Java Runtime Environment (JRE) JRE is a part of the Java Development Kit (JDK), which is responsible for executing a Java program. It acts as a mediator between the Java program and the OS. This allows the Java program to run on any system that has a compatible JRE installed. JRE contains components like JVM, class libraries, class loaders, and other libraries. Major Components of JRE Java Virtual Machine (JVM) JVM is the main component of the Java Runtime Environment. It performs the execution of the bytecode generated by the compiler and also serves as an interpreter, converting the bytecode ... Read More
In Java, HashSet and TreeSet both belong to the collection framework. HashSet is the implementation of the Set interface, whereas TreeSet implements a sorted set. TreeSet is backed by TreeMap while HashSet is backed by a HashMap. Difference Table The following are the key differences between HashSet and TreeSet − Sr. No. Key ... Read More
In this article, we will learn to print Hello World without a semicolon in C++. The semicolon (;) is used to terminate statements. The above can be achieved by using control structures like loops, conditionals, or function calls. Different Approaches There are multiple ways to write a C++ program without semicolons − Using if Statements Using a while Loop Using Switch Statement Note: Doing this is a very bad practice and should never be used in real code. This is presented just as informational content. ... Read More
In this article, we will learn about the difference between an array and a set in JavaScript. Arrays are used to store ordered collections of elements, whereas in Sets, we can store only unique values. What is an Array? An Array is an ordered, indexed collection of values in JavaScript. It allows duplicate values and provides various built-in methods to manipulate elements. Syntax let numbers= [1, 2, 3, 4, 5]; What is a Set? A Set is an unordered collection of unique values in JavaScript. Unlike arrays, a Set does not allow duplicate values. Syntax let numbers= new Set([1, 2, ... Read More
In this article, we will learn to convert a HashSet to a TreeSet in Java. Converting from one type of collection to another is a simple process when we require them to change their behavior or the nature of our data structure. Why Convert HashSet to TreeSet? For the following operations, we can convert a HashSet to a TreeSet − Sorted Order: TreeSet maintains elements in ascending order. Range-Based Operations: It supports operations like headSet(), tailSet(), and subSet(). NavigableSet Features: TreeSet provides methods like higher(), lower(), ceiling(), ... Read More
In this article, we will implement the linear congruential generator for pseudo random number generation in Java. Pseudo random number generator (PRNG) are mainly used in simulations, cryptography, or mathematical tasks. What is an LCG? A Linear Congruential Generator (LCG) is a technique to generate a sequence of numbers that looks like random numbers but are actually determined. It is one of the reasons to call it a pseudo-random number. The Linear Congruential Generator (LCG) technique generates a random number based on the previous number and uses linear recurrence to generate the sequence of the random number. Mathematical Formula We can ... Read More
The average or mean of an array is a basic mathematical operation in programming. The average is used in analytics, finance, and reporting. One of the real-life applications is a website that calculates the average rating of a product or the average score of a test. In this article, we are going to learn how we can calculate the average of an array of numbers in PHP using different approaches. What is Average? The average is obtained by calculating the sum of all elements in an array and then dividing the sum by the total number of elements ... Read More
JavaScript is a dynamic computer programming language. It is lightweight and most commonly used as a part of the web pages, whose implementation allows a client-side script to interact with a user and to make dynamic pages. It is an interpreted programming language with object-oriented capabilities. Advantages of JavaScript The advantages of using JavaScript are the following − Less server interaction − You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server. Immediate feedback to the ... Read More
