Sum of n Natural Numbers in Java (using for loop)

Java, one of the most widely used programming languages, offers a powerful and versatile platform for performing various mathematical operations, including finding the sum of n natural numbers.&nbsp;
Whether you are a beginner looking to grasp the fundamentals of Java programming or an experienced developer seeking to streamline your mathematical computations, understanding how to calculate the sum of natural numbers in Java is a fundamental skill.
<h2 dir="ltr">Meaning of Natural Numbers</h2>
In mathematics, natural numbers are the positive integers starting from 1 and extending indefinitely (1, 2, 3, 4, ...). The task of finding the sum of the first n natural numbers involves adding all the numbers from 1 to n. This operation is not only important in mathematics but also finds numerous applications in computer science and real-world scenarios.
<h2 dir="ltr">Use Cases and Significance</h2>
1. Mathematics: Understanding how to sum natural numbers is a fundamental concept in number theory and arithmetic. It forms the basis for more complex mathematical operations and is often used to derive formulas for mathematical series.
2. Programming: In computer science and programming, calculating the sum of natural numbers is a common task. It is useful in various algorithms, such as calculating averages, finding the factorial of a number, and solving mathematical puzzles.
3. Finance: In the financial world, the sum of natural numbers can be applied to calculate the future value of investments, interest rates, and annuities.
4. Data Analysis: When dealing with data, particularly in statistics, finding the sum of a series of numbers is essential for calculating various statistics, including the mean and variance.
5. Project Management: In project management, summing natural numbers can be used for resource allocation, cost estimation, and project planning.
In this tutorial, we will learn the different approaches to finding the sum of n natural numbers in Java. Let's get started!
