In this tutorial, we will learn writing java program to create an array and print the length of the array. Our program will return the size of the given array.
For example
Case 1: if the given the array is {1, 2, 3, 4}.
The output should be 4.
Case 2: if the given array is {9, 8, 7, 6, 5}.
The output should be 5.
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 = 6Explanation
For the given array {2, 4, 6, 8, 9, 4}, the arr.length() function will calculates the length of the array, the arr.length() function will return the length of array in ‘int’ data type.
