OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Implement the design of the Patient class so that the following output is produced:[For BMI, the formula is BMI = weight/height^2, where weight is in kg and height inmeters] Driver Code # Write your code herep1 = Patient("A", 55, 63.0, 158.0)p1.printDetails()print("====================")p2 = Patient("B", 53, 61.0, 149.0)p2.printDetails() OutputThe Problem: You have a function that is called repeatedly to compute thesame values. This function is taking a long time to do its job. How can you makethings faster?Let's take a look at an example. Below is a rectangle class. Thefunction compute_serial returns a unique serial string which is used forsorting the shapes classes.class rectangle { private: int color; int width; int height; rectangle(int i_color, int i_width, int i_height): color(i_color), width(i_width), height(i_height) {} void set_color(int the_color) { color = the_color; } char serial_string[100]; // Unique ID string char* get_serial() { snprintf(serial_string, sizeof(serial_string), “rect-%d x %d / %d”, width, height, color); return (serial_string); }Examination of this class shows that it uses the snprintf to compute the serial string. This is an extremely costly function to use. We need optimize out this function if at all possible.

- in Java language : Write a program to print the area of a rectangle by creating a class named “Rectangle” with constructor having the two sides (width and height) as its parameters Test the class by creating a main class which contains the main method -->name the class “TestRectangle” Use the Scanner library to take the two sides as inputs from the console.Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation.

A Baby has a name of type String and an ageof type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supplymethods for setting the name, setting the age, getting the name and getting theage.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values fromthe instance variables must be done with get methods. The set method for thename instance variable should ensure that the input is not empty or containwhitespaces (otherwise set a default value).

- Write a program in the Java language requires the management of university students, where student data (name, student number, and specialization) are saved, and then he can add and delete study materials for the current semester, and you can also add the grade for each subject (with the addition of the final code for the degree automatically).Note: The class principle is used to solve this assignment.Implement the FindText() function, which has two strings as parameters. The first parameter is the text to be found in the user provided sample text, and the second parameter is the user provided sample text. The function returns the number of instances a word or phrase is found in the string. In the PrintMenu() function, prompt the user for a word or phrase to be found and then call FindText() in the PrintMenu() function. Before the prompt, call cin.ignore() to allow the user to input a new string.Ex: Enter a word or phrase to be found: more "more" instances: 5class Param3 { public int x; private void increase(int p) { x = x*p; } public void calculateX(int y) { increase(y); } public int getX() { return x; } } // in another class Param3 q3 = new Param3(); q3.x = 5; q3.calculateX(7); System.out.println(q3.getX()); what would be the answer for the last two lines ? also above were x = x*p do both x in here are the fields? wouldn't that be cnofusing?
