Step by step
Solved in 2 steps
- True/False: When instantiating an object of an abstract class, you can do it with the keyword new.True or False A static method can reference an instance variable.What is the purpose of a constructor? It creates an array of data values associated with an object. It prints all of the information about our object. It returns all data members from an object back to the main method. It allows us to set our own default values when we create an object. in java
- Object composition is useful for creating an Is-A relationship between classes. is it True or False ??public class Accumulator { private int total private String name; public Accummulator (string name , int total) { this .name = name; this .total=total; } } 3. In a main method, create an object of Accumulator with the name as "Mary" and total as 100.What method is automatically executed whenever a new instance of the class, which the method belongs to, has been instantiated? a. encapsulation b. abstraction c. polymorphism
- Once an object name is declared, can it be reassigned to reference another object?private float c; private void method2(double y) { c = y; } in another class we created an object of the first class then within in it : tester.method2 (10.0f); are there any errors ? how many errors if there are any and with explanation please.class Point { private: int x, y ; public: : x(u), y(v) {} Point (int u, int v) int getX) { return x; } int getY () { return y; } void doubleVal() { *= 2: y *= 2; } }; int main () { const Point myPoint (5, 3) myPoint.doubleVal() ; cout << myPoint.getX() << " " return 0; << myPoint.getY() << "\n"; }
