如何解决此程序代码(java)中的每个编译错误?

我一直试图解决这个问题,而且我对java的模块不太熟悉并且调用ref。有人可以帮助我使这个程序工作吗?这很令人困惑。它在java中通过引用传递有很多问题,以及我在那里的任何额外错误。我不断收到类似不兼容的错误,但找不到符号。

    //This program is designed to have the user enter 10 golf scores, then display them in        ascending order.

 import java.util.Scanner;

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

    //Declares the size for the variable, which is 10
    int SIZE = 10;

    //Declares the array and utilize it with SIZE variable
    int[] scores = new int[SIZE];

    getScores(scores, SIZE);

    insertionSort(scores, SIZE);

    displayScores(scores, SIZE);
   }

public static int[] getScores(int scores[], int SIZE)
{
    // Scanner object for keyboard input.
    Scanner keyboard = new Scanner(System.in);

    //Declares the index as a counter
    int index;

    //Get the scores for each golf player
    for ( index = 0; index <= SIZE - 1; index++)
    {
        System.out.print("Enter the golf scores for player " + (index + 1)   + ": ");
        scores[index] = keyboard.nextInt();
    }
    return scores[index];
}


public static int[] insertionSort(int array[], int SIZE)
{
    int unsortedValue;
    int scan;
    int index;

    for ( index = 1; index <= SIZE -1; index++)
    {
        unsortedValue = scores[index];
        scan = index;
        while (scan > 0 &&  array[scan - 1] < array[scan])
        {
            swapModule();

            scan = scan - 1;
        }
        array[scan] = unsortedValue;
    }
    return array[scan];
}


public static int[] swapModule(int a, int b)
{
    int temp;

    temp = a;
    a = b;
    b = temp;
    return b;
}

public static int[] displayScores(int scores[], int SIZE)
{
    int index;

    System.out.print("The scores are now displayed: ");
    for (index = 0; index <= SIZE - 1; index++)
    {
        System.out.print(scores[index]);
    }
}
}

答案 0 :(得分:2)

我注意到的前三件事是:

  • 在getScores方法中,您返回一个由索引变量的位置而不是数组设置的int值(顺便说一下,如果它起作用,它将抛出一个ArrayIndexOutOfBoundsException)

  • 您在insertedSort方法中调用的swapModule()方法没有所需的参数

  • displayScores方法必须返回一个int [],但你没有返回任何内容。

同样,正如其他人所说,编译器会告诉你错误的原因。这些只是我通过查看代码看到的一些错误。希望它有所帮助!
