Java Tutorial for BeginnersProgramming with Mosh
Mosh, a software engineer with two decades of experience, has taught over 3 million people how to
code and become professional software engineers. He has designed a Java course for beginners, which
aims to make Java simple and easy to learn, and he assures that he will guide every step of the way
throughout the course. IntelliJ IDEA, a free software program, is recommended for use throughout the
course. The main building block of Java programs are functions, and the smallest unit of these functions
is a block of code that performs a specific task. Mosh recommends that the main function is essential for
every Java program, as it is the entry point through which the program code is executed. Mosh also
promotes Code with Mosh, a coding school where students can find various coding courses to expand
their skillset. Additionally, he is sponsored by Dashlane, a password manager and VPN that is secure and
recommended by Apple and Google. A promo code, “MOSH,” is available for students who wish to
upgrade to the Premium plan and receive dark web monitoring or VPN services. While Mosh uses IntelliJ
for the course, he allows for students to use their preferred editor.A class in Java is a container for
related methods and is used to organize code. Similarly, packages are used to group related classes and
properly organize them as applications grow. The base package for a Java project is the reverse domain
name of a company. While a code editor may seem intimidating at first, it is easy to learn. The main
function, which is the entry point to a Java program, should be named using the pascal naming
convention. Additionally, classes are containers for related functions and methods are used to further
organize them. In Java, the public access modifier is used to specify the accessibility of a function. The
left brace is placed on the same line where a function is defined in Java. Building a command-line
application is often easier than building one with a graphical user interface. In creating a new Java
project, a new package and main class are established. Finally, the System class can be used to print
information on the terminal.
In this tutorial about Java, we will be discussing variables. Java uses variables to temporarily store data,
and there are two categories of types: primitive types and non-primitive types or reference types for
storing complex objects. While primitive types can store whole numbers without a decimal point,
integers can store values up to two billion. However, when dealing with larger numbers, underscores
can be used to separate every three digits for readability. It is important to note that if a number
exceeds the limit, an error message will be displayed. In the next tutorial, we will be discussing various
types in Java. Once the concepts have been mastered, a mortgage calculator project will be assigned to
test understanding.
IntelliJ is a Java-based programming environment that uses the Java compiler to compile code into Java
bytecode. Java is an incredibly popular programming language that was developed in 1995 by James
Gosling at Sun Microsystems, which was later acquired by Oracle in 2010. Currently, there are close to 9
million developers worldwide who use Java, and about 3 billion mobile phones run Java, as well as 120
million TV sets and every blu-ray player. Additionally, the average salary of a Java developer is just over
$100,000 per year in the US. This course is the first part of a complete four-part Java series, each part
being approximately three to four hours long. The first part will give you a solid foundation to start
programming in Java, and in the second part, you will learn about object-oriented programming. The
third part will cover core Java APIs. The course also teaches techniques used by professional
