Thread: Distance traveled problem

I am extremely new to java and having a hard time grasping it for my summer class. I am stuck on one problem so if anybody could help that would be great!

The distance a vehicle travels can be calculated as follows:
Distance = Speed * Time

Write a program that asks the user for the speed of a vehicle (in MPH) and the number of hours they traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 MPH for a three hour time period, it should show something like this:

Hour Distance Traveled
-----------------------------------
1 40
2 80
3 120

Input Validation: Do not accept a negative number for speed and do not acept any value less than 1 for time traveled


This is what I Have so far...


package lab4;

public class num2
{
public static void main(String[] args)
{

final int Time_Incrememnt = 1;

int d;
int s;
int t;
int i;
String input;

System.out.println("What is the speed of the vehicle in MPH?");

s = keyboard.nextInt();

while (s <= 0)
{

System.out.print("Your speed must be greater than zero. Please re-enter.");

}

System.out.print("Enter the number of hours that you have traveled: ");

t = keyboard.nextInt();


while (t <= 1)
{

System.out.print("Your hours must be at least 1 or more. Please re-enter.");


System.out.println("Hours Distance Traveled");
System.out.println("--------------------------------");

for (i = 1; i <= t; i++)

d = s*t;


}
}

}

That one is not finished at the end. I've had trouble getting it to correctly compute the distance traveled and get the hours as displayed in the example. It asks the right questions and everything I just can't get the final chart
