This course is your detailed guide to the fundamentals of the Java programming language. This course will get you on the fast track to becoming a proficient and modern Java developer.

In this course, you will start by covering different programming paradigms like object-oriented and procedural programming. You will then cover the fundamentals of programming in Java such as: objects and data types, variables, arrays, and conditional statements.

In the latter half of the course, you will cover iterative constructs, useful algorithms, and data structures. With over 100 problems, 11 quizzes, and 9 challenges, this course will get you prepared for a career in software development.

A Complete Guide to Java Programming

In the following example, we will try to find the sum of prime divisors. Now, the question is what does this mean? What is the sum of prime divisors? Let’s find out!

To calculate the sum of the divisors of a number, we first do the prime factorization of that number. Then, we take each different prime factor and add together all its powers up to the one that appears in the above process of factorization. Then we multiply these sums together.

Admittedly, this type of problem is a bit tricky and seems weird. However, we try to push the barrier of learning and task you with something that you don’t understand at first. Only then can you learn something new! Everything takes time, this will too.
If you want to rerun the code, write `java main` in the terminal: 

We'll look at different algorithms that help solve problems related to prime numbers.
