write a default constructor for class  Table(in java)  here's the class structure public static int ceiling (double num) {      return num <=0? (int) num : (int) num +1; }

Write the implementation of the Java classes based on the following UML diagram. (a) Define the method IncreTotSpecies) to increment the data field totalSpecles (b) Define the method printColor) to print the data field color (c) Override the method printColor) in the class Falcon to print the data fields featherColor, beakColor Birds +color: String +foodHabit: String +totalSpecies: int -skeleton: String +Birds () +Birds(color: String, foodHabit: String, skeleton: String) +increTotSpecies (): void +printColor (): void Falcon -featherColor: String -beakColor: String +Falcon (featherColor: String, beakColor: String) +printColor (): void

The following is in Java: public class MyClass {       private int x;       private double y;             public static void setValues(int a, double b)       {         x = a;          y = b;       } }   1) What is the problem? 2) In a few sentences how can the issue be fixed?

Can help with this in c++The base class is given Base: class Base { int a;double b;public:Base (int _a, double _b) : a(1), b(2.5) {}Base (int _a, double _b) :a(_a), b (_b) {}double calct () {return 1.5*a+2*b;}string toString(){return "a="+to_string(a) + "b=" + to_string(b);}};Define a class Derived, successor to Base, with an additional field d of type double. For Derived, write constructors, write a new implementation of the calc () method to add to the sum and field d with coefficient 3 and the toString () method, which returns the text description of an object of class Derived.Create objects of class Derived with the written constructors and call the two variants of the methods calc () and toString () (of the class Derived and its base class Base)
