How to Find Java Array Length


java array length Java Array Length 


We can find the length of an array by using length variable.


1. length  variable:-


length is a final variable applicable only for arrays.


length variable represents the size of an array.


 example:


                                   int [ ] x = new int [6]; 


 System.out.println(x.length);    o/p    is  6 .


                                int [ ] x =new int [10];


System.out.println(x.length);    o/p    is  10 .


System.out.println(x.length());  


Compile-Time Error:cannot find symbol
Symbol: method length()
location: class int [ ]

But Do not Apply length( ) method here.Because length( ) is applicable for String.


2.length (  ) method:-


length( ) is a final method appicable for String Objects/


length( ) return the numbers of character present in the String.  


example:


String s="javabychetan";


System.out.println(s.length());   o/p is     12 


System.out.println(s.length);  


                                             Compile-Time Error: cannot find symbol

                                                    Symbol: variable length

                                                     location: class java.lang.String
