How would you rate your skills and knowledge in this field?

Self-assessment of skills and knowledge in Java depends on several factors:

• Knowledge of syntax and basic language constructs.
• Understanding of object-oriented programming.
• Experience with main libraries and frameworks (e.g., Collections, Streams, JDBC).
• Ability to write clean, maintainable code.
• Understanding of JVM operation principles, garbage collection.
• Experience in debugging and testing applications.

For an intern or a beginner, it is enough to confidently write basic programs, understand fundamental concepts, and be able to use standard libraries. As experience grows, knowledge of multithreading, design patterns, optimization, and application architecture is added.

It is important to be honest and specific, providing examples of projects or tasks you have worked on.
