Java download to laptop - how do I launch/run etc

I recently downloaded Java software from the Oracle site to my laptop. I can see the files loaded under Program Files, but cannot see any desktop icons etc. Can anyone advise how I launch the software in order to write some code in the development environment, debug and run the code etc. Many thanks.

Thank you for the response. Can you advise which file to double click. Its not clear to me which one launches JDK. A large number of files were downloaded including many folders - bin, lib, etc. I cannot see any obvious file or icon that launches the software. I would appreciate any further advice. Thank you Gerard.Then you don't have an installer,that is just an unpacked JDK distribution. There is nothing left to click, you're done. And there is no "launching the JDK" - its a source development kit, not a program. Your first step is the java tutorial to get some of those assumptions out of your system.

Of course eventually you will want an IDE to manage projects with. You have a choice to make there; Eclipse and Netbeans are popular choices but there is also for example Oracle JDeveloper. But before you do all that: read and learn the truth.
EDIT:
one more thing; did you download the JDK or did you install the Java Runtime Environment (JRE) through for example java.com? I find it questionable that you never had to run an installer.

If you are syncing to the same computer that you always sync to, and have each of the items in itunes that you want synced then you shouldnt have an issue. The only way you would have an app come off your phone is if you uncheck that app from syncing in th apps location in itunes.

How can I Launch a Java application that I have written using an icon

I have just finished writing a Messaging system like Ms Outlook written completey in Java. To run my application , I would normaly type: java and then the class containing the main method eg java LogonFrame.
How can I launch my application by just clicking on an icon ?.
How can I also package and install this application the way most conventional application are packaged and installed. Do we have a sort of "java Installer" ?.
Thank you.

Just make a .bat file. Open notepad, type something like
@echo off
javaw -classpath %~d0%~p0 Package.MainClass %1
Now make a shortcut to this file. Rightclick the shortcut and select start in "minimized". Thats it...

After 2 years of not having a PC i now have a laptop... I downloaded iTunes. How can I retrieve my music library???

After 2 years of not having a PC i recently purchased and ASUS laptop and downloaded iTunes. How can I retrieve my music library?
I thought I backed it up on an external hard drive, but I can't import the files to my library...
I also still have my iPod with my full library on it, but if I sync it to my new iTunes, it will wipe the librarry.
Is there any way Apple can help me recover my music library?

If you downloaded it from the app store on your computer's iTunes then connect your iPhone to your computer and select it on the left-hand side of your computer's iTunes, and then use the Apps tab on the right-hand side of iTunes to select and sync that app to the phone.
If you downloaded it somewhere else then you won't be able to copy it to your phone - only iTunes apps work on iOS devices, PC and Mac software aren't compatible with them.

iTunes and Apple's devices work as an ecosystem. iTunes is designed to sync with Apple's products, not anyone else's. You'll need your songs in a format compatable with the Samsung phone and to use the software transfer program supplied/recommended. It is essentially not an Apple/iTunes problem. You may have better luck finding the information you need on Samsung's forums.

Welcome to the Apple Community.
You can only locate your device when it is logged into iCloud and 'Find My Phone' is enabled, additionally the device will need to be switched on and connected to a wifi or cellular network.
Unfortunately, you cannot activate iCloud or 'Find My Phone' remotely.
If the device is wiped by you or another, you may not be able to locate the device (although some have reported they can)

You'll need to explain better what you're trying to do.
I can't conceive what it would mean to merge applications on two different operating systems.
