To implement an interface, a concrete class must implement AT LEAST ONE method heading.
False.
True.
Step by step
Solved in 2 steps
- To implement an interface, a concrete class must implement AT LEAST ONE method headings listed in the definition of the interface. False. True.To implement an interface, a concrete class must implement AT LEAST ONE method headings listed in the definition of the interface.Create a Visible interface with two methods: makeVisible and makeInvisible. Both methods should accept no parameters and return a boolean value. Explain how a class may implement this interface.
- To implement an interface, a concrete class must implement AT LEAST ONE method heading.Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle. (Note: Concrete classes don’t have any abstract method)
- When a class implements an interface with default methods and overrides them, the class inherits the default methods’ implementations. An interface’s designer can now evolve an interface by adding new default and static methods without breaking existing code that implements the interface. State whether the statement is true or false. If false, explain why.Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classesTrue or False An interface can contain only abstract methods and constants.
- Create a new class called AdvancedMath that implementmyMath interface, which have following methods like sqr(),round(), floor(). These methods have to be implemented byAdvancedMath class.Java - Interface 1. Create an interface Employee which has the attribute: rate, and the method getSalary(). 2. Implement the Employee interface with two classes: Hourly and Commissioned. 3. Hourly employee has the following additional attribute: hoursWorked. Hourly wage is 300 money. 4. Commissioned employee has the following additional attribute: itemSold. Commissioned employees get 200 money per item sold. If item sold is greater than 100, any items sold after 100 has +10 money bonus. Inputs 1. First line contains the type of Employee (H or C) 2. Second line is for the hours worked or the items sold depending on the type of employee Sample Output Enter type of employee: H Enter hours worked: 10 Salary: 3000An interface is a collection of _______ that a class can implement
