初始化一个四行三列的二维数组，将该数组按照行列的方式进行输出

public class JavaApplication {
public static void main(String[] args) {
Integer[][] numbers = new Integer[3][4];
Integer[] columnA = {1, 2, 3, 4};
Integer[] columnB = {5, 6, 7, 8};
Integer[] columnC = {9, 10, 11, 12};
numbers[0] = columnA;
numbers[1] = columnB;
numbers[2] = columnC;
for (int i = 0; i < numbers.length; i++) {
for (int j = 0; j < numbers[i].length; j++) {
System.out.print(numbers[i][j] + " ");
}
}
}
