Java array.length method

Question

I am getting error: Undefined symbol:length.

import java.util.*;

class ssss

{

  public static void main(String args[])

    {

     int a[]={1,2,3,4};
     Sy         


        

Answer 1

length is a public attribute not a method in array. Therefore, we access the length of array as :

int x = a.length;

and not as,

int x = a.length();
