if String is an array of characters,why "length( );" is used to find out its length. Other than "length;" which is used to get length of an array? give answer to the uniqueness of String.

Answer 1

Arrays are special object in java having attribute length (which is final and is set at time of array definition ) and array are part of language itself so there is no class definition for array which you can find whereas String class has been defined and its definition can be looked into, String class contains a method length() to retrieve String's length.

more detail about array members:-
 Array Members

The members of an array type are all of the following:

The public final field length, which contains the number of components of the array. length may be positive or zero.

The public method clone, which overrides the method of the same name in class Object and throws no checked exceptions. The return type of the clone method of an array type T[] is T[].

A clone of a multidimensional array is shallow, which is to say that it creates only a single new array. Sub arrays are shared.

All the members inherited from class Object; the only method of Object that is not inherited is its clone method.
