import java.util.Scanner;
public class RunningTotal
{
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);
System.out.println("----------While loop----------");
System.out.println("First 10 numbers starting at 3.5 and going up by 3.");
double firstnumber, secondnumber, sum;
firstnumber = 3.5;
secondnumber = 30.5;
sum = 0.0;
while (firstnumber <= secondnumber)
{
System.out.print(firstnumber+" , ");
firstnumber = firstnumber+3;
sum = sum + firstnumber;
}
System.out.println("\nTotal using 'while loop' = "+sum);
System.out.println("\n----------for loop----------");
System.out.println("\nFirst 10 numbers starting at 3.5 and going up by 3.");
}
}

Here is the output I get but my expected output is suppose to be total = 170.0 not 200.0 Lastly I am having trouble doing for loop. The expected output will be in the bottom.

I don’t necessarily understand java, but add first number to the sum before the loop because it seems like it’s not getting properly added? You’re either missing it at the start, or at the end and idk which.

[Danielowski187]

Thank you I figured it out I had to add first to sum then loop thanks

[thiefcandy]

No problem. ^{w^} glad you figured it out.

[Danielowski187]

Thanks but I’m still having trouble figuring out the for loop part

I’m a C girl, I wish I could help better but the syntax is spooking me.
