In Java programming, arrays are a powerful tool for storing and manipulating collections of data. However, arrays have a fixed size, which can be limiting in some cases. To work with collections of data that can grow or shrink dynamically, Java provides three built-in classes: ArrayList, LinkedList, and Vector. In this blog post, we will … Read More “Java | Working with ArrayLists, LinkedLists, and Vectors” »
Java provides a powerful set of classes and interfaces that collectively make up the Java Collections Framework. This framework is designed to provide a standard way of working with collections of objects in Java, and offers a number of advantages over traditional arrays. In this blog post, we will introduce the basic concepts of collections … Read More “Java | Introduction to collections (List, Set, Map)” »
An array is a collection of similar data items that are stored in a contiguous memory location. In Java, arrays are used to store multiple values of the same data type. Declaring and Initializing Arrays: To declare an array in Java, you need to specify the data type of the array elements, followed by the … Read More “Java | arrays and its methods” »
Loops are an essential part of any programming language, including Java. In this blog post, we will discuss three types of loops available in Java, namely while, do-while, and for loops, along with example code and commands. int i = 0; while (i < 5) { System.out.println(i); i++; } This code will print out the … Read More “Java | Loops (while, do-while, and for)” »
In this blog post, we will be discussing an important topic in Java programming, namely “Conditional statements (if-else and switch)”. Conditional statements are used to execute specific blocks of code based on certain conditions. In Java, there are two types of conditional statements: the if-else statement and the switch statement. if-else statement The if-else statement … Read More “Java | Conditional statements (if-else and switch)” »
In this blog post, we will be discussing another important topic in Java programming, namely “Reference data types in Java”. Reference data types are used to store complex and non-primitive types of data, such as objects, arrays, and strings. These data types are also known as non-primitive data types, because they are not built into … Read More “Reference data types in Java” »
