Predicate和Consumer接口– Java 8中java.util.function包下的接口java
public static Student updateStudentFee(Student student, Predicate<Student> predicate, express
Consumer<Student> consumer){ide
//Use the predicate to decide when to update the discount.spa
if ( predicate.test(student)){code
consumer.accept(student);orm
return student;
}
}
public static void main(String[] args) {
Student student1 = new Student("Ashok","Kumar", 9.5);
tudent1 = updateStudentFee(student1,
//Lambda expression for Predicate interface
student -> student.grade > 8.5,
//Lambda expression for Consumer inerface
student -> student.feeDiscount = 30.0);
