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 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);
    }
}
