Java 创建多维数组并获取其维数

​

public class Main {

​

/*

 from 时 代 J a v a - N o w J a v a . c o m 

*/

​

    static void f2D(double[][] tab) {

​

        System.out.println("Number of lines:" + tab.length);

​

        System.out.println("Number of columns:" + tab[0].length);

​

    }

​

​

    static void f3D(double[][][] tab) {

​

        System.out.println("Number of lines X:" + tab.length);

​

        System.out.println("Number of columns Y:" + tab[0].length);

​

        System.out.println("Number of depths Z:" + tab[0][0].length);

​

    }

​

​

​

    public static void main(String[] args) {

​

        double[][] var = new double[3][4];
