How can I rewrite the following while loop using a for loop?

[gt11990]

int count=0, sum=0;
while (count<5)
{

sum = sum + count;
System.out.println(sum);
count++;

}

thanks :)

int count=0, sum=0;
while (count<5)
{

sum = sum + count;
System.out.println(sum);
count++;

}

thanks :)

		int count=0, sum=0;
		for (int i=0; i < 5; i++) {
			sum += i;
		}

can you explain (if possible) how you converted it into the for loop am really confused and new to this

thanks

easy, take the syntax of the for-loop

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

and then replace the initialization, termination and increment according to your needs. your count was initialized with 0 so then initialization is 0, your while loop contain count < 5 so the termination is also i < 5 and the increment is 1 because your increment was count++

Ohh i see thank you very much, this java is so complicated :)

		int count=0, sum=0;
		for (int i=0; i < 5; i++) {
			sum += i;
		}

That's close, and your explanation is correct, but I think this is a more accurate translation:

        for (int count = 0, sum = 0; count < 5; count++) {
                sum += count;
                System.out.println(sum);
        }

Actually, that is probably what the instructor wants, but it's not really an accurate translation, because the count and sum variables will not survive the loop, as they do in the while case. This code works the same as the while loop, but is ugly:

        int count, sum = 0;
        for (count = 0; count < 5; count++) {
                sum += count;
                System.out.println(sum);
        }
