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();

Answer 2

@TheLostMind answer

change

 int x = a.length(); 

to

int x = a.length; 

Answer 3

length() is not a valid method. So you can try like this

class ssss
{
    public static void main(String args[])
    {
        int a[]={1,2,3,4};
        System.out.println(a[1]);
        int x = a.length;  
        System.out.println(x);
    }
}

Answer 4

length is a field for arrays and not a method. Use a.length
