How to calculate the array length in Java?

Question

Can anybody tell me how to calculate the array length?

Answer 1

Array length is nothing but the number of elements present in an array. There is no already defined method in java that can give the length of an array. But the array length can be found by using array attribute length. 

Every array has an already defined length property whose value is the size of the array. Size is nothing but the total number of elements present in an array. Length property can be invoked by using the dot (.) operator further followed by the array name.

 

Code: 

public class ArrayLengthCode   

{   

public static void main(String[] args)   

{   

//initializing an string type array named country   

String[] country = { "India", "France", "Spain", "USA", "UAE", "Germany", "Brazil"};  

//length is an Array attribute that determines the array length   

int arrayLength=country.length;   

//prints length of an array  

System.out.println("The size of the array is: " + arrayLength);   

}   

}
