Variables in Threaded Static Methods

[BillyKrow]

I have a static method I'm using as a utility in a Servrlet class. Since the servlet class will be threaded I'm worried about data integrity. The question is really simple. If I declare an array within a static method like this:

someObject [] arrayOfSomeOjbect = method ();

If method () returns an array of someObject am I actually allocating memory for a new array each time or do I risk the threat of the threads overwriting the variable?
I understand with new instances of objects I risk no threat but wasn't sure if this was the same case.

Strictly speaking the answer as you phrased the question is no. method returns a reference to an array object. So…

 someObject [] arrayOfSomeOjbect = method ();

arrayOfSomeObject catches the returned reference no allocation occurs at that time.

>> do I risk the threat of the threads overwriting the

That depends on what method() returns you. If "method" is returning a referece to a single instance of an array then yes. If on the other hand "method" is allocating a new array and returning the reference to that new array then the answer is no.
