Print the number of elements in an array java

Java Program to print the number of elements present in an array

In this example, we will create a java program to count and print the number of elements present in the array.

The number of elements present in a given array can be found by calculating the length of that array.

Algorithm:
  • Step 1: Start
  • Step 2: Initialize arr = {……}
  • Step 3: Print arr.length
  • Step 4: Exit
Program:

public class Main 
{  
public static void main(String[] args) 
{  
int [] arr = new int [] {1, 2, 3, 4, 5, 6, 7, 8, 9};  
System.out.println("Number of elements present in given array: " + arr.length);  
}  
}
  
Output
Number of elements present in given array: 9
