Complete Java SE 8 Developer Bootcamp - Predicate

The video tutorial explains the concept of the predicate interface introduced in Java 8, which is used to run tests on objects and return a Boolean result. It covers the parameter type T in generics, demonstrating how predicates can be used in methods to determine if a customer should be included in a promotional mailing. The tutorial also shows how lambda expressions can be used to pass tests to the predicate, with an example of checking if a customer's age is over 18.
