Question

我的阵列打印非常奇怪。代码和输出如下。

public class AdvDotComLauncher {
    public static void main(String[] args) {
        AdvDotComTable table = new AdvDotComTable();
        table.createTable(5,5, 5);
    }
}

下面有问题的数组代码。

import java.util.ArrayList;


public class AdvDotComTable {
    public void createTable(int size, int dotComAmount, int dotComSize) {
        //Holds the DotComs that will be randomly put onto the map
        String[] dotComs = {"Pets.com", "Amazon.com", "Target.com", "Apple.com", "Microsoft.com", "Steampowered.com"};
        //Holds the rows and columns
        ArrayList<Character> row = new ArrayList<Character>();
        ArrayList<Integer> column = new ArrayList<Integer>();
        column.add(0);
        char[] theAlphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".toCharArray();
        //Makes sure the Dot Coms will fit
        if (dotComAmount >= dotComs.length || dotComAmount / dotComSize > size) {
            System.out.println("There are too many dot coms! Please enter different amounts.");
        }
        //Used in the while loop to make sure that the correct amount of columns are created
        int done = size * size;
        //Used to get an index value in theAlphabet
        int theAlphabetIndex = 0;
        //Used to add columns
        int number = 0;
        //Used to tell when to create a column
        int size2 = size;
        //Starts creating rows and columns
        while (done > 0) {
            row.add(theAlphabet[theAlphabetIndex]);
            if (size2 == 0) {
                size2 = size;
                column.add(number);
                number++;
                theAlphabetIndex++;
            }
            System.out.println(row.get(number) + "" + column.get(number));
            size2--;
            done--;
        }
        System.out.println("The table has been created with " + dotComAmount  + " Dot Coms, a table size of " + size + ", and a Dot Com size of " + dotComSize + ".");
    }
}

输出：

我不知道是什么导致了这个问题，我们将不胜感激。

再次查看您的程序theAlphabetIndex永远不会增加，您将其设置为0但不会因size2的值为5而增加。作为theAlphabetIndex=0，您只能获得 A（..），其为0索引。
