我得到一個不同的output.The輸出我希望是 - 測驗:66% 實驗室:88% 實驗室出勤率:81% 期中考試:91% 決賽:不適用 整體平均:85%。 但我發現了獲得不同的輸出

我的方法正規化是假設得到的百分比,然後轉到平均法。我將這種方法稱爲quizArray,labArray,出席率,midterms以獲得每個人的成績。
import java.io.*;
import java.util.*;
public class FindGrade {
public static final int NUM_SCORE_TYPES = 5;
public static void main(String[] args) {
Scanner scan = null;
int[] quizArray = null;
int[] labArray = null;

int midterms_1 = 0;
String name;
try {
scan = new Scanner(new File("input.txt"));
} catch (FileNotFoundException e) {
e.printStackTrace();
return;
}
// each iteration is for single exam type (ie: Quizzes is the 1st one)
for (int i = 0; i < NUM_SCORE_TYPES; i++) {
name = scan.next();
int numScores = scan.nextInt();
int maxGrade = scan.nextInt();
if (name.equals("Quizzes")) {
quizArray = new int[numScores];
readScores(quizArray, numScores, scan);
} else if (name.equals("Labs")) {
labArray = new int[numScores];
readScores(labArray, numScores, scan);
} else if (name.equals("Lab_attendance")) {
attendance = new int[numScores];
readScores(attendance, numScores, scan);
} else if (name.equals("Midterms")) {
midterms = new int[numScores];
readScores(midterms, numScores, scan);
}
}
}
public static void readScores(int[] scoreArray, int numScores, Scanner scan) {
for (int i = 0; i < numScores; i++) {
scoreArray[i] = scan.nextInt();
}
average(scoreArray, numScores);
}
public static int normalize(int[] scoreArray, int maxGrade) {
int total = 0;
for (int i = 0; i < scoreArray.length; i++) {
total += scoreArray[i];
}
int percent = Math.round(total * 100/maxGrade);
return percent;
}
public static double average(double[] scoreArray, int numScores) {
double sum = 0;
for (int i = 0; i < scoreArray.length; i++) {
sum += scoreArray[i];
}
double average = sum/numScores;
return average;
}

你'在源代碼中到底缺少一個'}。 –
你在哪裏輸出?你在哪裏調用'normalize'和'average'方法? – Hannes
我的輸出在頂部。 – user124557
