java - What does the ++counter mean? -

this question has answer here:

i don't consider myself bad @ programming, there's been troubling me since past few days.

int counter = 3; ++counter;

is following code above same counter++;.

it similar, not same.

in expression doesn't matter, if had more complicated, system.out.println(counter++), make big difference.

for example: int counter = 3; system.out.println(counter++)

this print 3, increment counter 4.

however, if do

int counter = 3; system.out.println(++counter)

it print 4 because increments prior giving value parameter print function.

it's question of when increment performed, prefix performs before other operations, postfix performs after. have different precedences.
