如何从二维数组中仅打印一列? [英] How can i print just a single column from a two dimensional array?

问题描述

我正在编写此程序，我只需要打印二维数组的一列，而不能全部打印.

I have this program im writing and i have to print just one column of a two dimensional array, not both.

for (int i = 0; i < sjf.length; i++)
{
    for(int j = 0; j < sjf[i].length; j++)
    {
        System.out.printf("%5d%4s   ", sjf[i][j], "|");
    }
    System.out.println();
}
System.out.println();

推荐答案

例如，您要打印第五列:

For example you want to print the fifth column:

int column = 5;
for (int[] row : sjf) {
       System.out.printf("%5d%4s   ", row[column], "|");
}
System.out.println();
