Q: What is difference between length and length() method in java ?

length() : In String class we have length() method which is used to return the number of characters in


Ex : String str = “Hello World”;


Str.length() will return 11 characters including space.

length : we have length instance variable in arrays which will return the number of values or objects in


For example :

String days[]={” Sun”,”Mon”,”wed”,”thu”,”fri”,”sat”};

Will return 6 since the number of values in days array is 6.
