非常奇怪的陣列打印

Question

我有一個非常奇怪的陣列打印。代碼和輸出如下。

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

代碼與以下問題陣列。

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 + "."); 
    } 
} 

輸出：

A0 
A0 
A0 
A0 
A0 
A0 
A0 
A0 
A0

A1

A2 
A3

A3 
The table has been created with 5 Dot Coms, a table size of 5, and a Dot Com size of 5. 

的預期結果是這樣的：

A0 
B0 
C0 
D0 
E0 
A1 
B1 
C1 
D1 
E1 
A2 
B2 
C2 
D2 
E2 
A3 
B3 
C3 
D3 
E3 
A1 
B4 
C4 
D4 
E4 

我不知道是什麼原因造成這個問題，任何幫助，將不勝感激。

查看程序再次theAlphabetIndex永遠不會增加，可以將其設置爲0，但它不會增加爲size2值爲5. theAlphabetIndex=0你只得到A（..）是在0指數。
