Why should one use Objects.requireNonNull()?

Question

I have noted that many Java 8 methods in Oracle JDK use Objects.requireNonNull(), which internally throws NullPointerException if the given object

Answer 1

Null pointer exception is thrown when you access a member of an object which is null at a later point. Objects.requireNonNull() immediately checks the value and throws exception instantly without moving forward and making it easier to detect where the null exception actually occured.
