打印可变大小的字母X的代码

import java.util.Scanner;

class AlpX {

    public static void main(String[] args) {

        int x ;
        Scanner s = new Scanner(System.in);
        System.out.println("打印字母x");

        int y = 0;
        Scanner s1 = new Scanner(System.in);
        System.out.println("输入整数倍：");
        y = s1.nextInt();


        int[][] arr = new int[y][y];

        for (int i = 0; i < arr.length; i++) {
            for (int j = 0; j < arr.length; j++) {
                if (i==j){
                    System.out.print(" ");
                }
                if (i==y-1-j){
                    System.out.print(" ");
                }
                System.out.print("*");
            }
            System.out.println(" ");
        }

        s.close();
    }
}

运行结果
