public class MyAssertFalseTest {

	public boolean isEvenNumber(int number){
		
		boolean result = false;
		if(number%2 == 0){
			result = true;
		}
		return result;
	}
	
	@Test
	public void evenNumberTest(){
		MyAssertFalseTest asft = new MyAssertFalseTest();
		assertFalse(asft.isEvenNumber(3));
	}
}

What is wrapper class?
Everything in java is an object, except primitives. Primitives are int, short, long, boolean, etc. Since they are not objects, they cannot return as objects, and collection of objects. To support this, java provides wrapper classes to move primitives to objects. Some of the wrapper classes are Integer, Long, Boolean, etc.
Famous Quotations
