attempting the Review Questions, and good luck!
Exam Essentials
Understand the
if
and
switch
decision control structures.
The
if
and
switch
statements
show up on a lot on the exam. The questions are usually testing your knowledge of some
other aspect of Java, so it is important to be very familiar with
if
and
switch
.
Understand the looping control structures.
Make sure you know the syntax and behavior
of
for
,
while
, and
do
loops, including the enhanced
for
loop. Expect at least one exam
question testing your basic understanding of one of the loops, along with at least one ques-
tion involving nested loops.
Know how to enable assertions.
Assertions are a new concept in Java, and they are
enabled by default. Watch for a question that uses assertions but does not enable them, or a
question that tests your knowledge of how assertions are enabled from the command line.
Understand the flow of control of a
try-catch-finally
block.
Exception handling is an
important concept in Java programming. You need to understand the fl ow of control of all
aspects of a
try-catch-finally
statement, whether or not an exception occurs.
