# Java Help

 Zodiac delby · November 2, 2014 Hi Simon,I hope you can help on this question also , appreciated thank you.1.       Write a program that takes three double values x0, v0, and t from the user and prints the value x0 +v0t +g t2/2, where g is the constant 9.78033. This value is the displacement in meters after t seconds when an object is thrown straight up from initial position x0 at velocity v0 meters per second.  Sample run:Enter the value of x0, v0 and t: 0 2 2The displacement in meters after 2 seconds when an object is thrown straight up from initial position 0 at velocity 2meters per second is: 23.56066Answer :

 Zodiac delby · November 2, 2014 No I did as below , but I'm not sure it's right ... package problem_3;import java.util.Scanner;public class Problem_3 {    public static void main(String[] args)     {        Scanner s =new Scanner(System.in);        int N1D1,N2D2,SUM,SUB,MUL,DIV;        double result;        System.out.println("Enter the numerator and denominator of the first fraction:");        N1D1=s.nextInt();        N2D2=s.nextInt();        System.out.println("Enter the numerator and denominator of the second fraction:");        N2D2=s.nextInt();        System.out.println("The sum is :"+N1D1+N2D2);        System.out.println("The subtraction is :");        System.out.println("The multiplication is :");        System.out.println("The division is :");    }    } Zodiac delby · November 2, 2014 if you want to help you can do that , if not , it's not the right place to show that your are super genius . and it's not a  place to share jokes , it's a place to learn.
