Java Program to Print Length of an Array
import java.util.*;
public class Main
{
public static void main(String[] args) {
int arr[] = {2,4,6,8,9,4};
System.out.println("Java Program to calculate length of array ");
System.out.println("The size of the array arr is = "+ arr.length);
}
}
Output
Java Program to calculate length of array
The size of the array arr is = 6
