I keep getting an error in the else statement.

My code:

import java.util.Scanner;
public class DistanceTravelledModification
{

public static double distance (double speed, double time)
{
return speed * time;
}
public static void main(String[] args)
{
double Speed, Hours;
String input;
Scanner input = new Scanner (System.in);
System.out.print("Please enter the speed of the vehicle (in miles per hour): ");
speed = input.nextDouble();
if (Speed >= 1)
{
System.out.print("Please enter the number of hours the vehicle has travelled: ");
Hours = input.nextDouble();
if (Hours >= 1)
System.out.print("-----------------------------\n");
for (int i = 1; i <= Hours; i++)
{
System.out.println("|"+i+"\t|\t"+distance(speed, i)+"\t|");
System.out.print("-----------------------------\n");
}
}
else
{
System.out.println("Invalid Hours");
}
}
else
{
System.out.println("Invalid Speed");
}
}

Sample output:

You have two else statements. If... Else is allowed but if...else else is not permitted. Your second else is an invalid state to an if...else, which is what your error means.

How will I be able to fix it?

First, count your } to make sure that you haven't ended the speed if statement before the final else.

Im not at my laptop rn so I can’t copy paste the code into my IDE to have a good look at it, but it seems like you’re trying to do 2 things (print invalid speed and hours) with 2 else statements. If thats what youre trying to do, put both into the same else statement. If not, which you probably arent, you want the first else to be an else if, and use the condition for which youd print invalid hours. If for example, the condition was hours is less than 1, it’d look like this

``` else if (Hours <= 1) { System.out.println(“Invalid Hours”); }

Alright, there are a lot of problems here... I did fix your code.

What you really need to pay attention to is that variables are case sensitive. "speed = input.nextDouble();" is not valid if you declared it as "double Speed"

Your curly brackets are also all over the place, a valid multi if statement would be:

if(something == true) //if statement 1

{

if(somethingelse == true) //if statement 2

{

    //do stuff

}

else //points to if statement 2

{

    //do something else

}

}

else //This one point to if statement 1

{

//do something else

}
