public class MyAssertTrueTest {

	public boolean isEvenNumber(int number){
		
		boolean result = false;
		if(number%2 == 0){
			result = true;
		}
		return result;
	}
	
	@Test
	public void evenNumberTest(){
		MyAssertTrueTest asft = new MyAssertTrueTest();
		assertTrue(asft.isEvenNumber(4));
	}
}

Knowledge Centre
String Vs StringBuffer
We know that String is immutable object. We can not change the value of a String object once it is initiated. If we try to change the value of the existing String object then it creates new object rather than changing the value of the existing object. So incase, we are going to do more modificatios on String, then use StringBuffer. StringBuffer updates the existing objects value, rather creating new object.
