2Write Java Program to check whether a given integer is Even or Odd
3 
4Example 1 : 
5
6  Input  : 27 
7  Output : Odd
8  Explanation :  27 divide by 2 results remainder as 1.

10Example 2 : 
11
12  Input  : 36
13  Output : Even
14  Explanation :  36 divide by 2 results remainder as 0.

Algorithm

1Step 1 : Start 
2Step 2 : Read number "n"
3Step 3 : rem =  n % 2 (Initialize remainder as rem) 
4Step 4 : If rem = 0, print Even 
5Step 5 : Else print Odd. 
6Step 6 : End 

Flowchart

Code Implementation

1import java.util.Scanner;
2
3public class EvenOdd {
4
5  public static void main(String[] args) {
6    Scanner sc = new Scanner(System.in);
7    System.out.println("Enter Number :");
8    int number = sc.nextInt();
9    
10    int rem = number % 2 ;
11    if (rem == 0) {
12      System.out.printf("%d is Even\n", number);
13    }else {
14      System.out.printf("%d is Odd\n", number);
15    }
16  }
17}

Output 1:

1Enter Number : 21
221 is Odd

Output 2:

1Enter Number : 18
218 is Even
