JAVA小白求助，简单图形输出

Question

根据输入整数，如n=5，输出以下n*n个数字图形

1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25

Answer 1

就是用for循环来打印：

public class Test {
    public static void print_square(int n) {
        for (int i = 1; i < n * n; i += 5) {
            for (int j = i; j < i + 5; ++j) {
                System.out.print(j+" ");
            }
            System.out.println();
        }
    }
    public static void main(String[] args) {
        Test.print_square(5);
    }
}
