In this tutorial, we will learn to write a Java program to create an array and print the even elements stored in the array. Our program will first enter the size of the array and then the elements of the array. Then it will print all the even numbers from the elements of the input array.
For example
Case 1: If the user enters 4 as the array size and the array elements as 1,2,3,4, the output should be 2, 4.
Case 2: If the user enters 5 as the array size and the array elements as 9, 8, 7, 6, 5, the output should be 8, 6.
Print All Even Numbers in Array
import java.util.*;
public class ArrayExample {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Java Program to print all even numbers in array ");
System.out.print("Enter the size of array: ");
int size = sc.nextInt();
int arr[] = new int[size];
for (int i = 0; i < size; i++) {
System.out.print("Please give value for index " + i + " : ");
arr[i] = sc.nextInt();
}
System.out.println("Even number in array are");
for (int i = 0; i < size; i++) {
if (arr[i] % 2 == 0) {
System.out.print(arr[i] + "\t");
}
}
}
}
Explanation
For the input array [1, 2, 3, 4, 5] , iterating the elements of the array. For the elements 2 and 4, the if condition is satisfied and then the numbers 2 and 4 are printed as output of the program.
Output
Java Program to print all even numbers in array
Enter the size of array: 5
Please give value for index 0 : 1
Please give value for index 1 : 2
Please give value for index 2 : 3
Please give value for index 3 : 4
Please give value for index 4 : 5
Even number in array are
2 4
