Title: Method call and Array declarations - Exam
questions tests - Sun
Java Programmer 310-065 - Lesson 69
Duration: 18 minutes
In this video, we continue our second set of the Java certification exam. We
start with a class that tests our ability to follow method calls. One method
calls another with appropriate parameter and casting. We need to follow the
correct method call and produce the right output. With these type of questions,
it is important to draw the method calls on a piece of paper so you can track
it back when the call stack unwinds. In
the second question we talk about array declarations, how arrays get passed
into methods, and how their values get changed. The third question is about
working with regular expressions. Remember that \d matches a digit, \s matches
a space, and \w matches a word. The method start() returns the starting
position of a match, and the method group() returns the group that was matched.
In the fourth question, we look at the correct way of getting a Date() object
from a calendar class (using the getTime() method of the Calendar class).
