Reviving a vehicle that has been idle for a long time.

I left my car in a driveway for a year. I read that I shouldn't try to jump it because the battery might explode. Is that true?

What should I do to get my car back and running?

It is a 95 honda accord and was in great condition before I left it.

Not that it would explode, but a discharged battery will take a lot of driving to recharge to be able to start the car next time. So it would be best if you take out the battery, and connect it to a charger plugged into a mains outlet. The charger should have a maximum current in Amperes of about 1/10 of the Ah capacity of the battery (so for a 45Ah battery a 4A charger should be fine). Lower current is OK. Keep it plugged in charging for about 24 hours (more if the charger has lower current then 1/10 of Ah capacity of the battery).

If you have a voltmeter, you can measure the voltage on the battery terminals while charging - charge it until it is at least 14.4V, and then 6 hours more. Put the battery back into the car - it should start fine.
