I suspect it would be something like
public class Einstein {
private double mass=0, energy=0;
public class Relativity implements IEquation {
Relativity(double mass) {
set_mass(mass);
}
public double getEnergy() {return energy;}
public double setEnergy(double newEnergy) {
energy = newEnergy;
mass = newEnergy / (units.SPEED_OF_LIGHT * units.SPEED_OF_LIGHT);
}
public double get_mass() {return mass;}
public double setMass(double newMass) {
mass = newMass;
energy = newMass * (units.SPEED_OF_LIGHT * units.SPEED_OF_LIGHT);
}
}
public static void main(String[] args) {
Relativity relativity = new Relativity(
Integer.parseInt(args[1])
);
System.out.println(relativity.getEnergy())
}
}
(untested, as it has been a long time since I've touched any Java code)
