Why is this program array.length () is not successful ?

If that, please help me doubts where noted . Thank you.

import java.util.*;
  
  public class Test
  {
  		public static void main(String [] args)	
  		{
           int a = 20;
           Integer b = new Integer(20);        
           Integer i =10;
           
           List<Integer> list = new ArrayList<Integer>();
           list.add(i);
           list.add(b);
           list.add(new Integer(30));
           
           System.out.println(list);
           
           Integer[] array = new Integer[list.size()];
           list.toArray(array);
           for(Integer e: array)
           {
          			System.out.println(e);	
           }
                  
           int brray[] = new int[array.length()]; //array是个数组，为什么array.length()不成功呢？        
             				
  		}
  }

------ Solution ------------------------------------- -------
array.length not array.length ().
------ Solution ------------------- -------------------------
array length method does not have the length property
------ Solution - ------------------------------------------
length is an attribute , not a The method can not be used ( ) .
array length about the landlord may have a look this post, very well.
