Although you might not immediately know the correct answer to a question, if you can reduce the question from five answers to three, your odds of guessing the correct answer are markedly improved. Moreover, if you can reduce a question from four answers to two, you'll double your chances of guessing the correct answer!

In some cases, you may be able to eliminate answer choices without even reading the question. If you come across such questions on the exam, consider it a gift. Can you correctly answer the following question in which the application code has been left out?

1 Which line, when inserted independently at line m1, allows the code to compile?- Code Omitted -public abstract final int swim();public abstract void swim();public abstract swim();public abstract void swim() {}public void swim() {}

Without reading the code or knowing what line m1 is, we can eliminate three of the five answer choices. Options A, C, and D contain invalid declarations, leaving us with options B and E as the only possible correct answers.

In previous versions of the exam, the test-taking software allowed you to eliminate an option by right-clicking on it. The option was then presented with a strike-through line over it. Unfortunately, Oracle no longer offers this feature, so you'll need to use provided writing material to keep track of option choices. Hopefully, Oracle will bring back this feature with an update!
