Talking: Heba Abde QUESTION 1: Implement class myTime, this class should: 1) Encapsulate information about the hours (integer), minutes (integer), seconds (integer), AM PM (String) 2) Forbid invalid times, where the following criteria should be considered: - hours are in the range [1 – 12], default is 12. - minutes are in the range [0 – 59], default is 0. - seconds are in the range [0-59], default is 0. - AM PM can only be either “AM" or "PM", default is "AM" If any forbidden value entered, you should set the value to default value. 3) Two different constructors (default and parameterized) 4) A print function that will print the time as (hours : minutes : seconds PM/AM) Example: 02:45:30 PM 6) implement function ticktack, which adds one to the seconds, notice that if seconds is 59 and you add one, it should become 0 and the minutes should be incremented by one, also, if after incrementing minutes by one it becomes 60, it should be set to 0 and hours must be incremented by 1, if after…

Activity: Create a collection of objects using Java generics. use java to write code. Create a Month class that can accept integer or String data type as an argument. The parameter type will be decided at run time. For this exercise, we will use Month class to store integer and string values that contains 12 months. For example, the integer value of 12 corresponds to string value of “December.” Use the following minimal class definition for Month class. public class Month<T> { private T month; public void setMonth(T month); public T getMonth(); }; Create a new class, MonthApp. This new class will have main method, and will instantiate Month objects to store month indices and names. Here is an example using arrays. // defineMonth<Integer>[] monthsByNumber = new Month<>[12];Month<String>[] monthsByName = new Month<>[12];// adding valuesmonthsByNumber[0] = new Month<Integer>();monthsByNumber[0].setMonth(1);monthsByName[0] = new…

class A{ int a; int b; } class B extends A{ int a; public static void main(String[] args){ B obj=new B(); } } How do you get access to the variable "a" in class A? use obj.a use obj.super.a create an object of type A and then reference the variable O both b and c
True or False: "this" is a reference to the current object in an instance method or function Object() { [native code] }.
class A Q5: Correct the following code fragment and what will be the final results of the variable a and b { protected int x1,y1,z; public: A(a, b,c):x1(a+2),y1(b-1),z(c+2) { for(i=0; i<5;i++) x1++; y1++;z++;}}; class B { protected: int x,y; public: B(a,b):x(a+1),y(b+2) { for(i=0; i<5;i++) x+=2; y+=1;}}; class D:public B, virtual public A { private: int a,b; public: D(k,m,n): a(k+n), B(k,m),b(n+2),A(k,m,n) { a=a+1;b=b+1;}}; int main() {D ob(4,2,5);}
1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { using namespace std; IntegerArray a(2); a.data[0] = 4; class IntegerArray { public: a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; solve number 2 } -IntegerArray()) { delete[] data;…
JAVA Language Caesar Shift Question: Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3.
