Java for Python Programmers: Book 1 is a structured introduction to Java for learners who already know some Python and want to build a solid foundation without starting from zero. Designed as a hybrid textbook-workbook, it combines clear explanations, side-by-side comparisons, Python Bridge notes, guided exercises, self-checks, reviews, and end-of-level projects.
Across five carefully sequenced levels, readers move from first contact with Java to core programming fundamentals, including program structure, output, variables, data types, input, operators, decisions, loops, methods, scope, and debugging. Each section starts with familiar Python thinking and then shows what changes in Java, why those changes matter, and how to write clearer, more deliberate code.
Suitable for school, university, bootcamp, and independent learners, this book provides a practical route into Java through small programs, workbook activities, and project-based practice.
