A Complete Guide to Java Networking Java Networking refers to the ability of Java programs to communicate over a network, enabling interaction between devices and systems. It provides classes and APIs for developing networked applications, allowing data exchange between client and server applications over various network protocols. In the below PDF we discuss about Networking in […]

Java Regex | Regular Expressions In Java, Regular Expressions or Regex (in short) are sequences of characters that define search patterns. They are used for pattern matching and manipulation of strings. Regular expressions provide a flexible and powerful way to search, replace, and validate text based on specific patterns. Regular expressions in Java are implemented

Java Collection Framework The Java Collection Framework (JCF) is a set of classes and interfaces in the Java programming language that provides a unified architecture for representing and manipulating collections of objects. It was introduced in Java 2, version 1.2, and has since become an integral part of Java development. The primary goal of the

Multithreading in Java Multithreading refers to the concurrent execution of multiple threads within a single process. In Java, a thread represents the smallest unit of execution within a program. By leveraging multithreading, developers can perform multiple tasks simultaneously, thereby maximizing resource utilization and improving application performance. In the below PDF we discuss about Multithreading in Java

File Handling in Java File handling in Java refers to the process of reading from and writing to files on the filesystem using Java programs. It enables Java applications to interact with files, such as reading data from text files, writing data to files, creating new files, deleting files, and more. In the below PDF

Exception Handling in Java An exception is an event that disrupts the normal flow of program execution. Exception handling in Java refers to the process of dealing with unexpected or exceptional situations that occur during the execution of a program. These exceptional situations, known as exceptions, can include errors such as division by zero, file

Packages in Java A package in Java is essentially a namespace that organizes a set of related classes and interfaces. It helps prevent naming conflicts and provides a hierarchical structure to the codebase. Think of packages as directories in a file system, where classes are files stored within these directories. In the below PDF we

Interface in Java In Java, an interface is a reference type, similar to a class, that can contain only constants, method signatures, default methods, static methods, and nested types. However, it cannot contain method implementations or instance variables. Interfaces are used to specify a set of methods that a class must implement. Think of an

Encapsulation in Java Encapsulation can be defined as the bundling of data and methods that operate on the data into a single unit, known as a class. It allows for the hiding of the internal state of an object and restricting access to it from outside the class. In simpler terms, encapsulation enables us to

Inheritance in Java Inheritance is a mechanism in Java that allows a new class to inherit properties and behaviors (methods) from an existing class, known as the superclass or parent class. The class that inherits these properties is called the subclass or child class. This relationship between classes forms an “is-a” hierarchy, where a subclass
