Even to the moon!

To people saying "I got it on my second try": ok genius but people don't come here just to read how smart you are. This exercise is short, not easy though. It shouldn't be tagged as easy since there are some elements not explained previously. The key is "The method should return a double" So now, you know we need two elements. 1. double, which works like int adding the use of decimals. 2. return. We've seen these function before appearing in some exercise, probably you didn't know what is it for though. In this case, it works exactly as a System.out.println(). The last line of the example could be distracting, just avoid it. Let's focus on the exercise instructions. 1. "To avoid having to manually calculate it each time, implement a getWeight(int) method ..." ✔️This is already done in the second block: public static double getWeight(int earthWeight) { 2. "...returns the weight of that person on the moon (in newtons). The method should return a double.". So, create a double with a return. Note: You will need to use the 17% at the begining of the exercise here. double _____ = (numbers) * earthWeight; //very careful with capitals in earthWeight return _____; I didn't get it on my second try. I needed further more tries. Hope these steps help you.

I got it on my second try. Just had to add .0 to the 100 for the result to be type DOUBLE.

Okay, so I'm really getting the hang of the conversion program formula: Basically, all you need for ANY simple conversion program (lbs to kg...in to cm...feet to meters...) IS: A) One line of code to define a conversion formula (you only need one) Example: double VariableOne = 1/2*VariableTwo+37; B) State which variable to calculate for with the "return"

Ready

Am I the only one that's pretty far lost at this point?

When I googled the formula it gives a different value. Why do we calculate by the hint and not the actual formula for a precise result?

Hi guys, can some one help me understand why code on the left returns correct decimal value but code on the right does not ? Tnx

take double lunar weight and gravity....assign the value of gravity to 0.17..then lunarweight = gravity multiplied by earth weight.....then return the lunar weight........

So you already taught us how to use static variables, but if I try to use it in the task it thorws me an error, I think it would be better than magic numbers. I've tried to use this: public static final double LUNAR_GRAVITY = 0.17;

Please excuse my dear aunt sally
