Why doesn't it give me an output?

Question

I copied a this from an example code, but I can't manage to get an output.

The code:

int result = 0;
for (int i = 0; i < 5; i++) {
if (i == 3) {
result += 10;
} else {
result += i;
}
}
System.out.println(result);

Answer 1

String[] args is used to pass parameters usually in linux systems to the main function

and yes, i++ is executed before the check for i < 5, except for the first loop when it initialized and then checked

Answer 2

public class Program
{
public static void main(String[] args) {
int result = 0;
for (int i = 0; i < 5; i++) {
if (i == 3) {
result += 10;
} else {
result += i;
}
}
System.out.println(result);
}
}

it needs to be defined inside a main function

Answer 3

Thanks!

Why does it need to contain "String [] args"?

Also, does it execute the "i++" before it checks the "i < 5"?
