length() and length.

[Nabila Mohammad]

I understand length() is a method in String class to find the length of the string.
But what is length.
For eg.

  
class a
{  
    public static void main(String[] args)
    {   
    int numArgs=args.length;
   ......................
    }
}
  

Why can't we use length() and where his this length located?

Because, in Java, to get the size of an Array, the language designer prefer to define a field called length, instead of a method length (). The reason is unknown.
Since the length is a runtime property, it is not defined anywhere as an API. You can not change the size of an array

An array's public final field "length" is described in the Java Language Specification under 10.7 Array Members.
