Hi everyone,
I know that variables declared inside a service method(local variables) are thread safe. Can some one give me an example and explain how are the variables thread safe.

Thank you,
Suni.

Simply put, there's just nobody else out there that has access to the variable once you've defined it locally.

Now, if you did something crazy like telling everybody else (threads) in your program about "o", then you would have a possible synchronization issue. But until that happens, local variables are nothing to worry about.

Simple Funda - each thread has their own copy of local variables, hence threadsafe
