- True or False? Interface can be used to store a common method implementation.Create an interface called Visible that includes two methods:makeVisible and makeInvisible. Both methods should take noparameters and should return a boolean result. Describe how aclass might implement this interface.Describe how overriding a method differs from using an overload of that method.
- Write an accessor method called getName that returns the value of a field called name, whose type is String.IN JAVA LANGUAGE Write an ATM class with an ArrayList of Account objects as an attribute. In the constructor, add 3 Account objects to your ArrayList. They can all have a start balance of $100 and an annual interest rate of 0.12. Include two methods, menu and makeSelection as outlined below. Please note that since both methods get user input, create a Scanner attribute to use in both. menu method This method does not have any parameters and does not return a value. It should: Get the account number from the user. This corresponds to the index of the items in the ArrayList. Since there are 3 elements in your ArrayList, you are going to ask them for a number between 1 and 3, but keep in mind that the indices of the ArrayList are 0-2, so you'll have to adjust the value you get from the user accordingly. Present the user with a main menu as shown below: Get their menu selection Call the makeSelection method, passing it the account index obtained in step 1 and the menu selection…What is included in the method private void buildLetterTable() { implemented in the class Anagrams
- Write a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.please help me understand this code in java (using generic method). More specifically why was item1,item2, item3 parameter names never used again and what is the purpose of this line of code: TheType tripleMin(TheType item1, TheType item2, TheType item3) {Apply & Create method overloading and method overriding in your own guide book
- All generic method declarations have a type-parameter section that immediately precedes the method name. State whether the statement is true or false. If false, explainwhy.The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();}Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper limit.…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 :…
