This chapter covered a wide variety of Java operator topics for unary, binary, and ternary operators. Hopefully, most of these operators were review for you. If not, you need to study them in detail. It is important that you understand how to use all of the required Java operators covered in this chapter and know how operator precedence and parentheses influence the way a particular expression is interpreted.

There will likely be numerous questions on the exam that appear to test one thing, such as NIO.2 or exception handling, when in fact the answer is related to the misuse of a particular operator that causes the application to fail to compile. When you see an operator involving numbers on the exam, always check that the appropriate data types are used and that they match each other where applicable.

Operators are used throughout the exam, in nearly every code sample, so the better you understand this chapter, the more prepared you will be for the exam.
