TemperatureConverter.javaSubmitted by Sam Patel

1public class TemperatureConverter {
2    public static void main(String[] args) {
3        int f = 98;
4        int c = (f - 32) * 5 / 9;
5        System.out.println(f + "F is " + c + "C");
6    }
7}

Sage's draft for line 4

Both sides of the division are ints, so 98°F comes out as 36 instead of 36.7. Divide by 9.0 to keep the decimal.

Your note: So close, Sam. It's a one-character fix.

Sam can't see any of this until you release it.

Everything else a CS class runs on, in the same place.

Java that runs in the browser

Students write in a real code editor and press Run. Their code compiles and runs in an isolated sandbox, so they see output and errors before they submit.

double f = 98.6;
double c = (f - 32) * 5.0 / 9;
System.out.printf("%.1f°C%n", c);

Every section on one calendar

Give each class its meeting times and a color. Class meetings, due dates and one-on-one sessions show up on a shared calendar for you and your students.

Quizzes that grade themselves

Multiple choice and true/false are scored the moment a student submits. Short answers come to you, with a suggested score from Sage when you want one.

A place for the questions students hesitate to ask

Each course has a forum where students can post anonymously to classmates, plus private threads that go straight to you.

Why does 7 / 2 give 3?

I expected 3.5. Is my computer broken?

Alex Rivera, teacher

When both numbers are ints, Java drops the remainder. Try 7 / 2.0.
