Understanding Parameterized Functions in Java

Understanding Parameterized Functions in Java

Comments 4 Comments

In this tutorial, we will explore the concept of parameterized functions in a class by using a simple example of a Calculator class. This will help in understanding how to pass values (parameters) to a class and its methods, manage attributes, and perform operations such as addition, subtraction, and multiplication. We will walk through the code step by step to understand its structure and working. You can visit the detailed tutorial here. What is a Parameterized Function? A parameterized function…

In Java, a constructor is a special type of method that is used to initialize objects. It is called when an instance of a class is created. The main purpose of a constructor is to set initial values for the object’s fields (variables). Think of it as a way of setting up your object when it is first created, similar to preparing a car before driving it. Key Features of a Constructor Why Use a Constructor? Imagine you want to…

A class is a blueprint or a template for creating objects. It defines the properties (attributes) and behaviors (methods) that an object of that class will have. Think of a blueprint for a house. The blueprint defines the layout, number of rooms, and overall structure of the house. When you build houses based on this blueprint, each house will have the same layout and structure. In programming, a class is like a blueprint for objects. It defines the properties and…

Object-Oriented Programming (OOP) is a programming paradigm that models real-world entities as objects. These objects have properties (attributes) and behaviors (methods). OOP emphasizes the concept of encapsulation, inheritance, and polymorphism. Why Use Object-Oriented Programming (OOP)? OOP offers several significant advantages that make it a popular programming paradigm: Reusability: One of the core benefits of OOP is code reusability. Through inheritance, new classes can be created based on existing ones, inheriting their properties and methods. This means that you can reuse…
