java - 如何使用方法修复 "actual and formal argument lists differ in length"？

Question

我正在使用方法进行分配，但无法通过 getBidAmounts 方法。我不断收到此类错误:

必需:int[]，int 找到:int[] 原因:实际参数列表和形式参数列表长度不同。

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);
        }
     }

这应该允许用户将内容输入到数组中。

Answer 1

当您调用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。

所以，改变 getBidAmounts(bids);至getBidAmounts(bids, <强> MIN_NUM_BIDS ); .

在这里，MIN_NUM_BIDS将代表参数 minBidAmount (第二个)里面getBidAmounts方法。
