将二维数组打印到控制台时，值是随机设置的

public class ArrayPrinter {
    public static void main(String[] args) {
        int[][] array = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                System.out.print(array[i][j] + " ");
            }
            System.out.println();
        }
    }
}

import java.util.Random;

public class RandomArray {
    public static void main(String[] args) {
        int[][] array = new int[3][3];
        Random random = new Random();

        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                array[i][j] = random.nextInt(100); // 生成0到99之间的随机数
            }
        }

        // 打印二维数组
        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                System.out.print(array[i][j] + " ");
            }
            System.out.println();
        }
    }
}
