How should you check if a value is null? - Cracking the Java Coding Interview #javacoding #javatips

A quick tip on the best practice for null checking in Java. Instead of using == null, the recommended pattern is Objects.requireNonNull(), which explicitly throws a NullPointerException, returns the checked object for inline use, and accepts a custom error message. An overload also allows returning a default value or using a Supplier for lazy initialization instead of throwing an exception.
