Exercise (Method): boolean method called isOdd() in a class called OddTest, which takes an int as input and returns true if the it is odd. The signature of the method is as follows:

public static boolean isOdd(int number)

Also write the main() method that prompts user for a number, and prints "ODD" or "EVEN". You should test for negative input.

Answer:

import java.util.Scanner;

public class OddTest {

  public static void main(String[] args) {

    // TODO code application logic here

    Integer number; //for storing input

    boolean result; //for storing the return value of IsOdd function

    Scanner scInput = new Scanner(System.in);

    System.out.print("Please enter a number: ");

    number = scInput.nextInt();

    result = isOdd(number);

    if (result) {

      System.out.println("The number is: ODD");

    }

    else

    {

      System.out.println("The number is: EVEN");

    }

    }

  //return true if the number is odd otherwise return false

  static boolean isOdd(Integer number){

    number = Math.abs(number); //make the absolute value

    return number%2 != 0; //check for even(divisible by 2)

  }

}
