This 25-day OOP in Java course is designed to build a strong foundation in Java and object-oriented programming, starting with Java fundamentals such as program structure, data types, operators, input/output, control statements, arrays, and strings. It then covers core OOP concepts in depth, including classes and objects, methods, constructors, constructor overloading, and the use of this and super keywords. Learners will understand encapsulation through access modifiers and data hiding, inheritance using the extends keyword with method overriding and types of inheritance, and polymorphism through compile-time and runtime examples. The course also explains abstraction using abstract classes and interfaces, multiple inheritance through interfaces, and real-world design examples. Additional topics include exception handling, packages, wrapper classes, Java memory management basics, collections framework fundamentals, generics, file handling, and an introduction to multithreading. The course concludes with hands-on coding practice, real-time OOP scenarios, mini-projects, and interview-oriented questions to help students confidently apply object-oriented principles in Java applications.
