  • Classes & Objects: Understand how to create and use them.
  • Arrays & Collections: Start with arrays and explore collections like ArrayList and HashMap.

4. Practice Coding

  • Coding Exercises: Start with simple programs like reading input, calculating factorials, or creating a Fibonacci series.
  • Projects: Build small projects like a calculator or a to-do list app to apply theoretical knowledge.

5. Use Learning Resources

  • Online Courses: Platforms like Codecademy, JetBrains Academy, and Coursera offer structured courses.
