Consider the following class definitions. public class bclass { private int x; public void set(int a) { x = a; } public void print() { system. out. print(x); } } public class dclass extends bclass { private int y; public void set(int a, int b) { //postcondition: x = a; y = b; } public void print(){ } } which of the following correctly redefines the method print of dclass?
(i) public void print() { system. out. print(x + " " + y); }
(ii) public void print() { super. print(); system. out. print(" " + y); }

Consider the following statements: #include #include class temporary { private: string description; double first; double second; public: temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string& , double& , double& ); void setdescription(string); void setfirst(double); void setsecond(double); }; write the definition of the member function set() so that the instance variables are set according to the parameters. write the definition of the constructor so that it initializes the instance variables using the function set() write the definition of the member function manipulate() that returns a decimal number (double) as follows: if the value of description is "rectangle", it returns first * second if the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. hint: the volume of a cylinder is simply the area of the circle at the base times the height. if the value of description is "sphere" it returns the volume of the sphere with radius first. otherwise it returns -1.0;
