    Default help with a last bit of my code!!

    Ok so this is my code


    import java.util.Scanner;

    public class AllisonBrittanyCalculateGrades {

    public static void main(String [] args) {

    Scanner sc = new Scanner(System.in);

    double sum = 0;
    double lowest = 100;
    double score;
    double ast;
    double grad;

    for(grad = 1; grad <= 5; grad++) {

    System.out.println("Enter asignment grades");
    score = sc.nextDouble();

    sum = sum + score;

    if (score < lowest)
    {
    lowest = score;
    }
    }
    sum = sum - lowest;
    sum = sum/4;

    System.out.println("Your assignment average is " + sum);

    System.out.println("Enter first exam grade");
    double grade1 = sc.nextDouble();

    System.out.println("Enter second exam grade");
    double grade2 = sc.nextDouble();

    System.out.println("Enter lab grade");
    double lab = sc.nextDouble();

    System.out.println("Enter final exam grade");
    double fe = sc.nextDouble();

    double average = sum*.20 + grade1*.15 + grade2*.20 + lab*.20 + fe*.25;
    System.out.println("The weighted average is " + average);

    if (average <= 100 && average >= 90) {
    System.out.println("You will receive an A");
    }
    if (average < 90 && average >= 80) {
    System.out.println("You will receive an B");
    }
    if (average < 80 && average >= 70) {
    System.out.println("You will receive an C");
    }
    if (average < 70 && average >= 60) {
    System.out.println("You will receive an D");
    }
    if (average < 60) {
    System.out.println("You will receive an F");
    }

    Scanner scanner = new Scanner(System.in);

    System.out.println("Do you want to calculate for another student? Please type true or false");
    String truefalse = scanner.nextLine();
    }
    }



    the issue I'm having is I need to be able to have it say bye bye if the user types in false and have it start from the beggining if the user types in true. I have tried everything I can think of and I have to turn this program in by the end of the say. Please help!

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    have it say bye bye if the user types in false and have it start from the beggining if the user types in true
    That's usually done by wrapping the code to be repeated in a while loop. The while's condition should test what the user entered and either continue or exit as per the program's requirements.
    If you don't understand my answer, don't ignore it, ask a question.

    Continuing from where you left off, I can only suggest that you:
    1. Declare a boolean type of truefalse first
    2. Place all your code in a while loop
    3. Don't need to create another object of your Scanner class.
    4. Replace -
     String truefalse = scanner.nextLine();
    with
     truefalse = sc.nextBoolean();
    . Something like this:
    boolean truefalse = true;
    while (truefalse){
    //TheRestOfYourCodeGoesHere
    //Finally
    System.out.println("Do you want to calculate for another student? Please type true or false");
    truefalse  = sc.nextBoolean();
    }

    I hope this helps.
