Physics Program

What is the error.

';' expected. thats all it says

Code :

---

Class Force
{
Public int CalculateForce(double first, double second)
{
return first * second;
}
Public Static void main(String args[])
{
Force formula=new Force();
Scanner read=new Scanner(System.in);
double a=0;
double b=0;
a=read.nextDouble();
b=read.nextDouble();
system.out.println("The Force is " + formula.CaclulateForce(a,b));
}
}

---

I missed a colon at "Scanner read=new Scanner(System.in)"

now there is an error with the return first * second. it says "possible loss of precision"

Code :

---

Class Force
{
Public double CalculateForce(double first, double second)
{
return first * second;
}
Public Static void main(String args[])
{
Force formula=new Force();
Scanner read=new Scanner(System.in);
double a=0;
double b=0;
a=read.nextDouble();
b=read.nextDouble();
system.out.println("The Force is " + formula.CaclulateForce(a,b));
}
}

Sorry for all those bugs. Im not in front of my ide :(. Ok try this.

now for Scanner read=new Scanner(System.in); it says cannot find symbol - class Scanner. I'm really sorry for bothering you with all this. You are a really great guy for helping me this much. I hope you know that and I really appreciate it.

Did you import?

import java.util.*;

no. do i put that right before the code?

yes. Hope it works.

that work but now it says cannot find symbol - method CalculateForce(double,double) for system.out.println("The Force is " + formula.CaclulateForce(a,b));

formula.CaclulateForce(a,b));

Typo should be

formula.CalculateForce(a,b));

Code :

---

import java.util.Scanner;
 
public class Force{
 
public double CalculateForce(double first, double second){
return first * second;
}
 
public static void main(String args[])
{    
    double mass = 0;
    double acceleration = 0;
 
    Force formula = new Force();
    Scanner read = new Scanner(System.in);
 
    System.out.println("Enter Mass: ");
    mass = read.nextDouble();
 
    System.out.println("Enter Acceleration: ");
    acceleration = read.nextDouble();
 
    System.out.println("The Force is " + formula.CalculateForce(mass,acceleration));
}
}
