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

Length of above array is 5. Hence, the number of elements present in the array is 5.

Algorithm

STEP 1: START
STEP 2: INITIALIZE arr = {1,2,3,4,5}
STEP 3: PRINT arr.length
STEP 4: EXIT

Program:

public class CountArray {
    public static void main(String[] args) {
      //Initialize array
        int [] arr = new int [] {1, 2, 3, 4, 5};
      //Number of elements present in an array can be found using the length
        System.out.println("Number of elements present in given array: " + arr.length);
    }
}

Output:

Number of elements present in given array: 5
