java - What's the difference between --i and i--?

Question

In some code i've seen a for loop with a --i as third parameters

for(int i=array.length; i<0; --i)

Maybe someone can explain me the difference with i-- ?

i guess it's something like the moment when i is decremented ?

Answer 1

例如，如果i = 5：

--i将 i 减 1，然后给您 i (4) 的值。

i--给出 i (5)的值，然后将其减 1。

两者都会在 for 循环中为您提供相同的结果。
