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 string.
For example :
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 array.

For example :
String days[]={“Sun”,”Mon”,”Tue”,”Wed”,”Thu”,”Fri”,”Sat”};
Will return 6 since the number of values in days array is 7.
