How long does it take to become a Java developer?

With consistent practice (3-4 hours daily), you can become job-ready in 6-9 months. This includes core Java, Spring Boot, and databases. Reaching senior level typically takes 3-5 years of professional experience working on production systems.

Is Java still relevant in 2026?

Absolutely! Java remains one of the most in-demand programming languages. It powers enterprise applications, Android apps, and large-scale systems at companies like Google, Amazon, and Netflix. Java's stability, performance, and massive ecosystem keep it highly relevant.

Should I learn Java or Python first?

It depends on your goals. Java is better for enterprise development, Android apps, and building large-scale systems. Python is better for data science, scripting, and rapid prototyping. Java teaches you strong OOP principles that transfer to other languages.

Is Spring Boot necessary to learn?

Yes, Spring Boot is essential for Java developers. Over 60% of Java job postings require Spring experience. It's the de facto standard for building production-ready applications and microservices in the Java ecosystem.

Java vs Kotlin - which should I learn?

Start with Java. It has broader industry adoption and more learning resources. Once you're comfortable with Java, Kotlin is easy to pick up. For Android development, Kotlin is preferred. For backend enterprise work, Java is more common.

Do I need to learn microservices?

For senior roles, yes. Most modern enterprise applications use microservices architecture. Start with monolithic Spring Boot applications, then learn to break them into microservices. Understanding both approaches makes you more valuable.

What Java version should I learn?

Learn Java 17 or newer (LTS versions). Most companies use Java 11 or 17 in production. Focus on modern features like records, pattern matching, and virtual threads. Understanding older syntax helps when maintaining legacy code.

How do I get my first Java developer job?

Build 3-5 Spring Boot projects for your portfolio, contribute to open source, get certified (Oracle Java SE), and apply to entry-level positions. Prepare for technical interviews covering DSA, core Java, and Spring concepts.
