java - 如何多次水平打印二维数组

Question

我正在使用 java，我想根据用户输入多次水平打印二维数组。但是，我的阵列是垂直打印的，有人可以帮忙吗？

    n=3; //user input
    char[][] board = new char[2][3];
    char[][] f = new char[board.length][n * board[0].length];
    for (int i = 1; i < n + 1; i++) {
        int Start = (i * board[0].length) - board[0].length;
        int End = i * board[0].length;
        for (int row = 0; row < f.length; row++) {
            for (int col = nStart; col < nEnd; col++) {
                f[row][col] = board[row][col - nStart];
                System.out.print(f[row][col]);
            }
            System.out.println();
        }
    } 
For example board array = 
xx
xx
I would like 
xxxxxx
xxxxxx

如果你想水平打印二维数组，你必须在下一行之前重复打印行 n 次:

int n = 3; // user input
char[][] board = new char[][] { { 'x', 'x', 'x' }, { '0', '0', '0' } }; //example board

for (int row = 0; row < board.length; row++)
{
    for (int i = 0; i < n; i++)
    {
        for (int col = 0; col < board[row].length; col++)
        {
            System.out.print(board[row][col]);
        }
        System.out.print("\t"); //arrays separated by tab
    }
    System.out.println();
}

输出:

xxx xxx xxx 
000 000 000
