java - for() statement instructions order -



java - for() statement instructions order -

i create sure understand for() loop in java. java tutorials:

for (initialization; termination; increment) { statement(s) }

docs says: "the increment look invoked after each iteration through loop"

int x = 10; for(int y=2;x!=1;x++){ system.out.print(x); x=x-y; //actual x++ operation? } //prints 10 9 8 7 6 5 4 3 2

is x incremented after system.out , x=x-y?

yes. x incremented after finish operation run. if things x, should increment regardless.. in each step subtract 1 x because start subtracting two, add together 1 increment.
