Java streams are an important feature of the Java language that allow you to read from and write to files and other input/output (I/O) devices. Streams are a powerful and efficient way to handle I/O operations in Java, and they provide a number of benefits over traditional I/O methods. In this article, we’ll discuss how … Read More “Java | Using Java streams for I/O operations” »
Reading and writing data from/to files is a common task in programming. In Java, you can read and write data from/to files using the java.io package. In this article, we will explore how to read and write data from/to files in Java with examples. Reading data from files To read data from a file, you … Read More “Java | Reading and writing data from/to files” »
Java provides a mechanism for handling errors and exceptional situations called exceptions. An exception is an object that describes an error or an abnormal condition that has occurred during program execution. Exceptions can occur for various reasons, such as incorrect input, network problems, or system errors. Java also provides a way to handle these exceptions … Read More “Java | Throwing and propagating exceptions” »
In Java, an exception is an event that occurs during the execution of a program and disrupts the normal flow of instructions. When an exception is thrown, it can be caught and handled by the program, or it can propagate up the call stack until it reaches the top level of the program, at which … Read More “Java | Understanding the concept of exceptions” »
Inheritance is a key feature of object-oriented programming, which allows a class to inherit properties and behaviors from another class. In Java, inheritance is implemented using the extends keyword, which allows a subclass to inherit properties and methods from a superclass. This helps in reducing code duplication and makes it easier to create and maintain … Read More “Inheritance in java” »
In Java programming, constructors and static methods are two important concepts that are used to create and initialize objects, and to perform operations that are not related to any specific instance of a class. In this article, we will explore these concepts in more detail, with examples of how to use them. Constructors In Java, … Read More “Java | Constructors and static methods” »
Java is an object-oriented programming language, which means that it is based on the concept of classes and objects. Classes are the blueprint for creating objects, and objects are the instances of classes. In this article, we will discuss how to create classes and objects in Java. Creating a Class in Java A class is … Read More “Java | Creating classes and objects in Java” »
Java is a popular programming language that is used to build a variety of applications, from web-based applications to mobile apps. One of the reasons for its popularity is that it is an object-oriented programming (OOP) language. In this article, we will introduce the basic OOP concepts in Java, including classes, objects, methods, encapsulation, inheritance, … Read More “Java | Introduction to OOP concepts (classes, objects, methods, encapsulation, inheritance, and polymorphism)” »
In Java programming, a set is a collection of distinct elements, i.e., it cannot contain duplicate values. Java provides three built-in classes for working with sets: HashSet, LinkedHashSet, and TreeSet. In this blog post, we will explore these classes in detail, including their similarities and differences, and provide examples of how to use them in … Read More “Java | Working with Sets (HashSet, LinkedHashSet, and TreeSet) and Maps (HashMap, LinkedHashMap, and TreeMap)” »
In Java programming, collections are an important part of any Java program. They allow us to store and manipulate groups of related data in a way that is easy to work with. To access and manipulate the data in these collections, we need to be able to iterate over the contents of the collection. There … Read More “Java | Iterating through collections using loops and iterators” »
