내 메서드에 적합한 출력을 얻으려면 어떻게해야합니까?

Question

나는 퀴즈, 연구소, 실험실 출석, this- 퀴즈 추천하기 추천 중간 고사 표시 할 원하는 : 66 % 연구소 : 88 % 연구소 출석 : 81 % 중간 고사 : 해당 없음 전체 평균 : 최종 91 % 85 %. 하지만지고있어

출력 : 내가 달성하기 위해 노력하고있어 적합한 출력을 얻을 것이다 어떻게

66.0 
88.0 
81.0

Answer 1

이 수정 된 코드 &이/P O를 것으로 예상된다 :

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; 
    String quizzes= "Quizzes"; 
    String labs= "Labs"; 
    String lab_attendance= "Lab_attendance"; 
    String midterm= "Midterms"; 
    int[] quizArray = null; 
    int[] labArray = null; 
    int[] attendance = null; 
    int[] midterms = null; 
    int quizgrade = 0; 
    int labgrade = 0; 
    int attendance_1 = 0; 
    int midterms_1 = 0; 
    String name; 


    try { 
     scan = new Scanner(new File("C://Users//Desktop//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,maxGrade, quizzes); 


     } else if (name.equals("Labs")) { 
      labArray = new int[numScores]; 
      readScores(labArray, numScores, scan,maxGrade, labs); 

     } else if (name.equals("Lab_attendance")) { 
      attendance = new int[numScores]; 
      readScores(attendance, numScores, scan,maxGrade,lab_attendance); 

     } else if (name.equals("Midterms")) { 
      midterms = new int[numScores]; 
      readScores(midterms, numScores, scan,maxGrade, midterm); 

     } 

    } 

} 


public static void readScores(int[] scoreArray, int numScores, Scanner scan, int maxGrade, String name) { 
    for (int i = 0; i < numScores; i++) { 
     scoreArray[i] = scan.nextInt(); 
    } 
    average(scoreArray, numScores, maxGrade, name); 
} 

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(int[] scoreArray, int numScores,int maxGrade, String name) { 
    double sum = 0; 
    for (int i = 0; i < scoreArray.length; i++) { 
     sum += scoreArray[i]; 
    } 
    double average = Math.round((sum/numScores)*100/maxGrade); 

    System.out.println(name + ":" + average+" %"); 

    return average; 
} 
} 

을 그리고 결과 것은 :

Quizzes:66.0 % 
Labs:88.0 % 
Lab_attendance:81.0 % 
Midterms:91.0 %** 

Answer 2

당신은 실제로 당신이 아무것도를 인쇄하고 코드를 게시,하지만 당신이 원하는 것은 아마 System.out.format()하지 않았다.

Answer 3

이름을 Average로 전달하고 이름과 점수를 인쇄해야합니다. 고정 된 코드 아래에 제안을 보면, 찾고있는 입력을 제공합니다.

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[] attendance = null; 
    int[] midterms = null; 
    int quizgrade = 0; 
    int labgrade = 0; 
    int attendance_1 = 0; 
    int midterms_1 = 0; 
    String name; 


    try { 
     scan = new Scanner(new File("c:\\temp\\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,maxGrade, "Quizzes"); 


     } else if (name.equals("Labs")) { 
      labArray = new int[numScores]; 
      readScores(labArray, numScores, scan,maxGrade, "Labs"); 

     } else if (name.equals("Lab_attendance")) { 
      attendance = new int[numScores]; 
      readScores(attendance, numScores, scan,maxGrade, "Lab_attendance"); 

     } else if (name.equals("Midterms")) { 
      midterms = new int[numScores]; 
      readScores(midterms, numScores, scan,maxGrade, "Midterms"); 

     } 

    } 

} 


public static void readScores(int[] scoreArray, int numScores, Scanner scan, int maxGrade, String name) { 
    for (int i = 0; i < numScores; i++) { 
     scoreArray[i] = scan.nextInt(); 
    } 
    average(scoreArray, numScores, maxGrade, name); 
} 

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(int[] scoreArray, int numScores,int maxGrade, String name) { 
    double sum = 0; 
    for (int i = 0; i < scoreArray.length; i++) { 
     sum += scoreArray[i]; 
    } 
    double average = Math.round((sum/numScores)*100/maxGrade); 

    System.out.println(name + ":" + average); 

    return average; 
} 
} 

그리고 예상 출력하면 그것을 실행하는 경우 :

여기

Quizzes:66.0 
Labs:88.0 
Lab_attendance:81.0 
Midterms:91.0
