打印二维数组并为奇数打印 *

Question

enter image description here why does the console print my 2D array in a row?

Answer 1

You're using System.out.print which doesn't append a newline to the end of your output, meaning it will just keep printing everything to the same line.

You can add the line System.out.println() inside your top-level loop, but after your inner loop, and it will log each 2nd-level array to it's own line.
