It's neither easy nor trivial and provides some decent practice for a first timer. When I came across CodeAbbey, I really like their question set because it was perfectly designed for beginners. The next site that I am going to share with you guys is CodeAbbey. You can also find a lot of other courses for learning Java from scratch like Practice Java by Building Projects, which is another free course for programmers getting started with Java. Java Tutorial for Complete Beginners, a whopping 767,854 students are enrolled in this course and its one of the best free Java course available online. It also contains a lot of free courses in both Java and other programming languages, e.g. It provides both free and paid courses, but the good part is that you have a lot of choices available and it's relatively cheaper than any other website in the world This is a popular website for learning Java and other languages online.

The second site is language independent because it doesn't ask you to code online, rather it only checks your answers with random input data. The first site is mostly for Java programmers, but the problem set can be solved in any language. In this article, I am going to share with you a couple of websites that will help you learn Java for FREE. Resources for Learning Code in Java Online I highly recommend Introduction to Algorithm though it will not teach you coding, it will give knowledge of data structure and algorithms, which is very important for any programmer. If you are absolutely new to the programming world, then investing money in books on data structures and algorithms is probably a good idea. To be frank, it's not easy to solve problems from those sites until you have really been programming for a year or two, maybe even longer.Ī good way to improve coding is to solve basic data structures, algorithms, and object-oriented design problems by yourself. In 90 percent of cases, programmers simply don't write enough to develop the programming logic and code sense, and if they lack experience dealing with data structures and algorithms and attempt problems are given on sites like TopCoder or Project Euler, they fail miserably.

Like many other things in the world, to improve your coding skills, you need to code, code, and code - and to improve programming, you need to know how to write a program, and that's where many of these programmers fail. These questions are mostly from programmers who just started programming or just graduated with a computer science degree. Being the author of a Java blog, I often receive questions about how to improve my coding skills, the best ways to strengthen my Java skills, or how to solve difficult programming problems.
