The U.S. Bureau of Labor Statistics estimates that there are more than 1,469,000 software developers nationwide. According to 2021 data, 35.35% of those developers use Java , one of the five most widely used programming languages in the world.

Naturally, learning Java and becoming a Java developer is a smart career choice for anyone interested in software development.

In this comprehensive guide, you'll learn everything you need to know to become a Java developer. We'll break down the skills you'll need, the responsibilities of the job, and what you can expect your employer to pay you.

Let's get started!

What is Java?
Before you explore everything you need to know to become a Java developer, you'll need to understand what Java is.

Java is a programming language that developers use for mobile, software, and web development. A small team called “The Green Team” initially conceptualized Java in the early 1990s. That team included James Gosling, who later became known as the “Father of Java” for his work. Gosling developed Java while working as an engineer argentina phone number data at Sun Microsystems (today a subsidiary of Oracle).

Java was initially designed to be:

Simple
Robust
Portable
Platform independent
Sure
High performance
Multithreading
Neutral architecture
Interpreted
Dynamic
Since Java was released in 1995, many modern programming languages have descended from it, such as Python, Scala, JavaScript, and PHP . Naturally, Java has remained one of the most popular programming languages to learn .

Currently, there are four different editions of Java:

Java Card , which is used to develop programs for devices with low processing power (such as SIM cards and ATM cards)
Java Standard Edition (Java SE) , which people use to develop programs for desktop computers and servers.
Java Micro Edition (Java ME) , which is used to develop programs for mobile devices (such as iOS and Android phones).
Java Platform Enterprise Edition (Java EE) , which people use to develop large-scale applications.
