當編譯該代碼僅示出最後一個輸入

Question

的分數時編譯該代碼僅示出最後一個輸入的分數

import java.util.*; 
    public class TestII { 
    static Scanner key = new Scanner (System.in); 
    static int countNa = 0; 
    static int countSc = 0; 
    static int numSc; 
    static int numNa; 
    static int [] scores = null; 
    static String [] names = null; 
    public static void main(String[] args) { 
     System.out.println("How many name and scores"); 
     System.out.print("N> "); 
     numNa = key.nextInt(); 
     System.out.print("S> "); 
     numSc = key.nextInt(); 
     names = new String [numNa]; 
     scores = new int [numSc]; 
     readNameScores(); 
     showNamesScores(); 
    } 
    public static void readNameScores(){ 
     for (int i = 0; i < names.length; i++){ 
      countNa++; 
      System.out.print("Name "+countNa+": "); 
      names [i] = key.next(); 
      for (int j = 0; j < scores.length; j++){ 
       countSc++; 

        if (countSc > scores.length){ 
         countSc = 0; 
         countSc++; 
        } 
       System.out.print("\tScore "+countSc+": "); 
       scores [j] = key.nextInt(); 
       } 
      } 
    } 
    public static void showNamesScores(){ 
     System.out.println(""); 
     for (int i = 0; i < names.length; i++){ 
      System.out.print(names [i]+"\t"); 
      for (int j = 0; j < scores.length; j++){ 
       System.out.print(scores [j]+" "); 
      } 
     } 
    } 
}

Answer 1

你的scores數組使得只有一個名字的分數。您應該將其更改爲二維數組。

static int [][] scores = null; 
... 
names = new String [numNa]; 
scores = new int [numNa][numSc]; 
... 
public static void readNameScores(){ 
    for (int i = 0; i < names.length; i++){ 
    System.out.print("Name "+(i+1)+": "); 
    names [i] = key.next(); 
    for (int j = 0; j < scores.length; j++){ 
     System.out.print("\tScore "+(j+1)+": "); 
     scores[i][j] = key.nextInt(); 
    } 
    } 
}
