Difference between pre increment and post increment in for loop

Question

Is there is any difference between following two for loops

For(int i =0;i<5;i++)
System.out.println(i);
AND
For(int i=0;i<5;++i)
System.out.println(i);

If any state with description

Answer 1

Muhammad Khairul Amirin Bin Yaacob both will have 01234
output
In loop post - pre increment will not make any difference

Answer 3

1. for (int i=0;i<5;i++)
output: 01234

2 for (int i=0;i<5;++i)
output: 12345??

Answer 4

Gordie nice post. Thank you.

Answer 5

Muhammad Khairul Amirin Bin Yaacob That's wrong. The incremention isn't used directly and therefore it doesn't matter if you use ++i or i++. Pre- and postincrement only differs when you pass it to something while incrementing it.

However: it's better to use pre increment, because post increment is more costly.
Pre increment directly returns the incremented value, but post increments need to copy the value in a temporary variable, increment the original and then returns the previous made copy.

Answer 6

Question: how would your answer apply to overloaded increment operators for an object? In case the answer is no: would it be bad practice to even implement post increment in a costly class?

Answer 7

pre increment increase the number before and then proceed but post increment proceed the value before and then increase
