Checked and unchecked exceptions each have their own advantages and disadvantages, so the decision about which to use largely depends on the situation and context.

Java doesn’t force you to catch or handle these because they indicate abnormal, unexpected problems with your code such as NullPointerException, ArithmeticException and IndexOutOfBoundsException. Our developer communicates with me every day, and is a very powerful coder.

One of the most common and effective techniques for avoiding these issues is to use meaningful, non-null defaults. In other words, simply avoid using null to the extent that you can. Avoid setting variables to null and avoid returning null from methods whenever possible (e.g., return an empty list rather than null). When calling a method that throws exceptions, the caller must either handle (i.e., catch) those exceptions or must throw them itself. Abstract classes are useful for defining abstract template methods that concrete subclasses must implement. All concrete subclasses are therefore guaranteed to honor the API specified by the abstract methods in the abstract class they inherit from.
One of the best ways to evaluate a Java developer’s experience is to look at their past work. Check their portfolio, see the projects they have worked on, and assess the quality of their code.
