To get the number of dimensions

     

public class Main {
  public static void main(String args[]) {
    String[][] data = new String[3][4];
    System.out.println(getDimension(data));
  }

  public static int getDimension(Object array) {
    int dim = 0;
    Class c = array.getClass();
    while (c.isArray()) {
      c = c.getComponentType();
      dim++;
    }
    return (dim);
