Java 知道数组的类别

​

public class Main {

​

  public static void main (String[] args){

​

    int[] iArr = new int[2];/** 来 自 N o w J a v a . c o m**/

​

    int[][] iiArr = new int[2][2];

​

    int[][][] iiiArr = new int[2][2][2];

​

​

    String[] sArr  = {"A", "B"} ;

​

    String[][] ssArr = {{"AA"}, {"BB"}} ;

​

    String[][][] sssArr = {} ; // A 3D empty array of string

​

​

    // Print the class name for all arrays  

​

    System.out.println("int[]:" + getClassName(iArr));

​

    System.out.println("int[][]:" + getClassName(iiArr));/**from n o w  j a v a  . c o m**/

​

    System.out.println("int[][][]:" + getClassName(iiiArr));

​

    System.out.println("String[]:" + getClassName(sArr));

​

    System.out.println("String[][]:" + getClassName(ssArr));

​

    System.out.println("String[][][]:" + getClassName(sssArr));

​

  }

​

​

  // Any java object can be passed to getClassName() method.

​

  // Since every array is an object, we can also pass an array to this method.
