Distance Traveled
and
distance file both are java
thanks a alot

Programming Cha enges 2. Distance Traveled The distance a vehicle travels can be calculated as follows Distance Speed Time For example, if a train travels 40 miles-per-hour for three hours, the distance traveled is 120 miles. write a program that asks the speed of a vehicle (in miles r and the number of hours it has traveled. It should use a loop t display the vehicle has distance a traveled for hour of a time period specified by the user. For example, a vehicle is traveling at 40 mph for a three-hour time period, it should display a report similar to the one that follows: Distance Traveled 40 80 120 gative number for speed and do not accept any Input Validation: Do not accept a ne less than 1 for time traveled. 3. Distance File Challenge 2 (Distance so it Modify the program you wrote for Programming Travel text writes the report to a file instead of the screen. Open the file in Notepad or another editor to confirm the output. on 1000 in

import java.util.Scanner;

public class DistanceTravelled {

public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
  
int speed;
while(true)
{
System.out.print("Enter vehicle speed (in miles-per-hour): ");
speed = sc.nextInt();
if (speed < 0)
{
System.out.println("Enter a positive value for speed. Try again!");
}
else
{
break;
}
}
  
int time;
while(true)
{
System.out.print("Enter time in hours: ");
time = sc.nextInt();
if (time < 1)
{
System.out.println("Enter a value greater than equal to 1 for time. Try again!");
}
else
{
break;
}
}
  
  
System.out.println("Hour Distance Travelled");
System.out.println("--------------------------");
for(int i = 1; i <= time; i++)
{
System.out.println(i + " " + i*speed);
}
sc.close();
}
}
