Question about the task

Resolved

package com.codegym.task.task01.task0136;

/*
Even to the moon!

*/

public class Solution {
    public static void main(String[] args) {
        System.out.println(getWeight(888));
    }

    public static double getWeight(int weightEarth) {
        //write your code here



    }
}

"Amigo, did you know that lunar gravity is about 17% of gravity on Earth?"
"Nope."
"Neither did I. Now this information will be used a lot. To avoid having to manually calculate it each time, implement a getWeight(int) method that takes a person's body weight on Earth (in newtons), and returns the weight of that person on the moon (in newtons).
The method should return a double."

Consider this example:
The getWeight method is called with the argument 888.

Example output:
150.96

Requirements:

The getWeight(int) method must be public and static.
The getWeight method must return a double.
The getWeight method should not display anything.
The getWeight method should correctly convert the Earth weight in newtons to the lunar weight, and then return this value.

package com.codegym.task.task01.task0136; /* Even to the moon! */ public class Solution { public static void main(String[] args) { System.out.println(getWeight(888)); } public static double getWeight(int weightEarth) { //write your code here double weight = 40 * (17.0/100); return weight; } }

use this formula weight = earthWeight * 0.17;

public class Solution { public static void main(String[] args) { System.out.println(getWeight(888)); } public static double getWeight(int earthWeight) { // write your code here double lunarWeight; lunarWeight = earthWeight*0.17; return lunarWeight; } } // lunar gravity is about 17% of gravity on Earth so 17/100=0.17 we can write same thing as lunarWeight = earthWeight*(17/100);

solution

You should use the method argument weightEarth to calculate returned value.
