Connect Samsung to laptop via USB cable. Laptop should mount the Samsung as one of your hard drives. You can then drag and drop files back and forth between the two.

To transfer files directly from a usb flash drive you will need a USB on the go adapter. If your tablet is rooted, StickMount will make the process much easier.

You can also use a computer to transfer the files, plug both the tablet and the flash drive into a computer and use windows to transfer them between the two devices.

Additionally you could use some sort of cloud storage to transfer them, attach the usb drive to the pc, and copy the photos to a service like Google drive or Dropbox, then simply download the files onto the tablet using that services app.

If your trying to view java with the default browser you will need to search the market for an AIO "all in one" Browser. This will let you view java.

Try connecting the Galaxy to your computer with the included USB cable. Then, select the notification (open the notification drawer by pulling down on the status bar) that says USB cable connected and follow the steps to mount your SD Card. At this point, the Tab should appear as a device/driver in Finder. If not, try connecting them to the same network and try something like On Air from the Market to connect over-the-air.
Since you are using an Android, you don't have to use anything like iTunes to transfer music and pictures. Simply copy them onto a folder on the SD card and then browse to them on the Tab using My Files and open them in whatever app you use. If you would prefer a proper syncing arrangement, try the free DoubleTwist app and corresponding Mac application to connect your device.

Even though Android is based on Java, you cannot just pop in a .jar file and play it. It needs to be in apk format, short for android package(i presume). You need to first transfer the file to your sd card and use a file manager to find it. then click + install. I suggest ASTRO (file manager)
