Learn By Doing: Learn to Code by Coding Exercises and Projects
This free Java video course teaches skills, not just theory. Each course section comes with carefully prepared hand-on practical exercises, where you write code to solve practical problems, run and test your solutions, maybe make bugs, fix them, and test your code over and over until it finally works properly. The entire course provides more than 70 exercises, with automated grading in the SoftUni judge system.
Remember that coding is a skill, and it should be practiced, just like any other skill. Write code to learn the skill of coding!
Automated Grading System for Your Code
To check your solutions of the practical hands-on exercises from this course, I give you a free access to the SoftUni’s automated judge system, where you send your Java code, and you get automated grading: the judge tells you whether your solution is correct or wrong. This is quite useful. Try it and you will love it!
During the course lessons I will show you how to solve many coding problems. Follow my guidelines and sample solutions and write your own solutions. Try to solve the additional exercise problems as well. Write code, play with the code, experiment, make bugs and imperfections, fix them, write code, do it many times! This is how you acquire coding skills.
Spend Enough Time on the Exercises!
Don’t skip the coding exercises at the end of each course section! They are much more important than the video lessons. The exercises give you the practical skills, the skills needed for your next tech job.
If you are serious about programming, take this course with all its exercises. You should invest about 30 or maybe 40 hours. Yes, this is a lot of time, but learning programming takes time! Just like learning math. Did you remember how many hours you spent at school to learn the basics of math?
In case you have a question or difficulty solving some of the exercise problems, or you have a bug, and you don’t know how to fix it, we are here to help. Join the SoftUni community and ask our coding mentors for free anything about coding and particularly about this course and its practical exercises.
This Java Course is Just a Start
This course is just a start in Java programming. To become a software engineer and start a tech job, you should learn and practice programming 10-15 times more than what I give you in this course. It takes time and effort to build the skills for your first IT job, so be patient and keep coding for long time (1-2 years until your first developer job).
If someone says that a beginner can learn programming and start a job in 3 or 5 months, don’t believe him. This is unlikely to happen. You better study slowly and thoroughly. The effort will pay off.

The Judge System: Automatic Grading for Your Code
Before the start, I will show you the SoftUni judge system, where you can check your exercise solutions instantly, for free.
SoftUni Judge is an automated system for code evaluation. Just send your code solution for certain coding problem from this course and the system will tell you whether your solution is correct or not and what exactly is missing or wrong. I am sure you will love the judge system, once you start using it!
Java Coding: First Steps
This section is the beginning of our journey with Java coding. I will explain you what Java is, the Java programming language, the Java platform, JDK, the Java runtime environment, what a compiler is, what an IDE (integrated development environment) is, and how to write simple Java programs in IntelliJ IDEA, a modern Java IDE. I will demonstrate you how to write, compile and run Java programs with several code examples.
As a homework assignment, you will have a few hands-on exercises: writing a few simple Java programs, such as what I demonstrated to you, and submitting your solutions to the judge system.
Expressions and Statements in Java
In the next course section, I will talk about variables and data types (such as string, integer number, floating-point number, boolean and others), statements (which define the commands in the programs), the most used arithmetic operators (like plus, minus, multiply, divide and remainder) and the expressions in Java (or how to combine operators with values to implement a calculation).
I explain and demonstrate how to implement a console-based input and output in Java. I will show you how to read user input, format and print output to the console, and how to read and print text and numbers. I will teach you how to use the java.util.Scanner class to read text and numbers and how to work with integers and decimal numbers.
As a homework assignment you will have several hands-on exercises related to reading some data from the standard input, performing simple calculations with them and printing the results in a certain format.
In the next section I will explain and demonstrate how to write simple if-else statements in Java. Conditional statements (like the if-else statement, the switch-case statement and few other statements in Java) check some condition and if it is true, they execute certain block of code, otherwise they execute another block of code. We shall see how they work in practice and after that, as usually, you will have homework assignments.
You will have several hands-on exercises related to reading some data, performing a check and printing a result, depending on the input data and the checks.
Advanced Conditional Statements
In the next section of the free Java coding basics course, it’s time to start writing more complex program logic. I will show you how to use complex conditions in your if-statements: how to use the logical OR, logical AND, and logical NOT operators, as well as brackets, to design more complex checks. Additionally, I will demonstrate you through examples, how to write nested if-else statements, and longer sequences of if-else-else-if-else constructions. Together we shall solve several practical problems.
As usually, you will have a homework assignment: to solve a few hand-on exercises, that combine complex and nested conditions for processing some input data and calculating and printing certain results.
For Loops in Java
In the next course section I will teach you how to use the for-loop statement in Java, in its basic form.
In programming loops are used to repeat a block of code many times, typically for each value in given range. For example, we can write a for loop, which increases the value of a variable x from 1 to 50 and prints the value of x at each step. You will see how to do this in action, and then practice with the hand-on exercises, which I have prepared for homework.
In the next section I will explain the concept of while loops. While loops in Java allow code blocks to be repeated, as long as certain condition is true. Let’s see how this works in more detail.
As usually, I will explain the concepts to you through examples, then you’ll have homework exercises to practice your new skills from this topic.
In the next course section I will talk about nested loops. In programming, loops can be nested. This means putting another loop in the body of a loop. We can have several nested loops: we can have a loop in another loop, which holds a third loop.
And nesting is natural in the real world. For example, a building can have many floors and each floor can have many rooms. In this way we nest the floors inside the building and the rooms on each floor. If we want to walk around the building and print each of its rooms on each of the floors, we must use nested loops.
You will see how the nested loops work in action and then solve some practical exercises that I will give you as a homework.
Coding Exercises: The Most Important Part of This Course!
The most essential part of this practical Java training are the hands-on exercises: the homework assignments after each course section. The entire course provides more than 70 exercises, with automated grading in the SoftUni judge system. You should spend about 30 hours of coding to solve them. Yes, this is a serious effort, but it will pay off.
Remember that the only way you get practical skills is by practice: by writing code, by solving exercises. Watching video lessons can be pleasant and motivational, but you will never become a software developer by only watching videos. It is a good start, but it’s not enough.
Please, follow the exercises: solve the practical problems and send your solutions to the judge system for grading. You have more than 70 exercises to solve. Most of them were already solved in the video lessons, but the others were intentionally left for you.
