We define the distinction between "static" and "dynamic" binding (i.e., between virtual and nonvirtual methods).
write a program to implement the above interface using Lambda Expression to accept “ Hello World” and print it 10 times. write a program to implement the above interface using Inner Class to accept “ Hello World” and print it 10 times This is my code interface interf1 { publicvoidrepeat(Strings1); } public class Main { public static void main(String[] args) { interf1 obj = (s1)-> { //using lambda expression for(int i=0;i<10;i++) { System.out.println(s1); } }; obj.repeat("Hello World"); } } public class Assignment { public static void main(String[] args) { interf1 obj = new interf1() { //inner class public void repeat(String s1){ for(int i=0;i<10;i++){ System.out.println(s1); } } }; obj.repeat("Hello World"); //function call } } But i keep getting this error Exception in thread "main" java.lang.NoClassDefFoundError:…

A generic class is defined below. Complete the program as told by the comments. public class Example { private T1 number; private T2 description; I -- define the method setExampleData() to set both variables- public void setExampleData (T1 n, T2 d){ [1] [2] } public static void main( [3] ) { // arguments create an object obj1 by parameters Integer and String- --- [4] -call the setExampleData() method-- [5] } }
1. Consider the header of this class: public class AList implements iList Which type of class is AList? (A. Interface class, B. Derived class, C. Base class, D. Generic Class)
Java provides one interface to sort objects of user defined types. What is the name of this interface type. Use an example to describe how to implement this interface.
We have a parking office class for a parking management system. It has dependencies and relations with customer, car, parking lot and parking charge classes. Explain the code by stating implementation decisions, reasons behind those implementation decisions, what you assume was hard or easy to implement, and what helped. public class ParkingOffice {String name;String address;String phone;List<Customer> customers;List<Car> cars;List<ParkingLot> lots;List<ParkingCharge> charges; public ParkingOffice(){customers = new ArrayList<>();cars = new ArrayList<>();lots = new ArrayList<>();charges = new ArrayList<>();}public Customer register() {Customer cust = new Customer(name,address,phone);customers.add(cust);return cust;}public Car register(Customer c,String licence, CarType t) {Car car = new Car(c,licence,t);cars.add(car);return car;}public Customer getCustomer(String name) {for(Customer cust :…
6.b.Fast in java coding please. Thank you 1. Abstract classes and interfaces can both be used to model common features.How do you decide whether to use an interface or a class?2. What is Garbage Collection and how can you mark an object for GarbageCollection.
Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method score() of the parent class to calculate the weighted score for both types of students. Write a driver class JavaProgramming.java which has the main method. Create one remote student object and one in-person student object. The output should show prompts to enter individual scores – midterm, finals, ...... etc. and the program will…
