在java中如何将2个键盘输入转换为2维数组？

import java.util.Scanner;

public class KeyboardInputTo2DArray {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.print("请输入数组的行数：");
        int rows = scanner.nextInt();

        System.out.print("请输入数组的列数：");
        int columns = scanner.nextInt();

        int[][] array = new int[rows][columns];

        System.out.println("请输入数组元素：");
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                array[i][j] = scanner.nextInt();
            }
        }

        System.out.println("输入的2维数组为：");
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                System.out.print(array[i][j] + " ");
            }
            System.out.println();
        }

        scanner.close();
    }
}
