The method neither relies on external state nor maintains state at all. Hence, it's considered to be thread-safe and can be safely called by multiple threads at the same time.

  • How to make a method thread-safe in Java?

    If a method doesn't need to use any of the instance variables or the 'this' reference, you might as well make it static, for greater flexibility of use. But it doesn't really have much to do with being thread-safe. I always understood that a static method means it's a class method and that all threads using this method use the 'same' copy.
