如何使用方法修复“实际和形式参数列表的长度不同”？

Question

我正在使用进行赋值的方法，但我无法通过getBidAmounts方法。我不断收到这种错误：

required: int[],int found: int[] reason: actual and formal argument lists differ in length。

public static void main (String[] args) {

      double budget = getBudget();
      final double MIN_BID_AMOUNT = 0;

      final int MIN_NUM_BIDS = 0;
      final int MAX_NUM_BIDS = 100;
      int numBids = getNumBids(MIN_NUM_BIDS, MAX_NUM_BIDS);
      int[] bids = new int[numBids];
      getBidAmounts(bids);
      }

      public static void getBidAmounts (int[] bidAmounts, int minBidAmount) {
         for (int i = 0; i < bidAmounts.length; i++) {
         do {
            bidAmounts[i] = Integer.parseInt(JOptionPane.showInputDialog("Enter the Amount of Bid #" + (i+1) + ": "));
            if (bidAmounts[i] <= minBidAmount)
            {
               JOptionPane.showMessageDialog(null, "Enter a Valid Bid Amount Above" + minBidAmount + ".");
            }
         } while (bidAmounts[i] <= minBidAmount);
        }
     }

这应该允许用户将事物输入到数组中。

调用getBidAmounts(bids);时，您只提供一个参数，而

public static void getBidAmounts (int[] bidAmounts, int minBidAmount)需要两个参数。

因此，将由getBidAmounts(bids);更改为getBidAmounts(bids, MIN_NUM_BIDS );。

在这里，MIN_NUM_BIDS将表示minBidAmount方法内的参数getBidAmounts（第二个）。
