public class MyAssertFalseTest {

	public boolean isEvenNumber(int number){
		
		boolean result = false;
		if(number%2 == 0){
			result = true;
		}
		return result;
	}
	
	@Test

ServletOuptputStream Vs PrintWriter
ServletOutputStream: ServletResponse.getOutputStream() returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data, it sends the raw data as it is.

PrintWriter: ServletResponse.getWriter() returns PrintWriter object which sends character text to the client. The PrintWriter uses the character encoding returned by getCharacterEncoding(). If the response's character encoding has not been specified then it does default character encoding.
