Java 8 gives error message with Windows XP.  Can it still be used?  What are the latest issues? Windows xp is no longer supported but will Java 8 still work on Windows XP computers since so many people still have windows xp?

I just went to install Java 8 on my ancient laptop that runs Windows XP SP3.  Java pops up a message:     Java 8 requires a newer version of Windows. You may continue with the installation, but for Java to work as specified we recommend upgrading your computer's operating system.   Will Java fail to work properly on Windows XP? Or is this just Oracle trying to be secure?

I don't know which version of Minecraft I have. I have regular Minecraft, not Java or anything else and I just don't know the version I have.

How can I find out whether my install of Windows (specifically XP and Vista) is either 32 or 64 bit?  Additionally, how can I find out if my hardware will support a 64-bit operating system?

What is reflection, and why is it useful?  I'm particularly interested in Java, but I assume the principles are the same in any language.

How can I have a different input method for each app window on windows 8. When I change input language to ENG all app window also uses this method and I don't want that. Like windows 7 that has a different input method for this purpose. thanks

Chrome refused to run a java app unless i upgraded to .45, which I did my dling the installer from oracle.  Java 7 u45.  Installer said it worked.  Chrome still won't start java.    $ which java /usr/bin/java  $ java -version java version "1.7.0_06" Java(TM) SE Runtime Environment (build 1.7.0_06-b24) Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode) ~/private/WDI/git🍔     I may be easily fooled, but that doesn't say "45" anywhere.  (Yes, "06", and "24" and "23.2-b09", but nary a 45.  Such numbers!)  Anybody know if this is u45, or where the installer placed it?  UPDATE: there is a Java System Preference Panel that says "Your system has the recommended version of Java: Java 7 Update 45."  Still, Chrome doesn't appear to see it.

I keep getting, since several days, "System program problem detected" error message:    I always clicked on Report problem button but nothing happens.  I also run update and upgrade everyday.  What causes this ? How to get rid of it ?

would report a violation for:  ArrayList&lt;Object&gt; list = new ArrayList&lt;Object&gt;();   The violation was "Avoid using implementation types like 'ArrayList'; use the interface instead".  The following line would correct the violation:  List&lt;Object&gt; list = new ArrayList&lt;Object&gt;();   Why should the latter with List be used instead of ArrayList?

Okay, what is it, and why does it occur on Win2003 server, but not on WinXP.  It doesn't seem to affect my application at all, but I get this error message when I close the application.  And it's annoying (as errors messages should be).  I am using pyOpenGl and wxPython to do the graphics stuff.  Unfortunately, I'm a C# programmer that has taken over this Python app, and I had to learn Python to do it.  I can supply code and version numbers etc, but I'm still learning the technical stuff, so any help would be appreciated.  Python 2.5, wxPython and pyOpenGL

Microsoft stopped updating Windows XP and the media warns us of security leaks. I actually just read that continuing to use Windows XP is "extremely" dangerous. Why exactly is this such a danger? I would believe that by now XP should be pretty safe to use after years of updates.   Are there particular things XP users have to look out for and perhaps take counter measures against?  I would also believe that all the interesting places for hackers will update to Windows 7/8 and serious threats will not be created anymore in the future, at least not specifically aimed at Windows XP.

How can I detect when an Exception has been thrown anywhere in my application?  I'm try to auto-magically send myself an email whenever an exception is thrown anywhere in my Java Desktop Application.  I figure this way I can be more proactive.  I know I could just explicitly log and notify myself whenever an exception occurs, but I'd have to do it everywhere and I might(more likely will) miss a couple.  Any suggestions?

I just want to clarify one thing. This is not a question on which one is better, that part I leave to someone else to discuss. I don't care about it. I've been asked this question on my job interview and I thought it might be useful to learn a bit more.  These are the ones I could come up with:   Java is "platform independent". Well nowadays you could say there is the  project so C# could be considered too but I believe it is a bit exaggerating. Why? Well, when a new release of Java is done it is simultaneously available on all platforms it supports, on the other hand how many features of C# 3.0 are still missing in the Mono implementation? Or is it really  vs.  that we should compare here? Java doesn't support events and delegates. As far as I know. In Java all methods are virtual Development tools: I believe there isn't such a tool yet as Visual Studio. Especially if you've worked with team editions you'll know what I mean.   Please add others you think are relevant.  Update: Just popped up my mind, Java doesn't have something like custom attributes on classes, methods etc. Or does it?

Support of Windows XP . There is a lot of fuss and fear around this and many  on what you should do but I haven't found a clear explanation: What does the end of support actually mean?   There won't be any new updates. This is the only thing which is clear. Will we be able to get the old updates?  weakly suggests that yes, but I haven't found any more confirmation of that. Will we be able to install Windows XP on new machines? There was some procedure of confirming the key over the network (registering windows), so will this work as before? Are there any other direct changes for users of Windows XP?     Note: I am not asking on security consequences of the above, and have my own opinion on updates of this product, so please be so kind and skip the big warnings and disclaimers how it's impossible to use XP without updates. There have been a lot of scaring people and no actual explanation of what actually is going on - this question is meant to fill in the gap.

Possible Duplicate:          I'd like to create a Windows .exe for a Java program. Previously, I've used JEXECreator for this, but it's not entirely satisfactory because:   The executable sometimes works on the machine on which it was created but not on others. The program is commercial; if you use the trial version, it adds a nag screen to your application.   I don't need the generated .exe to work if Java is not installed on the target machine (in fact, I think this is impossible).  Any recommendations?

I do not own Minecraft outside my PS4, I know I can't play either Windows 10 or Java with that purchase. However, my primary computer is Linux and only supports the Java edition, and its past the deadline to get a redeem code for Windows 10 edition if I purchase the Java Edition.    Can I purchase the Windows 10 edition and use that purchase to login and play on the Java edition?
