2维数组和在java中使用Scanner

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int rows = 3; // 2维数组的行数
        int columns = 3; // 2维数组的列数
        int[][] array = new int[rows][columns];
        
        // 逐行读取数据
        for (int i = 0; i < rows; i++) {
            String line = scanner.nextLine();
            String[] values = line.split(" "); // 假设数据以空格分隔
            // 将每个值转换为整数，并存入2维数组
            for (int j = 0; j < columns; j++) {
                array[i][j] = Integer.parseInt(values[j]);
            }
        }
        
        // 打印2维数组
        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();
    }
}
