Java Optimizations

Question

I am wondering if there is any performance differences between

1. String s = someObject.toString(); System.out.println(s);

   and

2. System.out.pr

Answer 1

There is no* code critical enough that the difference between your two samples makes any difference at all. I encourage you to test this; run both a few million times, and record the time taken.

Pick the more readable and maintainable form.

* Exaggerating for effect. If you have code critical enough, you've studied it to learn this.
