Introduction to Programming
Introduction to core programming ideas, Java's role, and the compile–run cycle.
What Is Programming
What is programming? Programming is the act of writing exact instructions that a computer can follow. Computers are fast and literal: they do exactly what we tell them, no more and no less.
- We use programming languages to express instructions.
- Instructions must be unambiguous and ordered.
- Small steps make complex tasks manageable.
Why Java
Why Java? Java is a general-purpose, object-oriented language used for servers, Android, tools, and more.
- Portable: write once, run on many platforms (via the JVM).
- Mature ecosystem: libraries, frameworks, and strong community.
- Performance: just-in-time compilation and modern JVMs.
