    Post Cannot get the correct output

    Hello guys, I need your help. I want to know why the average score and grade are wrong? Please give me a hint how to solve this problem. Thanks in advance.

    Output
    Enter your quiz 1 score: 4
    Enter your quiz 2 score: 4
    Enter your quiz 3 score: 4
    The average score is: 0.0
    The quiz grade is: A

    import java.util.Scanner;
    public class Questiontwo 
    {
        public static void main(String [] args)
        {
        	Scanner input = new Scanner(System.in);
        	float score = 0;
        	float averagescore = 0;
        	String grade = "A";
     
        	for (int i = 1; i < 4; i++)
        	{
        		System.out.print("Enter your quiz " + i + " score: ");
        		score = input.nextFloat();
        	}
     
        	System.out.println("The average score is: " + averagescore);
        	System.out.println("The quiz grade is: " +grade);
        }
     
        public static float GetAverageScore(float averagescore, float score)
        {
        	averagescore = averagescore + score;
        	return averagescore;
        }
     
        public static String GetQuizGrade(float averagescore, String grade)
        {
        	if (averagescore >= 8 && averagescore <= 10)
        	{
        		grade = "A";
        		return grade;
        	}
     
        	else if (averagescore >= 5 && averagescore <= 7.99)
        	{
        		grade = "B";
        		return grade;
        	}
     
        	else if (averagescore >= 0 && averagescore <= 4.99)
        	{
        		grade = "C";
        		return grade;
        	}
     
        	else
        	{
        		grade = "F";
        		return grade;
            }   
        }
    }

    From your code it's evident that GetAverageScore and GetQuizGrade methods are not used. You are only doing a simple for loop, overwriting at every cycle the score variable and without doing any particular calculation. So what can you expect from this?
