for loop format

Ok so everybody knows the standard for loop format of:

for (initialization; termination; increment)

but what does it mean when you add a 4th expression to the mix?

this is from the Java Tutorial 4th Edition pg. 250

for (int i = 0; n = elements.length; i < n; i++)

Can somebody explain this please?

Good luck getting that to compile.

Perhaps you're thinking of something like this? for (int ix = 0, jx = 10; ix < 100; ix++, jx++)

oh wait - this just means initialize 2 things before starting the loop, right? I get it now.

This is the initialization:int ix = 0, jx = 10int ix is initialized to 0 and int jx is initialized to 10.
