索引匹配最大/最小分数Java

如何解决索引匹配最大/最小分数Java

我正在完成一项编码作业，并且接近完成，除了我的最终打印语句需要匹配名称和最大值和最小值的分数。

我已经能够使用两个 if 语句在两个句子中获得适当的值，但我对如何使我的索引正确以将名称与分数 w/max 和 min 对齐有点难。

除了数组和索引之外，我无法使用类或其他/不同的方法。

    //Create method StudentMax
private static int StudentMax(int[] scores) {
    int scoreMax = scores[0];
    for (int i = 0; i < scores.length; i++){
        if (scores[i] > scoreMax){
            scoreMax = scores[i];
        }
    }
    return scoreMax;
}

//Create method StudentMin
private static int StudentMin(int[] scores) {
    int scoreMin = scores[0];
    for (int i = 0; i < scores.length; i++){
        if (scores[i] < scoreMin) {
            scoreMin = scores[i];
        }
    }
    return scoreMin;
}

public static void main(String[] args) {

    //Call Scanner
    Scanner scan = new Scanner(system.in);

    //User Welcome
    System.out.println("Welcome to the student score sorter.");
    System.out.println("\nThis program will accept a number of student names and score values,then find the highest and lowest score.");
    System.out.println("\nThen will return the names and max/min scores.");


    //User Prompt Enter number of students
    System.out.println("\nHow many students would you like to enter: ");
    int StudentCount = scan.nextInt();

    //Create arrays: scores,StudentFirst,StudentLast
    int [] scores = new int[StudentCount];
    String [] StudentFirst = new String [StudentCount];
    String [] StudentLast = new String [StudentCount];


    for (int i = 0; i < scores.length; i++) {
        System.out.println("\nStudent " + (i+1)+":");
        System.out.println("\nEnter Student's name:");
        StudentFirst[i] = scan.next();
        StudentLast[i] = scan.next();
        System.out.println("\nEnter Student's score (0-100):");
        scores[i] = scan.nextInt();
    }
    

    int max = StudentMax(scores);
    int min = StudentMin(scores);
    


    for (int i = 0; i < scores.length; i++) {
        System.out.println("\n"+StudentFirst[i] + " " + StudentLast[i] +":      " + scores[i]); 
    }
    
    
    for (int i = 0; i < scores.length; i++)  {
        if (scores [i] == max) {
            System.out.println("\n"+ StudentFirst[i] +" "+ StudentLast[i] + " has the highest score => " +max+ " and " + StudentFirst[i]+" " + StudentLast[i]+ " has the lowest => " +min);         
        }
    }
    
    
    
    //This is the sentence format that I need to make work,but I am struggling to understand how to align the index for names and scores. 
    //System.out.println("\n"+StudentFirst[i] +" "+ StudentLast[i]+ " has the highest score => " +max+ " and " +StudentFirst[i] +" "+ StudentLast [i]+ " has the lowest score => " +min);
    
    
     
    
    


    //Scan Close
    scan.close();
    //Close Program
}

}

解决方法

传回索引而不是值

private static int StudentMin(int[] Scores) {
    int ScoreMin = Scores[0];
    int index = 0;
    for (int i = 0; i < Scores.length; i++){
        if (Scores[i] < ScoreMin) {
            ScoreMin = Scores[i];
            index = i;
        }
    }
    return index;
}

那你以后就可以用了

int index = StudentMax(Scores);

System.out.println("\n"+ StudentFirst[index] +" "+ StudentLast[index] + " has the highest score => " +Scored[index]);  

注意请注意Java命名约定
