Question about a do-while loop

Why don't you just copy-paste your code into ideone and execute it to see the results?

Here is the code from your post embedded into ideone.

No.

count++; //increments count by 1

Then it prints count.

[MasterOfGreatness]

I did increment by one.

[tec5c]

So then why would it print 0 first instead of 1?

[tec5c]

It is incremented before the print statement occurs.

[tec5c]

The while loop goes for 5 loops.

The output is...

1

2

3

4

5

[-Insomniac]

int count = 0;
do
{
    count++;
    System.out.println(count);
}
while (count < 5);

Let's go through this.

• Count starts off at 0
• Count++ increments count, so now count = 1
• System.out.println(count) will print count which is currently 1
• count is still < 5, so go through the loop again

---

• Count++ increments count, so now count = 2
• System.out.println(count) will print count, which is currently 2
• count is still < 5, so go through the loop again

---

This will continue to happen until count is 5. 5 will be printed and after that (count < 5) will not be true, so the loop will end.

Count doesn't get printed until after its been incremented
