Stuck on errors (Java)

1

Please assist,

Not sure where the error is coming from or what I’m missing, this is from the following question

Write the complete java program called Temperature that includes a for loop structure, prompting the user to enter 5 temperature values. The program should add up each temperature entered within the loop and this is stored in a variable called total. Using a system statement, output the total temperature value and the average temperature value. Use the sample output below as a guide:
The total temperature =
The average temperature =

<p>import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner temp = new Scanner (System.in);
        double total = 0;
        for(int=1;int<=5;int++);
        {
            System.out.println ("Enter temperature #" + temp +":");
            double temperature = temp.nextDouble ();
            total = temperature;

        }
        System.out.println("The total temperature =" +total);
        System.out.println("The average temperature=" +(double)(total/5));
    }
}
<p/>

You missed few things as follows -

for loop missing i initialization,
also extra semicolon at end of for

“Enter temperature #” + i + “:”

total = total + temperature;

Hi,

Thanks for the feedback.

So I shouldn’t use temp?

I changed it from “i” as I was getting an error and I’m still getting the error

Scanner object (in your case temp) only used while reading input
it should not be used in System.out.println

use i instead so that it will show, i’s value 1 2 3 4 5
Enter temperature #1
Enter temperature #2
Enter temperature #3
Enter temperature #4
Enter temperature #5

I always declare like- Scanner sc= new Scanner (System.in);
then use it as- sc.nextDouble()

import java.util.Scanner;

public class Temperature {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double total = 0.0;
        double temperature = 0.0;

        for (int t = 1; t <= 5; t++) {
            System.out.print("Enter temperature #" + t + ": ");
            temperature = scanner.nextDouble();
            total = total + temperature;
        }

        System.out.println("The total temperature = " + total);
        System.out.println("The average temperature = " + (total / 5));
    }
}

Thanks, EricNC,

I managed to figure out why the error in my code

jGrasp needed me to do the following

<p>
import java.util.Scanner;
</p>
 
And with the above I had

import javax.swing.JOptionPane;
