My SD Card slot is corrupted.
I was under the impression BRCM was Broadcom Wireless hardware?
LaCie XtremKey is a USB flash drive.
What do they have to do with printers. Something queer is going on with this printer business. I don't own a printer. I haven't needed to print a page in years. But TM crashes prior to completing a backup. The logs don't say much but they talk about the xxx/cups folders being fiddled with (as the reason for the failure of Time Machine to...function).

When i run the program if i input something that triggers the exception, it infinitely loops through the question and the catch method block outputs, weirdest thing of all is that i can't even input again after the exception is thrown, but with nextLine() it avoids that, but i still dont understand why do i have to use nextLine().Exactly what I said.
You enter "A". The exception is thrown. The "A" is not consumed. It calls nextInt on "A" again... and again... and again...
If you do nextLine, the "A" and the newline are consumed.
Even on good input, I don't think nextInt consumes the EOL.
