I am trying to use return value in this program but it won't compile
<p>I try to make total scores and weighted scores into return value and the parameters are passed from the scanner console, and the return values are called from the static void method.</p>

<pre><code>import java.util.*;

public class Grades {
    public static void main (String[] args) {

        intro();

        Scanner console = new Scanner(System.in);

        int totalScoreMain = totalScore(score, curveNumber);
        double weightedScoreMain = weightedScore(weight, score, curveNumber);
        double weightedScore2Main = weightedScore2(weight2, sections, sumScore);

        for(int i = 1; i &lt;= 2; exam++); {
            System.out.println("Exam i");
            exam();
        }
        homework();
}

public static void intro () {

        System.out.println("This program reads exam/homework scores");
        System.out.println("and reports your overall course grade.");
        System.out.println();
    }


public static void exam () {

        System.out.print("What is its weight (0-100)?");
        double weight = console.nextInt();
        System.out.print("Score earned?");
        int score = console.nextInt();
        System.out.print("Was there a curve (1=yes, 2=no)?");
        int curve = console.nextInt();
            if (curve == 1) {
                System.out.print("How much was the curve?");
                int curveNumber = console.nextInt();    
            } else if (curve == 2) {
                int curveNumber = 0;
            }

        totalScore(score, curveNumber);
        weightedscore(weight, score, curveNumber);

        System.out.println("Total points = " + totalScoreMain + "/" + "100");
        System.out.println("Weighted score = " + weightedScoreMain + "/" + weight);
    }

public static int totalScore (int score, int curveNumber) {

        int totalScore = Math.min(score + curveNumber, 100);
        return totalScore;
    }

        double weightedScore = (score + curveNumber) * weight/100;
        return weightedScore;
    }

public static void homework () {

        System.out.print("What is its weight (0-100)?");
            int weight2 = console.nextInt();
        System.out.print("Number of assignments?");
            int number = console.nextInt();
            int sumScore = 0;
            int sumMax = 0;

        for(int i = 1; i &lt;= number; i++) {
            System.out.println("Assignment " + i + "score and max?");
                int aScore = console.nextInt();
                int aScoreMax = console.nextInt();

                sumScore = sumScore + aScore;
                sumMax = sumMax + aScoreMax; }

            System.out.print("How many sections attended?");
                int section = console.nextInt();
                int sections = Math.min(3 * section, 20);
            System.out.println("Section points = " + sections);

            weightedScore2(weight2, sections, sumScore);

                System.out.println("Total points = " + (sections + sumScore) + "/" + sumMax);
                System.out.println("Weighted score = " + weightedScore2 + "/" + weight2);
        }


public static double weightedScore2(int weight2, int sections, int sumScore) {

            int weightedScore2 = weight2/100 * (sections + sumScore);
            return weightedScore2;
        }
    }
