Java · Basic to Pro

Java Programming — Full Course

This course takes you from your first public static void main to writing the kind of Java found in real enterprise and Android codebases — generics, the Streams API, and the basics of multithreading.

Every lesson is written, not filmed: read at your own pace, compile and run the examples yourself with the JDK, and use the Back and Forward buttons to move through the course in the order it was designed.

What you will learn

  • Core syntax: static typing, variables, and type casting
  • Operators, control flow, and the switch statement
  • Methods, parameters, and method overloading
  • Arrays and the ArrayList collection
  • Object-oriented programming: classes, encapsulation, and constructors
  • Inheritance, interfaces, and polymorphism
  • Exception handling with try/catch/finally
  • Generics and the wider Collections Framework (Map, Set, List)
  • Lambda expressions and the Streams API
  • Multithreading basics, including ExecutorService

Who this is for

No prior programming experience required. A strong foundation whether you are heading toward Android development, backend services, or enterprise software.
