java - 二维数组将行打印为列java

Question

我们被要求打印这个二维数组，并将列作为行

例如:第一列是20,11,27，必须打印:

20
11
27

到目前为止，这是我的代码，我什至无法正常打印列，你们中有人知道问题是什么以及是否可以帮助我找到问题的解决方案吗？

public class TwoDimensionalArrays
{
public static void main (String args[])
{
    final int size1 = 2, size2 = 4, size3 = 5;
    int [][] numbers = {{20,25,34,19,33}, {11,17,15,45,26}, {27,22,9,41,13}};        
    int row = 0, col = 0;

        for(row = 0; row <= size1; row++); //loops through rows
        {
            for(col = 0; col <= size2; col++); //loops through columns
            {
                System.out.println(numbers[row][col]);
            }
        System.out.print("\n"); //takes a new line before each new print
        }
    }
 }

删除循环末尾的;

像这样:

for (row = 0; row <= size1; row++) //loops through rows
 {
   for (col = 0; col <= size2; col++) //loops through columns
    {
       System.out.print(numbers[row][col]+" ");
     }
    System.out.print("\n"); //takes a new line before each new print
  }

输出:

20 25 34 19 33 
11 17 15 45 26 
27 22 9 41 13
