我有一個非常奇怪的陣列打印。代碼和輸出如下。
非常奇怪的陣列打印
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:

我不知道是什麼原因造成這個問題,任何幫助,將不勝感激。
[什麼是調試器,它如何幫助我診斷問題?](https://stackoverflow.com/q/25385173/5221149)---迄今爲止我們可以給你的最好的幫助是建議你學習如何調試代碼,這樣你就可以自己發現問題,而不必等待其他人爲你調試。你也學到更多。 – Andreas
我可以通過換行'column.add(number);' 和'number ++;'來修正數字。不過,我對你試圖用字母做什麼感到困惑。 –
