Certification Objective: Common Exceptions and Errors (Exam Objective 2.6)

2.6 Recognize situations that will result in any of the following being thrown: ArrayIndexOutOfBoundsException, ClassCastException, IllegalArgumentException, IllegalStateException, NullPointerException, NumberFormatException, AssertionError, ExceptionInInitializerError, StackOverflowError, or NoClassDefFoundError. Understand which of these are thrown by the virtual machine and recognize situations in which others should be thrown programmatically.

Exception handling is another area that the exam creation team decided to expand for the SCJP 5 exam. This section discusses the aspects of exceptions that were added for this new version. The intention of Objective 2.6 is to make sure that you are familiar with some of the most common exceptions and errors you’ll encounter as a Java programmer.
