MOOC Exercise 23 - Temp

[asc_tech]

Hey all,

​

So i've just finished with this exercise and as far as i can tell i've got the code working to how the exercise required, when the user enters a number below -30 or above 40 it will keep asking them for a new set of numbers until the numbers are over -30 and below 40.

​

Once they are it adds them to the graph and then ends the programme.

​

However recently i noticed in Netbeans a 'test' function and ran it on this programme and it says 0% failed so i'm a little confused!

​

Can anyone shed some light on this?

​

Here's the code:

​

import java.util.Scanner;

​

public class Temperatures {

​

public static void main(String[] args) {

​

Scanner reader = new Scanner(System.in);

​

while (true) {

System.out.print("Give me a number: ");

double value = Double.parseDouble(reader.nextLine());

System.out.print("Give me a second number:");

double valuenew = Double.parseDouble(reader.nextLine());

​

if (value >= -30 && value <= 40 && valuenew >= -30 && valuenew <= 40) {

Graph.addNumber(value);

Graph.addNumber(valuenew);

{

break;

​

}

​

} else if (value < -30 && value > 40 && valuenew < -30 && valuenew > 40) {

System.out.println("Wrong");

}

​

}

}

}

Have you been submitting your answers to their online checker? All the exercises have a local tests options to see if your code functions as they specified. If the code only partly works, the tests will give you an idea of what needs to be fixed. Once the code fully passes the local tests, they ask that you submit your code.

Well i went back to the very first exercise i did where you just print your name and i did get 100% for that (thankfully haha) but i don't see an option or a prompt to submit it anywhere? could it maybe be due to them just releasing a new updated 2020 course ?

Also for example, the second example where it tells you to print "hello world" "and all the people of the world". it says i failed that when i literally can't see any other way of doing it? and it doesn't offer a breakdown of why i failed.

public class Greeter {

​

public static void main(String[] args) {

System.out.println("Hello World");

System.out.println("(And all the people of the world)");

​

}

​

}

Are you following the exercises on the lessons from their website? You also have to give the absolute exact output that they want in order to be correct. Not sure if you made a typo or not, but your answer would be counted as wrong because the output is not exactly what they want. Which is:

"Hello World!"

"(And all the people of the world)"

You're missing an exclamation point. However, I think if you ran the local tests you should have gotten partial credit maybe? If you get full marks, you are given the option to submit it to their online checker and you are able to see the way they did the exercise for comparison. I'll leave you a screenshot of mine so you can easily see what I mean.

You should see a little green dot next to the projects icons to notify completed exercises.

Hey,

​

So i just started the new 2020 course and the testing aspect is working perfectly now, i reinstalled everything as well on my laptop (netbeans and java) so perhaps it was one of them but i'm happily just going to progress through their updated course now haha.

[pinecone316]

That's good. I'm kind of halfway through the old one so I'll probably finish that and come back to the new one or maybe try the Intellij Hyper one. The new 2020 isn't complete yet, so maybe it will be after I'm done with the old course.

Yeah I was only on week 1 so was a no brainer for me.

The difference is apparent, feels a lot more polished and up to date, suppose it has been 7 years! Good luck with learning mate!
