03 / FAQs
Questions before you start
How to learn Java? +
Start with basics (syntax, OOP), practice coding daily, build small projects, and take a structured course like this Java training, which covers core to advanced topics with hands-on labs.
Can I complete Java in 3 months?+
Yes! With 2-3 hours of daily practice, you can master Java basics in 3 months. For full stack Java (including frameworks like Spring), aim for 6 months.
This java programming for complete beginners course will accelerate learning with focused modules. So, don’t sweat, even if you’re new to this programming language.
What is a Java developer's salary?+
Salaries of Java Developers vary by experience, location, and full-stack skills.
- US: $127,887/year
- UK: £69,800/year
- Germany: €55,000/year
Is Java full stack in demand?+
Yes! Java full-stack devs (Java + Spring Boot + React/Angular) are highly sought after for enterprise apps, fintech, and cloud solutions.
Is Java used in AI?+
Indirectly. Java powers backend systems for AI/ML tools (e.g., data pipelines, APIs) but isn’t the primary language for ML modeling (Python dominates). Libraries like Deeplearning4j enable Java-based AI.
