Write a program that asks the user to enter an object's mass, then calls a / / function to return the object's weigh in newtown. If the object weighs / / more than 500 newtons, the function also displays a message indicating that / / it is too heavy. If the object weighs less than 100 newtons, the function / / also displays a message indicating that it is too light.

import java. util. Scanner;

public class num8 {

public static void main (String[] args) {

Scanner in = new Scanner (System. in);

System. out. println ("Enter the mass");

double mass = in. nextDouble ();

double weight = calWeight (mass);

System. out. println ("The weigth is "+weight);

}

static double calWeight (double mass) {

double weight = mass*9.80665; / / assume a = accelation due to gravity = 9.80665N

if (weight>500) {

System. out. println ("Too Heavy");

}

else if (weight<100) {

System. out. println ("Too Light");

}

return weight;

}

}

Explanation:

Using Java programming language The main method is created to request and store a variable, mass in kilogram. The main method call calWeight () and passes the value for mass A method calWeight () is created that calculates the weight in newtons (mass * 9.8). The method checks if the weight is greater than 500 (prints too heavy) if less than 100 (prints to light) Returns the weight
