The challenge
Create a function that takes an integer as an argument and returns “Even” for even numbers or “Odd” for odd numbers.
The solution in Java code
public class EvenOrOdd {
public static String even_or_odd(int number) {
return number%2==0 ? "Even" : "Odd";
}
}
Test cases to validate our solution
import org.junit.Test;
import static org.junit.Assert.assertEquals;
import org.junit.runners.JUnit4;
public class EvenOrOddTest {
@Test
public void testEvenOrOdd() {
EvenOrOdd eoo = new EvenOrOdd();
assertEquals(eoo.even_or_odd(6), "Even");
assertEquals(eoo.even_or_odd(7), "Odd");
}
}
