Encapsulation is one of the four fundamental concepts of object-oriented programming (OOP), alongside inheritance, polymorphism, and abstraction. Encapsulation in Java refers to the bundling of data (fields) and the methods that operate on the data…
Abstraction is a key concept in object-oriented programming (OOP) that hides the complexity of the system by exposing only the relevant information and functionality to the user. It allows focusing on what an object does…
Aggregation is a key concept in object-oriented programming (OOP) that represents a “has-a” relationship between two classes. In Java, aggregation allows one class to be a part of another class, but both classes maintain their…
Inheritance is one of the fundamental concepts of object-oriented programming (OOP) in Java. It allows a new class to acquire the properties and behavior (fields and methods) of an existing class. The existing class is…
Polymorphism is one of the four pillars of object-oriented programming (OOP), along with encapsulation, inheritance, and abstraction. Polymorphism allows objects of different classes to be treated as objects of a common super class. It enables…
Java bitwise operators allow you to manipulate individual bits of integer types (such as int, short, byte, and long). These operators are less commonly used than arithmetic and relational operators, but they are crucial in…
Relational operators in Java are used to compare two values and determine the relationship between them. They are also called comparison operators because they compare operands and return a boolean value: true or false. Understanding…
Arithmetic operators are essential for performing mathematical calculations in Java. Java provides several arithmetic operators to manipulate data values, including addition, subtraction, multiplication, division, and more. Understanding how to use these operators effectively is a…
