The predicate in java is a savior to the programmers for making and creating codes in more clean and readable formats. It helps in making the test cases formatting better and enhances the test cases. In general terms, Predicate is just a statement in a Boolean format that helps evaluate cond...

Java 8 predicate negate() returns a predicate that is the logical negation of this predicate. Java 11 introduced not() which is also the same.
