How to force reinstall Java

A fue weeks ago I must have somehow deleted java folder from the utilities and now cant get it back. Ive researched this heaps but im getting nowhere. Does anyone no how to reinstall java (and you cant use an update). And there is no native install.
Im running 10.6.6 (latest)
All help would be great
Thanks

Yes indeed and subsequently re-applying Java for Mac OS X 10.6 Update 3 would be a good idea, since it made changes to the Java Preferences application, moving it to v13.3

How can I reinstall JAVA on Mountain Lion?

The last Java Update screwed up Java on Mountain Lion. Thanks a lot, Apple. This is where blinking/flashing images etc etc start, and it also affects the three-finger word-look-up gesture. I compared my mac running Facebook in Safari with one in an AppleStore and the one in the shop renders the Java stuff flawlessly -- no blinking or flashing graphics, and the three-finger tap gesture works perfectly. Both macs were running the same version of Java, OS X and Safari.
If I turn off Javascript and Java (in Safari) I don't get the flashing images and three-finger-tap works.
So my question is (after reading similar threads of the same topic): IS there any one-click solution to this -- can I reinstall Java, or do I have to re-install Mountain Lion... JUST to get Java working again??!?
And per the above.. why ISN'T there a standalone Java re-installer for OS X? How difficult could it be??

I just found the solution, thanks to the "MORE LIKE THIS" links:

That's where you can download the standalone installer!! I did it, ran it, and it works. Solved all the problems I've been having.
Thing is.... why is it hidden???

Have you tried installing Java 5.0?

Having reinstalled java. Iahve tools which I do not know how to use.

I have Windows XP, and have reinstalled Java as the previous version had wiped clean. At present have a subfolder of program files called java which has a sub folder called jdk1.8.0_18, but I do not how to use these tools to compile and run programs. Previously I had something which could the mouse. How am I to use these tools?

I was abel compile and run a file, but it was a little more complex than suggested and I would lile to know to do with a a mouse,At this point, if you actually want to learn java, then using the command prompt is your best bet.
I have no idea what "do with a a mouse" means. Was there a specific tool you were using before? I'm sure you can set which compiler it uses somehow. Or you could just use an IDE. In either case, google is your friend. But you should be using the command prompt until you're more familiar with what's going on behind the scenes.

Bad juju not having a bootable backup that you can revert back to when you run into these kinds of issues. Get a bootable, external HD, and make a bootable backup/clone before updating/upgrading and ensure that it's bootable and works like the original. See these for details:

Back to your issue. Boot with the Leopard install disk, select your language, select Disk Utility from the Utilities menu, and repair the disk and permissions. Report back.

I cannot reinstall java after uninstalling due to issues with it.

Well, over the past few days, I have been unable to use anything to do with java. After asking around a bit, I was told I should reinstall java. So, I removed anything to do with Java, and then went to system update to re-download it.
Now, the funny bit. (maybe)
After removing it, I checked for updates via system update, and, lo and behold, it wasn't listed as an update.
I am wondering, how do I re-download it, and without the issues it has been having?
I run a 10.6.8, with a 2 GHz intel core 2 duo.
Thanks.

Klaus; When I tried that, it said seomthing about it not being recognized >.>
I'll try a re-install if things get desprate, I live somewhat rurally, and got some tech savvy people to install, so I'de have to take it in >.>
thanks guys

While installing Lion my Bluetooth module disappeared. How can I reinstall it?

While installing Lion my Bluetooth module disappeared. How can I reinstall it?

You ought to get a dialog asking to install the first time you run an app that needs it
Details here:
http://www.macworld.com/article/1167855/installing_mountain_lion_what_you_need_t o_know.html
The relevant bit is this:
Note that the first time you try to load a webpage or run an app that requires Java, Mountain Lion will prompt you to download and install the Java runtime, even if you upgraded from Snow Leopard or Lion and you’d previously installed Java. This is normal—you shouldn’t worry that installing Mountain Lion somehow “lost” any of your data or apps.
Or you can go to the Apple Downloads page and search for Java

Application files are corrupted. How do I reinstall application files?

I own the macbook Pro. My application files are corrupted. How do I reinstall them?

"Any more ideas?"
The point of my reply was for you to apply the 10.3.9 Combo Update over your installation. Repairing Permissions is always a good idea before and after any update or upgrade. Did you try this and still having Java problems/errors?
This will not harm anything to apply the Combo update over your OS.
You did not post which version of 10.3 you are using but you may wish to check to see if this Apple Knowledge Base article applies to your situation:

What if I need to reinstall Java?

I made the mistake of trusting a Java applet and the site downloaded a .jar which apparently corrupted the " javaws cache". I went into the java cache and deleted the items that were installed and no longer get the error but I am concerned that i don't have a complete java...

How do I uninstall java?

Very simple. How do I uninstall java?
I used it once for a GoToMeeting session, but I'm quite happy not having the jvm/javac/java binaries kicking around. Short of `find | egrep -iE '(java|jvm|javac)'` and surgically removing individual files, is there an uninstaller for java?
I lump java in to the same category of battery-wasting malware as Flash and I'm quite happy to exist without it. Help?

Unfortunately there is no direct or easy way to uninstall Java, so once installed the only way to remove it and all of its components completely is to reinstall OS X; however, you can remove the Java virtual machine...
