From the Book "Core Java for the Impatient", Chapter "increment and decrement operators"
String arg = args[n++];
sets arg to args[n], and then increments n. This made sense thirty years ago when compilers didn’t do a good job optimizing code. Nowadays, there is no performance drawback in using two separate statements, and many programmers find the explicit form easier to read.
I thought such usage of increment and decrement operators was only used in order to write less code, but according to this quote it wasn't so in the past.
What was the performance benefit of writing statements such as String arg = args[n++]
?
