/paste from Ubuntu to Java in either direction. However, IcedTea can copy to itself - that is, I can cut text from a Java applet and paste it into another part of that same applet. Other than

  • Analyzing Memory Usage: Java vs C++ Negligible?

    - by Anthony
    How does the memory usage of an integer object written in Java compare\contrast with the memory usage of a integer object written in C++? Is the difference negligible? No difference? A big difference? I'm guessing it's the same because an int is an int regardless of the language (?) The reason why I asked this is

  • How do I install Java?

    - by Jay
    I am using Ubuntu 11.04 Natty Narwhal. I recently installed openjdk-jre6 because one of the websites I use requires java for me to log in. Unfortunately, even after installing openjdk-jre6, I am not able to use the website. In place of 2 text boxes where I am supposed to enter my username and password, it simply

  • Constraints while designing the Java generics

    - by Andrea
    Java generics look quite different from those available in Scala, although both were designed by Martin Odersky. From my point of view, the design of generics in Java is worse, for instance: there is no possibility to specify variance one can get around the previous limitation by using wildcards, but this

  • Java Terms that are Plagued with Vaguery

    - by Adam Tannon
    What's the difference between a Java Process (what your OS sees) and a JVM? Are they one in the same or are they actually different? How are the JRE and JDK different (in purpose and file content), and which one contains the libraries for Java SE? What's the difference between the Java "Runtime"

  • Java is very slow on my laptop

    - by Ryan McClure
    I have 1.6.0_30 JRE on my 11.10 install. I have 3 GB of RAM and an Intel Core2 Duo CPU T6600 @ 2.20GHz × 2. Whenever I use my Java to play a game, the Java runs at about 4-5 FPS. When I used Windows, I found that I could get around 40 FPS. I'm not too terribly worried about this, but are there
