What does 'synchronized' mean?

Question

I have some questions regarding the usage and significance of the synchronized keyword.

• What is the significance of the synchronized

Answer 1

Think of it as a kind of turnstile like you might find at a football ground. There are parallel steams of people wanting to get in but at the turnstile they are 'synchronised'. Only one person at a time can get through. All those wanting to get through will do, but they may have to wait until they can go through.
