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:

- In Kotlin, Write a Circle data class, with a radius as a parameter to the constructor, a custom-coded property for the area, and a sizeRatio() function that takes a reference to another Circle and returns the ratio of the radius of the instance circle (the one you call the function on) to the other circle . Use math.pow and math.PI. Write a main() that creates a circle, prints it (which will print it's automatically generated toString()), prints its radius, creates another circle, and shows the size ratio of the two.a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).in java Create a class for Student and implement all the below listed concepts in your class.

- IN JAVA LANGUAGE Write an ATM class with an ArrayList of Account objects as an attribute. In the constructor, add 3 Account objects to your ArrayList. They can all have a start balance of $100 and an annual interest rate of 0.12. Include two methods, menu and makeSelection as outlined below. Please note that since both methods get user input, create a Scanner attribute to use in both. menu method This method does not have any parameters and does not return a value. It should: Get the account number from the user. This corresponds to the index of the items in the ArrayList. Since there are 3 elements in your ArrayList, you are going to ask them for a number between 1 and 3, but keep in mind that the indices of the ArrayList are 0-2, so you'll have to adjust the value you get from the user accordingly. Present the user with a main menu as shown below: Get their menu selection Call the makeSelection method, passing it the account index obtained in step 1 and the menu selection…tri1 and tri2 are instances of the Triangle class. Attributes height and base of both tri1 and tri2 are read from input.

- You are required to build a class JewelleryItem. A jewellery Item has a type (string) , price (float),material (string), daysToGo (int).These attributes represent the type i.e ‘ear ring’, necklace, finger ring etc. The material can be gold,silver, plastic etc. The daysToGo attribute represents the number of days it will remain fit for use.1. You are required to provide the following parameterized constructors JewelleryItem(string type, float price, string material, int daysToGo) Jewlleryitem(string type, float price, int daysToGo) // the material will get “gold” as default JewelleryItem(string type, float price) //the material defaults to gold and daysToGo defaults to100.2. Now provide getters for each of the attributes above but setters for only price, daysToGo3. Provide a function/method makeUse(). This function represents the use of this item for one daywhich reduces the daysToGo by 1. This function returns true if the daysToGo is greater than 1 andfalse otherwise. This means…This is the question I am struggling on - Create a TeeShirt class for Toby’s Tee Shirt Company.
