Difference between length() and length in java



This is a tricky question asked in java interviews.
 The main purpose of both are same as they are used for calculating the length but the difference can be understand by the definition of both mentioned below:  
The length() method is used for calculating the length of the String variable in java.
The length property is used to calculate the length of the Array  in java.
Example:-
public class ArrayTest
{
  public static void main(String[] args)
                     {
    int[] test = {12,1,4};
    String test2 = "Hoo";
    System.out.println(test.length);
    System.out.println(test2.length());
                     }
}
